Gypsum Industries manufactures an extensive range ofplasterboards which, as part of a building system aredesigned to meet specific requirements relating to soundinsulation and resistance to fire, moisture and impact.The tables below provide information on typicaldimensions and edge profiles available.

Reaction to FirePlasterboard linings provide good fire protection owingto the unique behaviour of the non-combustible gypsumcore when subjected to high temperatures.

Within national Building Regulations, plasterboard is designated a ‘material of limited combustibility’. As a result of the performance achieved when tested to BS 476: Part 6: 1989 and BS 476: Part 7: 1997, the surfacesof Gyproc plasterboards and the exposed plasterboardsurface of Gyproc thermal laminates are designated Class 0.

Board weightsAll weights stated in the following tables areapproximate. Board weights can vary. If the boardweight is critical to the design, please contact theTechnical Sales Department.

Glasroc F Multiboard and Glasroc F Firecase are paperless,glass reinforced gypsum boards, which are designated as ‘non-combustible’ when tested to BS 476: Part 4: 1970(1984).

Technical Guidance Document B (Fire Safety) of the BuildingRegulations was amended in 2006 to also allow the‘Euroclass’ system to be used for demonstrating compliancewith reaction to fire requirements. The following tables listthe ‘Euroclass’ reaction to fire classifications.

Key facts

Jointing materials

Gyproc jointing materials produce a smooth, continuous,

crack-resistant lining surface ready for priming and final

decoration. A number of jointing specifications are

available to suit the board type, site preference and

method of application - manually using hand tools or

mechanically using Gyproc Speed Tape tools. After joint

treatment has dried, the complete lining surface is treated

with Gyproc Drywall Primer to prepare it for application of

paint or wall coverings. Gyproc Drywall Sealer can be used

in two coats to provide water vapour control.

Stage 1 Stage2 Stage 3

(Gyproc Paper Joint Tape & Bulk Fill) (Secondary Fill) (Finishing Coat)

Air-dryingJointing compounds used for the finishing application, by theirvery nature, are applied more thinly than fillers and so musthave air-drying characteristics in order to harden sufficiently atfeathered edges. Air drying materials can be applied by handor machine using Gyproc Speed Tape tools. Air drying materialsmay be used as fillers but greater time needs to be allowed topermit the material to dry in depth, particularly in coldconditions. Air-drying materials should not be used for fixingcorner tapes or beads.

Air drying versus setting

SettingJointing compounds used for the joint filling stage(s) areusually setting products. Hardening is not dependent uponatmospheric humidity. Fillers that only harden by thesetting process are hand applied and have low shrinkage.When a setting product is applied as a thin layer it may ‘dry-out’ before it has properly hardened. Setting materials aretherefore unsuitable for the finishing application.

INSTALLATION OVERVIEW -


66

www.gyproc.ie

EnvironmentalGyproc jointing materials are unsuitable for use in areassubject to continuously damp or humid conditions.

Preparation1. Boards should be securely fixed, with no steps betweenadjacent boards.

2. The correct fixings must be used and properly located withtheir heads just below the liner surface. Any protrudingscrew heads should be driven home using a hand screwdriverprior to spotting and jointing.

3. Jointing materials should not be applied to frozen surfacesand should not be used at, or subjected to, temperaturesbelow 4ºC during setting or hardening.

Joint reinforcementIn a plasterboard system, suitable joint reinforcement isessential to minimise the risk of cracking along the joints,which then appears through the decoration. To achieve theobjective of a smooth continuous crack-free surface, taperededge plasterboard and Gyproc Paper Joint Tape are widelyregarded as best practice when jointing or plastering. Thetapered edges provide a recess for the joint treatment soallowing a flat, finished surface. At board joints, where cutedges or square edge boards occur, the joint treatment isinevitably raised above the board surface and is more difficultto conceal. In this situation the second and third stages arecarried out using a Gyproc finishing product and jointtreatment is feathered-out into the field of the board in orderto conceal the joint as much as possible.

Joint treatment has two essential components - thereinforcement and the jointing compound. Reinforcement isnecessary where there is relative movement of adjacentboards. In practice movement of the background structure ispossible and Gyproc Paper Joint Tape bedded into a jointingcompound is recommended for the best crack resistance.

Self-adhesive fibre tapes are an alternative, and can be easyand quick to install on flat joints. They are not, however, adirect substitute for Gyproc Paper Joint Tape, as tests haveshown that Gyproc Paper Joint Tape provides superiorresistance to cracking.

In fire-rated applications Gyproc Paper Joint Tape must beused.

FillingTapered Edge Joints1. A continuous thin band of Gyproc joint filling materialshould be applied to the trough of the tapered edge joints,making sure that no area is left uncovered. The requiredlength of Gyproc Paper Joint Tape should be pressed into theband of filler. The tape should be firmly bedded withsufficient joint filler under the tape to ensure good adhesion.The filler should be brought flush with the surface of theplasterboard.

2. Immediately after the filler has set, or dried out fully, asecond layer of filler should be applied over it. This shouldalso be brought flush with the surface of the board.

3. Once the second application of jointing material has set oris fully dried out, apply a finishing coat of ProMix Filler &Finish. The finish coat should be feathered out into the fieldof the plasterboard.

At all stages, any surplus material should be wiped from theedges of the joint with a moistened joint sponge, taking carenot to disturb the main joint material.

Square Edge Joints1. A continuous thin band of Gyproc joint filling materialshould be applied over the joint, making sure that no area isleft uncovered. The required length of Gyproc Paper JointTape should be pressed into the band of filler. The tapeshould be firmly bedded with sufficient joint filler under thetape to ensure good adhesion. Apply a 200mm widecontinuous band of Gyproc joint filling material along bothedges of the bedded Gyproc Paper Joint Tape.

2. When the first application of jointing material has set or isfully dried out, apply a second application of Gyproc jointfilling material. This coat should be applied at 250mm widealong both edges of the Gyproc Paper Joint Tape.

3. Once the second application of jointing material has set oris fully dried out, apply a finishing coat of ProMix Filler &Finish. The finish coat should be feathered out into the fieldof the plasterboard.

At all stages, any surplus material should be wiped from theedges of the joint with a moistened joint sponge, taking carenot to disturb the main joint material.

Nail / Screw Head SpottingThe indentation should be filled with a layer of Gyproc jointfilling material struck off level with the face of the board andallowed to set. After a second application of filler, the processis completed with an application of ProMix Filler& Finish.

Gyproc Drywall Primer and Drywall SealerSpecially formulated for use on the surface for directdecoration of plasterboard. Applied in one application, afterthe jointing has dried, by brush or roller, it prepares thesurface for paint and wallpaper decoration. Forpaperhanging it allows the paper to be wet-stripped whenredecorating. For painting it primes, providing a consistentbackground for the first coat. Where a vapour check isrequired two coats of Gyproc Drywall Sealer can be used as analternative to the Primer. A water vapour resistance of atleast 15MNs/g is achieved.

Supplied in 10 litre containers

Cut edges

A similar finish to that obtained with tapered-edge boardscan be obtained with cut-edge boards or a cut-edge andtapered-edge board. The cut edges should be lightly sandedto remove any paper burrs. The joint should be filled flushwith the face of the board using a Gyproc joint filler and allthe stages of jointing carried out as outlined above.

Angle Reinforcement

Internal anglesGaps between the boards should be filled with a Gyprocjoint filler. A thin layer of filler should be applied to bothsides of the angle. The joint tape should be folded andpressed into the angle, making sure that air bubbles areremoved. At this stage, the tape on both sides of the angleshould be covered by a layer of filler. Sufficient joint fillershould be left behind the tape to ensure good adhesion,and feathered out with the jointing sponge. Surplusmaterial should be removed with the sponge. When thiscoat has dried a Gyproc joint finishing material should beapplied to both sides of the angle and the edges featheredout with the jointing sponge.

When the internal angles are formed at the junction ofwallboard and plastered walls or ceilings, the abovetreatment should be carried out but it may be necessary toapply a narrow band of pva sealer to the plastered surfacesbefore applying joint filler.

External anglesWhen external angles are formed, any cut edges should bemasked by a bound edge. If two cut edges occur together,the exposed edges should be given a brush coat of pvasealer. External angles should be reinforced with eitherGyproc Corner Tape or Gyproc Angle Bead.

Gyproc Corner TapeThe tape should be cut to the length required and creasedfirmly at the angles to allow the steel strips to lie close tothe wallboard surfaces.

A 50mm wide band of Gyproc Joint Filler or Gyproc ProFillshould be applied to each side of the angle. The tapeshould be pressed firmly on the corner, making sure thatthe arris of the folded tape is straight. Immediately afterbedding the tape, a 100mm to 125mm band of Gyproc JointFiller or Gyproc ProFill should be applied to both sides ofthe angle with the applicator. The edges should befeathered out with a moist sponge. After this coat of fillerhas set, a layer of finish should be applied and the edgesagain feathered out with the jointing sponge.

Gyproc Angle BeadWhen maximum protection is required for the externalangle, Gyproc Drywall Metal Angle Bead should be used.25mm bands of Gyproc Joint Filler or Gyproc ProFill shouldbe applied to both sides of the angle formed by thewallboard. The angle bead should be positioned on thejoint filler with its wider flange covering the joint betweenthe wallboards. It should be pressed firmly into place withthe outer edges touching the wallboard surface. Materialwhich has been squeezed through the holes and at thesides should be struck off flush and the remainder allowedto set. At this stage, the angle bead will tend to move ifmore joint filler is applied. If necessary one or twomechanical fixings may be used to ensure that the bead isnot dislodged while the filler is setting. The nails should beremoved after the filler has set.

When the joint filler has set, another layer should beapplied and feathered out. The surplus material should beremoved with the sponge. After this layer of joint filler hasset, a coat of finish should be applied to each side of theangle, 50mm beyond the edge of the joint filler.

Health and SafetySafety Data Sheets for all Gypsum Industries’ are availableto download from our website: www.gypsum.ie, or via theTechnical Sales Department.

Detailing at junctionsDesigners must give consideration to the precautionsnecessary at junctions to ensure that moisture is not allowedto penetrate, collect, and cause problems or deterioration inwalls and floors, e.g. at the base of walls where showers arespecified with tiling to plasterboard, and at other junctionssuch as bath edges.

Perimeter sealingStandard perimeter sealing methods around baths or showertrays are normally adequate. Caulking sealant can be used toform a fillet between the wall surface and the floor at thebase of partition or wall lining to prevent any possiblemoisture being absorbed by the board core. Alternatively, theboard ends can be protected by lengths of suitable channel orself-adhesive plastic tape.

TolerancesThe tolerance on the finished tile surface will reflect veryaccurately the standard of the background surface. This isparticularly important on timber framed backgrounds.Therefore, the standard required of the finished tiled surfacemust also be applied to the timber framed wall.

BoardingAll partitions and wall linings should be complete. Thereshould be no omissions to board linings, e.g. behind baths.

Timber stud external walls or partitionsWhere ceramic tiling is specified, designers should ensurethat the timber is of sufficient dimensions to give a stablebase for the additional loading.

Movement jointsReference should be made to all relevant standards, includingceramic tiling standards.

FinishingBefore tiling commences, any tapered edge joints includedwithin the tiling area should be filled with tile adhesive. Other areas are finished as normal. Please refer to Section

- Finishing Coat Plasters, Section - Jointing andSection - Decorative effects.

CharacteristicsGyproc Placocem tile backer is a cement board that combines

a cement mixture with expanded polystyrene beads, inserted

between the two faces of the panel and is ideal for use as a

Tile Backer Board for wet and humid areas.

The unique composition of Gyproc Placocem Tile Backer

Board creates a board with excellent resistance to moisture in

internal applications. The board remains lightweight relative

to other cement based boards and easy to handle due to the

inclusion of expanded polystyrene beads within the core.

ApplicationsGyproc Placocem Tile Backer Board is a superior tile substrate

for walls, specifically designed to meet the demands of high

moisture areas.

Gyproc Placocem Tile Backer is suitable for tiled, untiled, wet,

dry and higher humidity applications

Board colourGrey - Face.

Grey - Reverse.

Board printingFace - printed (product name and board thickness)

Edge - blank

Reverse - blank

Board performanceMoisture resistanceGyproc Placocem Tile Backer Board offers excellent moisture

resistance properties, resulting in less than 180 g/m2 of

surface water absorption after two hours of full immersion.

Gyproc Placocem Tile Backer Board offers 8.7% water

absorption after 24 hours at atmospheric pressure, and

12.4% water absorption after 24 hours after vacuum

separation. It is therefore a product considered suitable for

use in areas subject to intermittent moisture, such as

wetrooms, bathrooms and kitchens.

Fire protectionGyproc Placocem Tile Backer Board achieves an A2- s1, d0

Reaction to fire classification.

Fire resistancePerformances achieved on systems using Gyproc Placocem

Tile Backer Board will depend on the board type and

thickness, the number of layers used, the stud type and the

choice of cavity insulation used. Please contact the Technical

Sales Department for guidance.

Sound insulationThe mass and sound absorbing qualities of Gyproc Placocem

Tile Backer Board enable high acoustic performance to be

achieved. Performances will depend on the board type and

thickness, number of layers, stud centres and type, fixing

centres and choice of cavity insulation requirements.

Attaching loadsLoads with a weight of less than 10 kg per point of

attachment can easily be fixed to the wall with suitable

screws. Loads with a weight of up to 30 kg can be attached

directly to the panels using expansion bolts or cavity fixings

providing that they are at least 400mm apart. Loads with

weights exceeding 30kg should be affixed to the sub layer

construction. It is advisable to contact the Technical Sales

Department for guidance. Loads exceeding 30kg require

additional detail (patressing). Contact the Gyproc technical

office for guidance.

Thermal conductivity0.20 W/mK

Surface hardnessWhen tested using the Brinell Hardness Test method, the

surface hardness of Gyproc Placocem Tile Backer Board is

greater than 42 N/mm2 whereas standard plasterboards have

a surface hardness of approximately 18 N/mm2.

Gyproc Placocem Tile Backer Board is equivalent to

Type I plasterboard in accordance with the EN 520 surface

hardness test.

Duty ratingThe use of Gyproc Placocem Tile Backer Board in Gyproc

systems can achieve a ‘severe duty rating’ according to BS

5234: 1992: Part 2. For further information contact our

Technical Sales Department.

TemperatureGyproc Placocem Tile Backer Board is not suitable for use in

temperatures above 90ºC.

Effect of condensationGyproc Placocem Tile Backer Board is vapour permeable,

however, should the vapour condense on the surface of the

board, the board will retain it’s strength.

Board storageThe boards must be stored on a flat base, sheltered from

frost, sun and moisture.

The boards are supplied covered. it is advisable to keep them

covered on site for as long as possible, even when the stack is

in use.

Gyproc Placocem Tile Backer Board comes in stacks of 30 with

a packer pallet dividing the stack into two blocks of 15.

Gyproc Placocem Tile Backer Board should not be stacked any

higher than 4 stacks of 30 (or 8 stacks of 15).

Board handlingThe boards should always be handled by two people and be

carried on their edge.

At no time should the boards be lifted flat by one of its ends.

When lifting a board, the long edge should be kept in contact

with the stack. Placocem weighs 13kg/m². All boards are

square edged.

Main instructions for UseCuttingGyproc Placocem Tile Backer Board can be cut using a

plasterboard saw or by scoring with a tungsten tipped blade

and snapping the board over a straight edge, as with

standard Gyproc plasterboard.

Fixing of SheetsGyproc Placocem Tile Backer Board should be placed on the

appropriate Gypframe components with the printed face

pointing outward, and then fixed using Placocem screws -

HB25 or HB41, positioned at 300mm centres, on all framing

members, and at no less than 10mm from the edge of the

board. Screw centres should be reduced to 200mm at

external corners.

Stud centres should be typically 600mm apart, however they

may need to be reduced depending on the application, such

as tiling where studs need to be fixed at 400mm centres.

Gyproc Placocem Tile Backer Board is suitable for use on the

following Gypframe studs:

• 70 S 60

• 92 S 60

• 70 S 15 post

• 92 S 10

• 146 S 60

• All studs in the Gypframe 'I' range

• Timber studs

10mm penetration is required when used on metal studs,

25mm is required for use on timber studs.

Always fix from the bottom of the partition upwards, as is

best practice.

2.4

Jointing BoardsThe joint between boards should be reinforced with the

Gyproc polyurethane joint glue:

• After fixing the first board, apply a continuous glue bead

of 3 to 4 mm diameter to the exposed edge of the board

• Position the next board, pushing the board edges together,

squeezing the glue bead.

• Use Placocem screws HB25 or HB41 to screw the board

in place.

After drying, the excess glue should be levelled with a knife

or a scraper.

Jointing with adjoining wallsA clearance of 4 to 5 mm should be systematically kept

between the Gyproc Placocem Tile Backer Boards and the

shell (floor, ceiling and walls) as well as between the Gyproc

Placocem Tile Backer Boards and any possible openings

(skylight frame, door frame etc.).

The jointing should be reinforced with a continuous line of

flexible elastomer mastic joiner.

Control and expansion jointsControl joints must be included in the partition every 6m

horizontally. Control joints must also be added to coincide

with existing movement joints in the structure.

The boards should be separated and the joint should be

completed either with a line of top grade elastomeric mastic

or with a Gyproc Control Joint. The control joint should

extend through to the finish applied on the Placocem board

i.e. tiling, paint etc…

In the case of an expansion joint of the building shell, the

typical solution that can be used is the one shown in Figure 1.

The solution shown in Figure 2 is designed to minimise the

loss in acoustic performance.

TilingCeramic tiles up to a maximum weight of 32 kg/m2 can be

applied to the surface of a Gyproc Placocem Tile Backer Board

which is already being used on a Gyproc partition or drylining

system. Please note that stud centres must be reduced to

400mm. Tiles must be applied directly to the board, using a

suitable tile adhesive, in accordance with the manufacturers

recommendations.

Consideration should be given to the use of a breather

membrane behind the Gyproc Placocem Tile Backer Boards in

areas with continuous moisture. The designer should be

consulted in such instances.

FinishingIf a plaster finish is required to a Gyproc Placocem Tile

Backer Board, Gyproc Thistlebond-it should be first applied

and allowed to dry. This should only be used in areas of

intermittent humidity.

PaintingIf painting directly on to Gyproc Placocem Tile Backer Board,

the following types of paints are suitable - vinyl, acrylic,

siloxane and glycerophtalic.

EnvironmentalGyproc plasterboard linings and associated accessories arenot suitable for use in areas subject to continuously damp orhumid conditions.

Fire protectionGyproc Cove and Cornice are plasterboard products and assuch are designated ‘materials of limited combustibility’within national Building Regulations. The surfaces achieve aClass 0 rating as a result of their performance when tested toBS476: Part 6: 1989 and Part 7: 1997.

Sound insulationAirtightness is essential for optimum sound insulation ofplasterboard building elements. Gyproc Cove, Cornice andStyletrims can assist in ensuring that linings meet their statedsound performance levels, since joints should be renderedimperforate during the bonding and jointing/makinggood process.

Maintaining performance levelsIf plasterboard is removed in order to facilitate theinstallation of Styletrims, fire resistance and sound insulationperformances will be affected. In most situations it is possibleto maintain performance levels by installing additionalplasterboard layers over and above the normal liningspecification. The lining should be extended sufficiently toprovide continuous support.

Please contact the Technical Sales Department for details andfor guidance generally where fire resistance is a requirement.

PERFORMANCE

Gyproc StyletrimsGyproc Styletrims can be used in conjunction with Gypframemetal studs, metal furring channels, GypLyner, and timberframing. Framing centres should not exceed 600mm. Verticalruns of Styletrim and all Styletrim joints should be supportedby framing members. Where these features occur betweennormal framing centres, additional members must beincorporated. Setting out should therefore be plannedbefore commencing fixing, both to reduce wastage and toallow the position of any extra framing to be determined.Gyproc Styletrims joints should always be backed up byplasterboard. Styletrim should never be installed so as to givedirect contact with framing members.

Gyproc Styletrim is used in conjunction with 12.5mm Gyprocplasterboard linings. Where Styletrim Reveal sections are tobe fitted, it is recommended that multi-layer linings are usedin order to increase rigidity and maintain the integrity of thesystem. Please refer to ‘Maintaining performancelevels’, earlier.

Gyproc Cove and CorniceGyproc Cove and Cornice can be installed to clean, dry andsound backgrounds using a suitable cove adhesive. Wherethe wall or ceiling has severe irregularities, the profiles can bemechanically fixed using non-rusting screws into plugs. Gapsalong the wall or ceiling edge of the profile can be filled witha suitable cove adhesive.
