caring for buildingsCaring appropriately for buildings requires anunderstanding of how they are constructed andhence how they function – only then is it possible toidentify the right materials to repair them with.

We understand the technical qualities of each of ourproducts, this enables us to give the best possibleadvice and support for each project.

Careful product selection is vital to ensure the healthand longevity of your building.

caring for the environment All of our products are designed, assessed andselected to have minimal environmental impact. Wecontinually work to monitor and improve theenvironmental credentials of all of our products e.g.we have developed plasters that use recycled glassas an aggregate (instead of extracting virgin sand) orhemp fibres which are fully renewable.

We were the first company in Wales to gain ourBS8555 Environment Management System Awardunder the UKAS Accredited Seren Scheme. Itdemonstrates our commitment to the environment -from the paper we choose, to the way in which wedispose of any waste. It runs through every aspectof our business, we are not merely producing andselling these products because it is fashionable, it isabsolutely core to our business and always hasbeen e.g. our head office and training centre nolonger run on oil, they are heated through a heatrecovery system installed on the manufacturingyard, backed up by a biomass boiler - this meansthat we are saving up to 40 tonnes of carbondioxide emissions per annum! See page 47!

qualityWe have been determined to maintain the quality ofour products and services as the business hasgrown. In 2007, we gained our ISO9001:2000 quality

management system award helping to ensure thatwe continue to deliver the best possible productsand services through approved procedures.

caring for health Our products pose no health hazard to those usingor living with the materials. It is estimated that wespend up to 90% of our time indoors, so the qualityof the internal environment is important to our wellbeing. Our materials do not contribute to indoorpollution; in fact some of them actually help toimprove indoor air quality e.g. Ty-MawrTHERMAFLEECE® sheep's wool insulation actuallylocks in formaldehyde given off by heavily gluedproducts and our plasters, paints and boards help toregulate humidity, this is key to maintainingappropriate comfort levels in the room.

sustainability We want to contribute to a sustainable future – webelieve that one important aspect of this is throughsupporting local communities – we strive to buy andpromote local and British products. Where this is notpossible, we work to find the product with the bestecological and technical credentials and hope that ingenerating a market, a local product may eventuallybe produced. This has happened with several of ourproducts, most notably our sheep's wool insulationwhich is now made from Welsh wool, as well asreducing product road miles, this will contribute in asmall way to sustaining the rural communities inwhich we live and work.

innovation Finally, we are excited about combining new andtraditional materials in innovative ways. As a result,we have developed some award winning products:the insulated limecrete floor (pages 18-20) and theglaster® plaster and mortar (pages 22-24) and hemplime plaster (pages 13-15) ranges.

Benefits of Lime - caring for buildings

Lime has been used as the binder in mortars, plasters,paints and floors for centuries, it is usually blended withan aggregate to make mortar or an aggregate and fibreto make plaster/render.Lime has a proven track record, it has been used inarchitecture since 12,000 B.C. and there are plenty ofexamples from antiquity that still survive today (how manymodern buildings will be standing in the next hundred oreven thousand years, like the Parthenon built in 432BC).

We were cement-free in the UK up until the 1920s, sobuildings pre-dating this would primarily have beenconstructed of lime. It is staggering to think that all of thestone and brick buildings that we see around us every daylike Victorian terraces, Georgian streets, farmhouses,churches, chapels, barns, village halls, castles, cathedrals,stately homes and abbeys are all built without cement -and those that have been repaired and cared forappropriately with lime are still standing.

It is often thought that lime is not as 'strong' as cementand so has no place in buildings today, but lime has otherqualities, qualities that have helped traditional buildings tosurvive (very sustainable having buildings that last forcenturies!) and qualities that are now encouraging a newgeneration of builders/developers to incorporate lime intotheir new builds - creating healthier, more sustainablehomes.

> lime products are vapour permeable - this is importantin solid wall buildings as it means that any moisture isallowed to escape from the walls. This helps to controlcondensation and damp within the building (mostmodern renders, plasters, mortars and paints areimpervious, trapping moisture in the walls, leading toproblems such as condensation, mould growth and evendegradation of the fabric of the building such as timbersrotting, bricks/masonry crumbling).

> lime mortars are relatively flexible and willaccommodate some movement in a wall withoutcracking, each joint of lime mortar is like a miniexpansion joint. If lime cracks it can ‘self-heal’ whenexposed to air unlike its modern counterparts which areharder and hence more brittle. This allows movement andflex within structures whilst allowing them to remainupright! (just look up at the beautiful domed ceiling in agreat cathedral, only achievable because of this quality!)Often in earth quake zones, the 'traditional' buildingsconstructed of lime remain standing whilst modern'cement' buildings fall down as they are more brittle.

> lime mortars are sacrificial - so any salt or frost damageoccurs in the mortar not in the more expensivecomponents like brick/masonry.

Solid Wall Construction Building - maintained with soft,traditional, vapour permeable materials.

Solid Wall Construction - repaired with hard, modernimpervious materials potentially trapping moisture andleading to problems such as damp, condensation, mouldgrowth, wet/dry rot etc.

Caring for the environmentWe, as well as others, have been keen overthe last few years to highlight the potential oflime within new builds as a cementreplacement. The use of cement has grownenormously, by 2020, world production isexpected to top 3,500 million tonnes, threetimes the level used just a decade ago. 10%of worldwide Carbon Dioxide emissions areattributed to the production of cement (this iscomparable with the aviation industry). The cement industry itself has takenmeasures to reduce the impact but there arethings we can all do like consideringalternatives whenever we think about usingit in our buildings/structures. The range oflimes now available as well as the work wehave been doing in developing 'systems' hasmade the possibility of this much greater. See new timber-framed buildings (see page30), upgrading 'solid wall' constructions(see pages 32-33), warm roofs (see page 31)and limecrete floors (see pages 18-21).

> lime is burnt at a lower temperature thancement and so has an immediate energysaving of 20% (although kilns etc areimproving so figures do change). A standard lime mortar has about 60-70%of the embodied energy of a cementmortar. It is also considered to be moreenvironmentally friendly because of itsability, through carbonation, to re-absorbits own weight in Carbon Dioxide(compensating for that given off duringburning and so forms the well known limecycle - see opposite).

> lime mortars allow other buildingcomponents such as stone, wood andbricks to be reused and recycledbecause they can be easily cleaned ofmortar/limewash.

> lime enables other natural andsustainable products such as wood(including woodfibre, wood woolboards), hemp, straw etc to be usedbecause of its ability to control moisture(if cement was used, these buildings wouldcompost!).

Caring for health> lime is considered to be less harmful to

human health than many of its moderncounterparts:

■ lime plaster is hygroscopic (literallymeans ‘water seeking’) which drawsthe moisture from the internal to theexternal environment, this helps toregulate humidity creating a morecomfortable living environment as wellas helping to control condensationand mould growth which have beenshown to have links to allergies andasthmas.

■ lime plasters and limewash are non-toxic, therefore they do not contributeto indoor air pollution unlike somemodern paints.

Finally, lime products create a beautiful, lively,unique aesthetic that no modern material canreplicate....well we think so...

Impervious, hard cement render has beenremoved revealing rotten lintels and degradingmasonry caused by trapped moisture.

Lime allows bricks to be reclaimedready to be re-used, cement is sostrong that this is not often possible!.

Impervious modern paints prevent thewall from ‘breathing’ – it will blister, peeland flake and can lead to problems ofcondensation and mould growth.

Types of LimeThere are many types of lime on the market.It is crucially important to understand theirdifferences and the way in which theyperform, only then is it possible to make aninformed choice about which lime to use fordifferent applications and environments.

Slaked/High Calcium/Putty/Air/‘Fat’ or Non-Hydraulic Lime (see pages 7-15)This lime is produced by slaking freshQuicklime in an excess of water. It is alsoknown as non-hydraulic lime because itrequires exposure to air in order to carbonateand does not set under water. This lime isregarded as the most appropriate lime forold buildings where maximum permeabilityand flexibility is required.

Premixed ‘wet’ products are made from thislime putty with the addition of an aggregateand/or fibre.

Ty-Mawr’s premixed ‘wet’ lime products that are ready to use!

Hydrated or ‘Bag’ LimeThis is the lime generally available in buildersmerchants. It is a non-hydraulic limeproduced by slaking Quicklime with ashortfall of water which results in a powder.It is generally considered to be an inferiorproduct to the fat lime putty described abovefor a number of reasons but primarilybecause it starts to degrade from themoment it is made and can actually fullycarbonate in the bag before use. Widespreaduse of ‘bag’ lime has given ‘lime’ a poorname because of the instances where itsimply has none of its original properties leftby the time the end-user works with it, henceit fails, dusts etc. If ‘bag’ lime is the onlyoption, then it should be purchased as freshas possible and left to soak for two days inclean water. Although the resulting product ischemically the same as ‘fat’ lime putty, it isphysically different, in particular it is less‘sticky’.

Hydraulic Lime (see pages 16-17)In more recent years, hydraulic ‘hydrated’limes have been successfully produced fromlimestone containing clay and otherimpurities which gives it a faster initial set inmore extreme conditions (including underwater). There are many types of hydrauliclime and they are categorised according tothe following (NHL - Naturally HydraulicLime):

> Feebly hydraulic lime (NHL2) – containsless than 12% clay which means it isslower to set;

> Moderately hydraulic lime (NHL3.5) –contains 12%-18% clay which gives aslightly faster set;

> Eminently hydraulic lime (NHL5/Z) – has upto 25% clay content which means that amuch faster set is achieved.

These limes have become increasinglypopular over the last decade because of theircomparative ‘ease of use’ and ‘strength’,compared to fat limes.

For a dry, premixed hydraulic limemortar/plaster - see pages 22-25.

Pozzolans (see page 26)Pozzolans are ‘heated’ materials such asbrickdust, Pulverised Fuel Ash (PFA),Calcined Clay, that contain silica, aluminaand iron which become reactive towardsalkalis including lime. They are frequentlyused to help to give a fat lime mortar a‘faster’ set (essentially creating an ‘artificial’hydraulic lime) and are therefore helpful inmany situations to broaden the applicationsfor fat limes. It is believed that many historicmortars were ‘fat’ or ‘non-hydraulic’ as theyoften contain these ‘heated materials’ whichchange the performance of the mortar.Today, hydraulic limes are more commonlyused, sometimes wrongly, for increased setand strength. Please see below for someguidance on specifying and choosing theright lime.

PropertiesUnderstanding the properties of the variouslimes will help to ensure a successful resultthrough appropriate specification, see below.

The above diagram shows the ‘trade offs’ that need to beconsidered when choosing a lime - the stronger the lime, thefaster it sets but the compromise is ‘vapour permeability’ and‘flexibility’

Choosing a LimeIt is important for the well being of thebuilding that the most appropriate limeproduct is chosen. Every situation needs tobe carefully assessed e.g. in terms of:> softness of the stone, brick etc – this

should be a major factor in selection. Themortar should always be ‘softer’ than thestone/brick, see Lime Mortar table above.

> the environmental conditions – where theenvironment is very wet e.g. sea-defencewalls, canal walls, cellars, copings,pavings; a hydraulic lime is moreappropriate because of its ability to setunder water, see Lime Mortar table above.

Lime Mortar Selection

> the existing materials – repairing like-with-like – this will usually provide the mostsatisfactory solution both aesthetically and

technically, however it shouldnot be done without consideringthe performance of the originalmaterials, as well as the futuredemands.

> the time of year – the idealtime to do fat lime work,particularly external work, isduring the spring and earlysummer, lime work should neverbe done when the temperatureis likely to fall below 5°C before

carbonation has taken place (which can takemonths). Therefore, if work can not berescheduled to another time of the yearconsideration should be given to adding apozzolan to a fat lime (e.g. brickdust,calcined clay) to speed up the set or to using a hydraulic lime. Appropriate protectionis vital.

> the available time – occasionally work isprogrammed without enough time tosupport the use of the materials specified,rapid builds necessitate rapid sets thereforeadding a pozzolan to a fat lime or using ahydraulic lime should be considered (if work can’t be reprogrammed!).

Occasionally, the choice still seems to bebased on the availability of skills,unfortunately, lack of available skills meansthat often the stronger hydraulic limes oreven cement are introduced into buildingswhere they have no place and will, in the longterm, almost certainly contribute to dampproblems and damage the very fabric of thebuilding.

LimeProductsAggregates forMortars, Plasters& Screeds


To make a successful lime mortar or plaster,lime must be blended with an appropriatesand/aggregate.

It is important to choose a well-washed, well-graded sand which will aid workabilityand minimise shrinkage.

At Ty-Mawr, we have trialed and carefullyselected an excellent range of appropriateaggregates in a wide range of colours andtextures. This allows us to help you toproduce a mortar as close to the original aspossible where required (see mortar analysison page 11).

We carefully blend some aggregates toproduce a perfect grading for lime mortarsand plasters – see below – this saves timegauging different sands on-site as well asgiving the plaster/mortar the best possiblequalities in terms of aesthetics and ease ofuse to aid a successful job.

For those concerned about the level ofimpact caused by sand extraction, we offer acomprehensive range of recycled aggregates- better for the environment. Please callshould you want assistance with choosing anaggregate or see page 11.

Old and historic buildings will requirere-pointing as the mortar graduallydeteriorates over time.

By using lime mortar to re-point, it will ensurethat the building continues to function as itwas designed - see page 2.

A well re-pointed and well maintained wallwill not need re-doing for another centuryor so!

Our premixed lime mortars are ready-to-use, wet mortars that simply require‘knocking-up’ prior to use (in a drum or sitemixer or by using a whisk bit on a drill and abucket).

They are produced by blending our fat limeputty with specially selected British Standardaggregates in our automated productionfacility to ensure consistency and quality.

Benefits of pre-mixed mortar:> gives a consistent, accurate mix hence

removes the potential for mixing andgauging errors on-site.

> minimises waste - enables you to‘knock-up’ as much as you require in aday, anything left over can be reused, sonothing goes to waste.

Selecting a MortarIt is important when re-pointing an oldbuilding to select an appropriate mortar.

Consideration should be given to both thecolour and texture of the original mortar(unless it is to be subsequently limewashed).

The box of samples shows a selection of ourstandard mortars (see opposite) which mayassist your choice. Alternatively, you cansend us a sample of your mortar (the size ofa golf ball) for matching purposes.

Consideration must then also be given to thestrength and flexibility required for asuccessful, long term mortar – see page 5 orcall us for advice.

tipsWe do not addcement to any ofour products. To speed up theset or to increasethe strength, seepage 26 forpozzolans or callfor advice.

Note: a limemortar is not acement mortarwith a shovel ofhydrated lime in it!

Lime plasters were commonly used in mostbuildings as the internal finish from thehumble cottage to grand cathedrals, it is onlyin recent times that we have started to stripplasters off to reveal the stone or brick work.However, lime plasters have severalattributes, as well as helping to maintain thewell being of the building (moisture controland flexibility), lime plaster also has a ‘soft’aesthetic which gives older buildings aparticular ‘feel’.

Their ability to control moisture also makesthem a highly appropriate finish for use withother ecological materials such as straw,wood and earth, hence their increased use innew eco-builds.

Lime plasters also improve the quality of theinternal environment as they help to regulatehumidity by absorbing moisture thuscreating a healthier environment.

Ty-Mawr premixed lime plaster is a ready-to-use, wet plaster that simply requires‘knocking-up’ prior to use. For information onsuitable substrates - see page 6.

It is produced by blending our fat lime puttywith specially selected aggregates – coarsefor roughcast and base coats, and fine forthe top coats. This is done in our automatedproduction facility which ensures consistencyand quality.

Our premixed lime plaster can be suppliedhaired (synthetic or natural) or unhaired sothat hair/fibre (see page 26) can then beadded on site.

Benefits:> gives a consistent, accurate mix thus

removing the potential for mixing andgauging errors on-site.

> minimises waste - enables you to‘knock-up’ as much as you require in aday, anything left over can be reused, sonothing goes to waste.

> helps to keep the site organised andclean.

> high quality aggregate selectionproduces a very workable ‘fatty’ mix withminimal shrinkage.

Lime HempPlaster


Ty-Mawr’s Lime Hemp Plaster is a blend ofBritish lime (binder) and hemp plantfibres/shiv (aggregate), to make aplaster which is suitable for old buildingsas well as ecological new builds.

Why lime?> has been successfully used in building for

thousands of years.

> helps to control condensation and damp,thus creating a healthier building.

> enables other sustainable buildingmaterials to be used such as wood, straw,woodfibre boards, clay and earth.

> can be recycled at the end of its usefullife and will allow other buildingcomponents to potentially be reclaimedand re-used.

> is less damaging to the environmentcompared to its modern counterparts.

Why hemp fibre?> like all plants, the hemp plant absorbs

carbon dioxide as it grows (which is goodfor the environment).

> it is one of the faster growing biomasses,producing up to 25 tonnes of dry matterper hectare per year.

> it is a low input plant – it does not requirevast amounts of water or pesticides anduses no herbicides to grow, uniquely it alsoenriches and hence improves the soil inwhich it grows.

> it is now grown in the UK enabling us toproduce a fully British product.

> it is renewable and therefore does notdeplete a finite, natural resource (like sand)and so is more sustainable.

Where?> most conventional backgrounds – stone,

brick, block, our wood wool andwoodfibre boards, reed mat, reed boardand traditional battens/laths.

> internally as a plaster which can be left asa textured finish or trowelled smooth(n.b. for a completely smooth finish, thestandard top coat plaster (page 12) shouldbe used.) It can then be left unpainted orpainted with a vapour permeable paint.

> internally for dubbing out (filling hollows)in the wall prior to plastering (to allow aneven background for subsequent coats) orfor patching old lime plaster.

> externally for dubbing out and basecoats for a traditional lime or glaster® topcoat render.

Benefits> made from a natural, renewable plant

fibre (instead of depleting a naturalaggregate resource).

> has greater flexural strength thantraditional lime plasters making itextremely durable e.g. it is far moreresilient for use on corners, reveals andother vulnerable areas of the building.

> has some thermal properties and cantherefore be used to help improve theinsulation performance of the wall. It also adds to the thermal mass helpingto keep buildings warm in winter andcool in summer.

> can greatly improve the air tightness ofold buildings, improving the comfort ofthe room and offering energy savings,(10-15% of heat loss in old buildings isthrough air leakage and draughts).

> can be applied in much thicker coats(up to 25mm) than traditional lime plastertherefore is especially useful for ‘dubbingout’ hollows in walls prior to furtherplaster coats.

> is a successful way of ‘patching’ oldlime plasters e.g. where electricians/plumbers have been ‘chasing out’.

> is easier to use than conventional limeplaster (minimal shrinkage even on highsuction backgrounds) offering laboursavings.

> is vapour permeable and thereforehelps to regulate humidity safeguardingthe functioning and health of thebuilding. This makes it ideal for use inolder buildings.

> is beautiful - the coarse/medium plastergives a soft textured finish otherwise thefine hemp, glaster® or lime top coatplaster can be used for a smootherfinish.

tipsLime Hemp Plaster

is ideal forpatching old

plaster work andfor dubbing out.

StrengthTests show that the addition of hemp fibresto lime plaster dramatically improves thestrength of the plaster, this gives it severaladvantages:

> it is more robust and hence it is highlysuitable for use in vulnerable areas (e.g. corners, reveals) within a building.

> it has less ‘shrinkage’ which means lesstending and that it is ideally suited topatching/repairing existing plaster.

> it also means that no meshing is required(when applied in 10mm plus coats) and noadditional hair is required.

MoistureThe hemp fibres in the plaster actually retaina certain amount of moisture which is idealfor assisting carbonation (curing of lime)given the correct environmental conditions,this also means that it is especially useful for use on ‘high suction’ backgrounds suchas blocks where traditional lime plastersmight fail.

It is a ‘thirsty’ product and so is ideal intimber-frame panels as it helps to wickmoisture away from the timber, it is thereforeused as the 2011 version of daub in wattleand daub infill panels.

It is vapour permeable and so helps toregulate humidity, making a healthierenvironment - see below.

InsulatingThe addition of hemp fibre also improves thethermal properties of the plaster hence it isoften used as an ‘insulating’ plaster. It will notachieve the same performance as some ofthe other solid wall insulation solutions - seepage 33, but it does offer some advantagesincluding:

> less disruption internally

> easier to achieve air tightness

> no risk of cold bridging

> maintains the thermal mass of the wall whichhelps to even out the temperature internally

> simplicity and hence far less labour.

AvailabilityIt is supplied ready to use and can be mixedin an ordinary cement mixer. The premixedproducts offer consistency of mix as well asa cleaner site and minimal waste.

FinishingThe coarse/medium plaster gives a texturedfinish otherwise the fine hemp, glaster®

(can be coloured) or traditional lime top coatplaster can be used to give a smoother finish.

It can be left unpainted or painted with avapour permeable paint (see pages 48-72).

DaubClay and/or dung based daubs are primarily used now to repair the in-fill panels of timberframed buildings - wattle and daub. The daub is applied by hand to wattles which areinterwoven branches, laths (see page 26), or rods. Daub has a plaster-like consistency and caninclude straw and animal dung. After the daub sets, it is then limewashed (see page 28) tomake it more weather resistant.

Hydraulic Lime is produced from limestonecontaining clay and other impurities whichenables it to set without exposure to air(unlike fat lime products). It therefore meansthat these limes can be used in harsherconditions e.g. they are ideal for use infoundations, limecrete floors (see pages18-21), sea-defence walls, chimneys,parapets, copings, paving etc.

Hydraulic Limes are supplied as a powder towhich water and sand must be added in thecorrect ratios – see pages 8-9 for ourrecommended aggregates for use with lime.

HistoryWe know that lime has been used sinceRoman Times either as mass foundationconcretes or as lightweight concretes using avariety of aggregates combined with a widerange of pozzolans (fired materials) that helpto achieve increased strength and speed ofset. This meant that lime could be used in amuch wider variety of applications thanpreviously such as floors, vaults or domes.

Over the last decade, there has been arenewed interest in using lime for theseapplications again (after the domination ofPortland Cement over the last 50 years orso). At Ty-Mawr, we have been involved inresearching and developing different systemsfor lightweight insulated floors. The Ty-Mawrinsulated limecrete floor comprises of threelayers:

The insulating layerThis layer acts as a moisture break as wellas providing the insulation for the floor. We offer two alternative materials for thislayer recycled foamed glass aggregate orcoated LECA (Lightweight Expanded ClayAggregate). The recycled foamed glass offerssome environmental advantages in that it isrecycled (as opposed to depleting a natural,finite resource) and is fired at a lowertemperature to LECA. It also has asignificantly lower bulk density which offersenergy and cost savings in terms oftransport. It is also dimensionally stable(being angular) which makes it easier forthose working with the materials (pouring theslab). Unlike the LECA, it does require a light‘tamping’. LECA is the more economicalternative.

The limecrete slabThe limecrete slab is a blend of hydraulic limeand a natural lightweight aggregate - anaturally fired aggregate, that was extensivelyused by the Romans. The slab islightweight, vapour permeable and helpswith thermal resistance. It is this slab layerwhich is the main load-bearing element inthe floor, it is here that underfloor heatingpipes, if required, are fixed.

The glaster® screedThis layer is required if bedding thin tiles or ifunderfloor heating is to be incorporated intothe floor, it acts as the thermal store for theheat which is distributed through the pipes.

Again, in trying to improve the ‘green’credentials of the floor, our glaster® screed isa blend of recycled glass aggregate (asopposed to screeding sand) and a hydrauliclime binder.

Floor finishThe finish should be vapour permeable e.g.stone slabs or unsealed quarry tiles are idealbut please note they should be laid andpointed up with a lime mortar (we do apremixed bedding mortar - see page 24),timber flooring is also possible but should belaid loose on the floor for several weeks withthe heating running on low before permanentfixing. An air gap must be maintainedbetween the lime screed and the floorboards. This air gap is necessary to preventtimber from warping. However, it can affectthe performance of underfloor heatingsystems and so needs careful consideration.

Recycled foamed glass

Why do I need a ‘vapour permeable’floor?

The replacement of original ‘vapourpermeable’ floors such as earth, stone slabsand even timber in old buildings with modernimpervious damp proof membranes anddense concrete slabs potentially causesrising damp problems by creating a build upof water pressure beneath the membrane/slab, the moisture will move sideways until itreaches the existing masonry where it will beable to rise within the wall structure.

This situation is often exacerbated then byuse of waterproof cementitious renders andtanking on the walls which traps themoisture within the masonry. Replacing‘modern’ hard floors with this lightweight,vapour permeable floor can very quicklybegin to remedy this type of ‘old house’problem.

“The floor's performance has been verypromising. Though we have lowered it by afoot, there is no evidence of the seriousdamp problems that were evidentthroughout the year around the edges ofthe previous concrete floor.” PR, 2009

These qualities mean that our limecreteflooring system has been chosen by andsuccessfully installed in significant historicbuilding projects such as the Chapter HouseFloor in Worcester Cathedral, The PrioryChurch of St Mary and St Blaise, Chichester(12th Century), The Viscount Cowdray Estate,Surrey and by the National Museum andGalleries of Wales for the 13th CenturyChurch at St Fagans, but it is just as useful inbarns, farmhouses, terraces and cottages.

“…we had to find a method of controllingthe relative humidity levels within thebuilding so that both the historic, and newoak, timberwork would not be adverselyaffected. The use of a controllable under-floor heating system combined with aninsulated limecrete floor… was seen as anideal way of minimising such problems,enabling the building to dry out gently andnaturally, whilst moderating the internalenvironment for staff and visitors.”

EXTRACT FROM HERITAGE MAGAZINE BY DR GERALLT NASH,

CURATOR, NATIONAL MUSEUM OF WALES, ST FAGANS.

Why should it be insulated?In a response to global warming,governments the world over are settingtargets to ensure that buildings becomemuch more energy efficient.

Part L of the current Building Regulationsrequires a U-Value (thermal transmittance) of 0.22 W/m2K for a new thermal element(ground bearing floor) and 0.25 W/m2K for areplacement thermal element. Unlike roofs,walls and intermediate floors, U–Valuecalculations for ground floors cannot becalculated in the normal manner withreference to the construction detail alone.Heat loss from ground floors depends uponthe ratio of exposed floor perimeter to totalfloor area. It is therefore important toconsider all elements if your floor is going togive you the best possible performance foryour building. At Ty-Mawr, we design thefloor build-up for your specific floor tohelp you with the Building Regulations*,all you need to do is complete a simpleform available on www.lime.org.uk

“Thanks for your help in organising thematerials. I'm very satisfied with the resultsof the floors they were much easier than Ithought to lay - and much cheaper than allthe quotes I got from other people.”

DEL, MILTON KEYNES.

* In certain circumstances Part L Regulations do not apply tolisted building works, please discuss this with theConservation Officer in your Local Planning Authority.

Is it approved for use in buildings?Ty-Mawr’s insulated limecrete flooringsystem has an LABC system-type approvalto show that it can be capable of complyingwith current Building Regulations “subject tostandard calculations being undertakenand supplied by Ty-Mawr for eachscheme”.

Factors that influence the design include:

> wall thickness and construction type> floor area and perimeter length> substrate type> groundwater pressure> radon protection (permeable membranes

do not offer radon protection)> intended use> budget

StrengthIn general terms, the maximum strength thatit is possible to achieve using a lime basedmix is around 16-18 newtons/mm2. Thisexceeds the strengths needed in domesticconstruction by a considerable margin ofsafety.

Using the British hydraulic lime, the tests wehave commissioned show the followingresults:

Please note, it will continue to gain strengthover time.

Are contraction/expansion jointsnecessary?Our research has shown that theconsiderations applicable to cementitiousconcretes with regard to expansion joints arenot applicable to lime based concretes.Hydraulic Lime generates little heat duringthe initial chemical hydraulic set andlimecrete has a good flexural strength tocompressive strength ratio. Theseproperties mean that huge savings can bemade in terms of the labour and equipmentusually required to fabricate dowelled andinduced contraction joints in cement concreteground bearing slabs.

Can it be used with underfloor heating?If under floor heating is to be included in thefloor system, then a further layer of materialis specified – this is the glaster® screed layerwhich provides a thermal store for the heatdistributed through the pipe work.

Heat loss though the floor is controlled bythe insulation layer beneath (as detailedabove). No other insulation material isrequired beneath the screed but it is advisedthat you use suitable edge insulation wherethe screed meets any external un-insulatedmasonry.

InstallationIt is not unlike laying a conventional cement-based concrete floor; a contractor withexperience in laying floors should be willingand able to install it. Excavation, layerdepths and full installation instructions aresupplied with the flooring components. Ty-Mawr is renowned for its productsupport, providing telephone support andsite visits.

Plasters andMortars

glaster® plasterglaster® plaster is suitable for internal plastering as well as external rendering. It is available in a ‘coloured’ range – see below – which can be trowelled smooth or etched toreveal more of the glass aggregate. Alternatively, it can be painted with a vapour permeablepaint – see pages 48-61 for appropriate paints. We are also able to ‘tailor-mix’ a specific colour for you – please contact us to discuss yourrequirements.

Coloured range

Whilst every effort is made to ensure the accuracy of colour, due to the limitations in the print process, variations will occur.Please ask for an actual sample before specifying a colour.

glaster® external roughcast Using a coarser grade of crushed glass and by spray applying the product – a unique renderfinish can quickly be applied to blockwork, masonry, brick and building boards. The increasedsurface area of such a finish helps the evaporation of moisture, it is therefore an extremelyeffective finish for very exposed elevations.

LimeProductsLimewash


Ty-Mawr LimewashA traditional mineral paint made from fat limeputty. It “sets” when exposed to carbondioxide in the air. It is the ideal paint to useon lime plaster, masonry, brick etc as it ishighly vapour permeable. It has a matt finishand a 'depth' which most modern paintslack. It reflects light and appears to 'glow' insunlight.

Ty-Mawr Limewash is available as a creamyoff-white or a bright white to which pigmentscan be added. It is also available in a rangeof colours - see below, or we can tailor-mix aspecific colour for you - see page 29.

A coloured limewash tends to have a slightcolour variation across the surface; this slightblotchy effect is quite normal and is generallyconsidered to be part of its beauty.

The adhesion of limewash relies on suctionfrom the surface to which it is applied.It sticks well to lime plasters and renders,stone, brick and similar materials, but doesnot adhere so well to modern materials andfinishes - see pages 60-61 for alternatives.

Depending on the condition of the surface, it may be wise to apply a shelter coat. A shelter coat will provide an excellent ‘key’for the subsequent coats of limewash asoften, when limewashing over bare stone,especially if the stone is hard and non-porous, it can be difficult to get purelimewash to stick and/or remain on thesurface.

In some circumstances, it may be necessaryto help limewash bind (eg very exposedconditions). Casein, tallow or raw linseed oilcan be added for this purpose, but rememberthat any additive may compromise the'vapour permeability' of limewash to someextent. Please note we do recommend theaddition of PVA.

These colours have been achieved using 25ml of pigment per litre of natural emulsion(see pages 51- 52). The quantity of pigment required varies depending on the intensity of thecolour required. Limewash requires more pigment than any other paint. As a very roughguide, 500ml - 1 litre of pigment is usual in a 20 litre bucket of limewash.

Buildings and the Environment

Buildings have a profound effect on ourenvironment; more and more of ourclients are recognising this and hence therationale for using environmentally-friendlybuilding and decorating materials. The following help to illustrate this:> buildings are responsible for a large

proportion of Carbon Dioxide emissions inthis country - 50% results from energyused in buildings, 10% from theirconstruction.

> The Environment Agency’s trend datashows that around 2.5 million tonnes ofC&D (Construction and Demolition) wastewere handled in 2007 by waste facilities inWales. Nearly half of this waste waslandfilled, and only eight years of landfillspace remains in Wales.

> the development, use and maintenance ofbuildings result in the consumption of 6tonnes of building materials per person peryear in the UK. If we all choose low impactmaterials, we could really make anenormous difference!

Also applicable to solid brickwall and timber-framedbuildings – values will vary,please call for calculations.

glaster® or standard lime rendercan be used for top coats.Alternatively, the board systemcould be timber clad whichwould require counter battensand the boards would requiremechanical fixings.

Solid Wall Insulation - In the UK, 1 in 4 ofour homes has ‘solid’ walls, around 45%of the heat lost in an un-insulated solidwalled home is through the walls. In the drive towards energy efficiencyand carbon savings, we are all beingencouraged to insulate our homes butsolid walled buildings are designed toallow moisture to evaporate and thereforeany insulation solution must work in thesame way as the building to avoid theproblems that we now know areassociated with trapped moisture. If all solid walls were insulated there wouldbe a massive carbon dioxide saving of16,000,000 tonnes per annum(equivalent to the emissions from 2.7 million homes for a year).

How do I insulate solid walls?There are two methods of insulating solidwalls: externally and internally.

> External Wall Insulation - is installed fromthe outside effectively wrapping thebuilding. This type of installation methodwill change the physical appearance ofthe building (which will usually requireplanning permission) and will necessitatethe removal of rainwater goods and mayrequire adaptation of the roof and walljunctions as well as window and dooropenings as the wall is effectively beingmade thicker.

tipsAt Ty-Mawr, we areable to undertakeboth static anddynamic modelling ofproposed build-upsof systems to assessthe potentialcondensation riskand impact onperformance for yourbuilding.

EWI - Gutex woodfibre board

> Internal Wall Insulation - is applied fromthe inside and necessitates the removal ofall fittings e.g. radiators, skirting boards,architraves etc.

The options shown (below) are graphicalrepresentations of some of our solutions butplease contact us should you require anactual calculation and condensation riskanalysis undertaken for your specificsituation. Please note your architect shouldthen consider any problems of the site and

any detailing required such as use of abreather membrane.

The boards can carry various plastersincluding our lime plasters, glaster® andlime hemp products, the application guidesmust be followed for successful results – see www.lime.org.uk or call us for details.The components in these options aredescribed in more detail on the followingpages.

This is a highly vapour permeable plaster made from lime putty and hemp fibre instead of sand,it is therefore more sustainable than other plasters. It is the most economic and easy to apply (onetrade) IWI solution. It will save you energy and importantly, help to achieve air tightness in yourbuilding which will improve comfort levels (10-15% of heat loss in old buildings is through draughtsand air leaks). This option also adds to the thermal mass* and allows you to continue to benefitfrom it which will keep your building cool in summer and warm in winter. It is the least disruptiveas you will not necessarily need to move skirting boards etc. It is the least effective thermally andwill not achieve building regulations but it has significant advantages which makes it a popularsolution for our clients. It has a very appropriate aesthetic suitable for old buildings.

This board is applied directly to the lime plaster (no studding out required etc) using a proprietarymortar, but the surface must be even. It is hygroscopic thus helping to regulate humidity withinthe room and inhibits mould growth. It is the ‘thinnest’ of our solutions meaning that the leastamount of space is lost internally. Just 30mm can reduce your energy consumption by 40-50%.Reveal boards are available to cope with window openings and sections can be made to orderto accommodate plaster covings etc. It is easy to cut and work with. It is the most expensive interms of material cost of our options but there are labour savings on-site.

We have various woodfibre boards for this application – see pages 38-41 which can easily meetor exceed current building regulations requirements. It requires an even background of lime plasterand can be adhered using a lime plaster. It is vapour permeable and so allows the safe passageof moisture which is essential for solid wall insulation. It isolates the thermal mass from the roombut it means that the room will heat up quicker. Various thicknesses are available which will givedifferent overall thermal values for the walls, as well as reveal boards to cope with window anddoor openings. Joints and fixings must be well executed to avoid thermal bridging.

This system is the most economic in terms of materials of all of the options that can meet buildingregulations (presented here). It is more involved in its detailing and installation, studding out isrequired and great care must be taken to avoid any thermal bridging. It will make a huge contributionto comfort levels and energy costs. It again isolates the thermal mass but will allow the room towarm up quicker. It is vapour permeable, a breather membrane should be used on the cold sideof the insulation if there are high moisture levels in the wall. Call for advice!

This newly launched semi rigid boarded product can be easily cut and fixed to level plasteredwalls. It can be finished with a wood wool board and lime plaster. Although the material costs arehigher than the other options, it offers a solution that complies with building regulations, is Britishand has the best thermal performance of any of the ecological boards. It has no glues and isconsidered to be one of the most sustainable solutions. It gives an 86% improvement but againisolates any benefit from the thermal mass. Careful attention to detailing and fixing is again requiredto avoid thermal bridging.

These figures are for illustrative purposes only – different walls perform differently and variousstudies show that this data in most software is not always accurate when it comes to stone walls!Please contact us to discuss your specific project.

*Thick, solid wall buildings have high thermal capacities which means that they absorb heat slowly over time and release it relatively slowly as the surroundings cooldown. This can have a significant stabilising effect on the internal environment, keeping the building cool in summer and warm in winter.

Benefits> helps to keep buildings cool in summer

and warm in winter. Cool in summer -when the outside temperature increasesand begins to heat the wool, it releasesmoisture; that has a cooling effect on thefibre which reduces the flow of heat tothe inside of the building. This canreduce peak temperature by up to 7°c.Warm in winter - the absorption ofmoisture by wool insulation can increasepeak temperature by up to 4°c whencompared to buildings in whichalternative forms of insulation areinstalled.

> can absorb and desorb water vapourwithout compromising its thermalefficiency. It is therefore ideal for use inroofs, timber frame and solid walls as itavoids a damaging build-up of moistureby allowing water vapour to migratethrough the structure see pages 30-33.

> uses only 14% of the embodied energythat is used to manufacture glass fibreinsulation, therefore paying back itsmanufacturing energy cost seven timesfaster than glass fibre.

> is harmless and can be installed withoutgloves or protective clothing.

> has a life expectancy similar to that ofthe construction in which it is installed;other cheaper modern installations havea lesser life expectancy, making thewhole life cost of wool much closer tothose materials.

> exclusive to Ty-Mawr, of the woolcontent, we can guarantee that there is aminimum content of 75% Welsh wool.

> can be recycled for otherenvironmentally friendly applications atthe end of its useful life. It contains nopermethrin, pyrethroids, pesticides orformaldehydes.

> it has a higher fire resistance thancellulose and cellular plastic insulants;it does not burn but rather melts awayfrom an ignition source and extinguishesitself. Ty-Mawr THERMAFLEECE® istreated with a natural fire-proofing agentto improve its intrinsic fire resistance andcomplies with BS 5803-4 (Spread of Fire)achieving results of zero for ignitability,spread of flame and heat evolved.

Calsithermclimate board

KP-mortar

Existing Lime plaster

Calsitherm Climate BoardThis board is newly available in the UK. It is is made from calcium silicate, a micro porousmineral building material with effective insulating properties, its high capillary action ensureshumidity regulation and the nature of the material means that mould cannot form on itssurface.

Unlike most other insulation boards on the market, the Calsitherm Climate Board can bedirectly applied to the existing internal plaster without the need to carry out stud work tocarry the board.

The diffusion-open, capillary active calcium silicate interior insulation compensates forhumidity peaks in the room air and helps regulate the climate in the room. The capillary activityensures the moisture in the insulation is drawn away and quickly distributed into the room overa large area. It therefore compliments traditional, solid wall construction buildings that need tocontinue to deal with moisture!

Benefits:> reduced energy consumption and hence

heating bills.

> easy to work with and install.

> increased value of the restored building.

> improvement of room climate.

> carries a traditional lime plaster.

> maintains the moisture control within thebuilding whilst insulating.

> no need to apply timber-studding to thewall - can be directly applied to existinglime plaster!

The Brecon Beacon’s – Ty-Mawr’s Back Doorstep! Snow & climate change - Somewhat counter-intuitively, a warmer world couldlead to more snow in some places. In warmer areas there is likely to be more evaporation, which means more moisture in the airand makes for more extreme precipitation. If this moisture travels to colder areas, this will still fall as snow. A warmer world doesnot mean that there will be no cold places!

AGLAIA has been producing plant-based wallpaints since 1968. We recommend them for anumber of reasons.

Benefits> they are made from environmentally-

friendly, renewable materials;conventional paints are still often basedon petro-chemicals (causing hugeenvironmental problems) and fossil fuelslike crude oil (that are too precious toburn).

> there is no human health hazard tousers or those living and working in thespace afterwards.

> 100% VOC-free (volatile organicchemicals!) naturally.

> their products have a full declaration ofingredients and descriptions of theircomposition and origination, unlikemany of the paints claiming to be 'green'on the market today.

> they are technically good i.e. easy-to-use, hard-wearing and proven over alarge number of years on thousands ofsquare metres of wall and wood.However, because they do not haveconventional artificial drying agents etc,instructions must be followed.

> they are highly vapour permeable andtherefore compatible with other naturaland traditional building materials.They can directly help to control damp/condensation within a building.

It is our objective to provide,through our technical information,advice based on our skills andpractical experience. Anyinstructions given are non-bindingand do not release the user fromhis or her liability to check forproduct suitability and applicationmethods him/herself with regardto the surface used. Technicalmodifications may result fromproduct development. Uponpublication of a revised or newversion, these instructions willautomatically lose their validity.

Historically, paints have been used as both a protective skin and as a decorative surface onwalls as well as woodwork and metal.

Over the last decade, we at Ty-Mawr have carefully designed and selected a unique paint rangewhilst considering the needs of our clients, those of their buildings as well as the environment.

As more and more paints come on to the market, it is important to understand what youtechnically require from your paint as well as considering how it is made. The table on pages 60-61 gives an overview of the main options.

Paints &FinishingProductsBeeck’s Internal

Wall Paints


Beeck's mineral paints have beenmanufactured in Germany from waterglassfor well over 100 years. Their popularitythroughout Europe is based on theirincredible durability as they actually bond tothe surface to which they are applied -becoming part of the fabric of the building.Just as importantly, they function in the sameway as the building i.e. they continue to letolder buildings ‘breathe’. They have thereforebeen widely used amongst professionalsinvolved in old and historic buildingconservation. As they have no artificial resins,solvents, biocides etc, they are also thechoice of those concerned about the healthof the painters and building occupants aswell as those concerned about theenvironment.

The product range is extensive, with paintsthat can perform in a huge variety ofsituations and on different backgrounds(outlined here for internal paints and on page69 for the external range).

Benefits:> they have an excellent historic pedigree

dating back to 1884.

> Beeck’s mineral paints actually formactive silica bonds with the background(i.e. they become part of thebackground). This is what gives themsuch incredible durability.

> they have a “breathability” (water vapourpermeability) comparable to limewash(with an Sd value of <0.02m), whichresults in healthier and drier buildings.

> they are completely non-toxic andcontain no VOC’s, this makes them safefor you and your family to work and livewith.

Please note these paints rely on a naturalchemical reaction occurring to perform attheir best - this requires the right primer toenable the silification process to take place -see table on pages 60-61. Always refer to thetechnical sheets.

INSIL Primer – a white primer for gypsumplasters and plasterboards, use prior toapplying Insil Internal Paint. Coverage – 7 square metres per litre.

INSIL Internal Paints – a solvent-free, openpored interior silicate paint. Available in whiteor any of the colours shown in the Beeck’scolour on pages 54-55. This paint is not apure silicate – it has 4% artificial resin whichhelps it to bond to difficult surfaces e.g. where modern emulsion may have beenused. It is still highly vapour permeable andtherefore ideal for rooms with a variety ofbackgrounds e.g. new plaster with oldpainted walls. Coverage - 8 square metresper litre.

tipsAlways try samples first especially on old/unknown wood

and terracotta or stone tiles.

Wood, cork and open pored stone and ceramic tiles arevapour permeable as long as they are not sealed with

impermeable sealers and paints. The Aglaia range of oils andwaxes will maintain vapour permeability by lining but not

clogging the pores thus helping to control moisture. This is especially important with wood that will move and flex

with changes in humidity and temperature!


Aglaia WoodPrimers


Aglaia Weather Protection Lacquer – ahighly weather resistant plant oil paint forexternal and severely weathered wood, andexternal steel. Ideal on doors, windows andrainwater goods. No tendency to peel evenwhen subject to intensive weathering. Gives a durable, semi-gloss finish.

Aglaia Internal Lacquer - a pigmented plantoil paint for coating wood and metal indoors,furniture and items in daily use. Gives adurable, matt eggshell finish.

Both paints are available in white, a standardrange of colours (below) as well as a widerange of shades and tones (see pages 65-66), designed to complement our naturaland traditional wall paints.

Please note – dust free after 8 hours, safe tocoat after 24-36 hours. Must be dilutedaccording to manufacturer’s instructionsusing balsam lacquer thinners – see page 68.Coverage – 10 square metres per litre.

Standard RangeWhite (W), Ultramarine Blue (UBL), Oxide Red (OR), Green(G),Yellow Ochre (YO), Brown (B), Umber (UM), Black (BL)

The absence of acrylic in these paints means that they move and flex with the wood withchanges in moisture and temperature without peeling or flaking. They are also ‘vapour-permeable’ and so allow the wood to ‘breathe’. These properties mean that they are moredurable than most modern ‘more economic’ wood paints.

Beeck’s Mineral Paint

Beeck's mineral paints have beenmanufactured in Germany from waterglassfor well over 100 years. Their popularitythroughout Europe is based on theirincredible durability as they actually bond tothe surface to which they are applied -becoming part of the fabric of the building.

Just as importantly, they function in the sameway as the building i.e. they continue to letolder buildings 'breathe'. They have thereforebeen widely used amongst professionalsinvolved in old and historic buildingconservation. As they have no artificial resins,solvents, biocides etc, they are also thechoice of those concerned about the healthof the painters and building occupants aswell as those concerned about theenvironment.

These paints are highly technical, theirexcellent properties and great durability relyon correct primers and application. See table on page 70.

Benefits:> they have an excellent historic

pedigree dating back to 1884.

> Beeck are one of a small number ofmanufacturers who currently producethese single component mineral paintsthat still form active silica bonds with thebackground. This is what gives themsuch incredible durability - lasting manydecades.

> they have a “breathability” (watervapour permeability) comparable tolimewash which results in healthier anddrier buildings.

> they protect against natural andchemical weathering, smog, and dirtpenetration, algae and fungal growthand are incombustible and light fast.

> they are completely non-toxic andcontain no VOC’s, this makes themsafe for you and your family to work andlive with.

While every effort is made toensure the accuracy of colour,due to the limitations in the printprocess variations may occur.We recommend the purchase ofsample pots for testing in situ.

Painting Apply two coats of Beeckosil diluted with Fixative (20% first coat, 5% second coat) using a mineral brush or sprayer (ifexperienced). It is vitally important to apply it evenly keeping a wet edge going so that it is lap-free. Complete single elevations inone go. Allow at least 12 hours to dry. Avoid painting in wet or cold weather (below 5°c).

*For new concrete, mould oil remover should be applied followed by Beeckosil (dilute with 10% Fixative for first coat and 5% second coat).

Surfaces should be clean, dry, stable, salt and plant-free before applying the Beeckosil system. The paint does not hide differences in thebackground, therefore correct products should be chosen and all products must be carefully and evenly applied.

It is ESSENTIAL that full technical sheets and application guides are consulted and test panels undertaken to ensure suitability. This tableindicates the steps for most usual conditions, and is for basic guidance only. For mineral surfaces, the Earthborn Silicate Paint is also available.See page 72.
