3 T F E enquiries@gyproc.ie Boards INTRODUCTION Gypsum Industries manufactures an extensive range of plasterboards which, as part of a building system are designed to meet specific requirements relating to sound insulation and resistance to fire, moisture and impact. The tables below provide information on typical dimensions and edge profiles available. Reaction to Fire Plasterboard linings provide good fire protection owing to the unique behaviour of the non-combustible gypsum core 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 surfaces of Gyproc plasterboards and the exposed plasterboard surface of Gyproc thermal laminates are designated Class 0. Board weights All weights stated in the following tables are approximate. Board weights can vary. If the board weight is critical to the design, please contact the Technical Sales Department. Table 1 Classification Test Performance...

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 Building Regulations was amended in 2006 to also allow the Euroclass system to be used for demonstrating compliance with reaction to fire requirements. The following tables list the Euroclass reaction to fire classifications

15 T F E enquiries@gyproc.ie Jointing Air drying versus setting Setting Jointing compounds used for the joint filling stage(s) are usually setting products. Hardening is not dependent upon atmospheric humidity. Fillers that only harden by the setting process are hand applied and have low shrinkage. When a setting product is applied as a thin layer it may dryout before it has properly hardened. Setting materials are therefore unsuitable for the finishing application. Air-drying Jointing compounds used for the finishing application, by their very nature, are applied more thinly than fillers and so must have air-drying characteristics in order to harden sufficiently at feathered edges. Air drying materials can be applied by hand or machine using Gyproc Speed Tape tools. Air drying materials may be used as fillers but greater time needs to be allowed to permit the material to dry in depth, particularly in cold conditions. Air-drying materials should not be used for fixing corner tapes or beads.

17 T F E enquiries@gyproc.ie INSTALLATION OVERVIEW - Jointing

18 Jointing 2.2 Jointing Process Environmental Gyproc jointing materials are unsuitable for use in areas subject to continuously damp or humid conditions. Preparation 1. Boards should be securely fixed, with no steps between adjacent boards. 2. The correct fixings must be used and properly located with their heads just below the liner surface. Any protruding screw heads should be driven home using a hand screwdriver prior to spotting and jointing. 3. Jointing materials should not be applied to frozen surfaces and should not be used at, or subjected to, temperatures below 4ºC during setting or hardening. Joint reinforcement In a plasterboard system, suitable joint reinforcement is essential to minimise the risk of cracking along the joints, which then appears through the decoration. To achieve the objective of a smooth continuous crack-free surface, tapered edge plasterboard and Gyproc Paper Joint Tape are widely regarded as best practice when jointing or plastering. The tapered edges provide a recess for the joint treatment so allowing a flat, finished surface. At board joints, where cut edges or square edge boards occur, the joint treatment is inevitably raised above the board surface and is more difficult to conceal. In this situation the second and third stages are carried out using a Gyproc finishing product and joint treatment is feathered-out into the field of the board in order to conceal the joint as much as possible. Joint treatment has two essential components - the reinforcement and the jointing compound. Reinforcement is necessary where there is relative movement of adjacent boards. In practice movement of the background structure is possible and Gyproc Paper Joint Tape bedded into a jointing compound is recommended for the best crack resistance. Self-adhesive fibre tapes are an alternative, and can be easy and quick to install on flat joints. They are not, however, a direct substitute for Gyproc Paper Joint Tape, as tests have shown that Gyproc Paper Joint Tape provides superior resistance to cracking. In fire-rated applications Gyproc Paper Joint Tape must be used. Filling Tapered Edge Joints 1. A continuous thin band of Gyproc joint filling material should be applied to the trough of the tapered edge joints, making sure that no area is left uncovered. The required length of Gyproc Paper Joint Tape should be pressed into the band of filler. The tape should be firmly bedded with sufficient joint filler under the tape to ensure good adhesion. The filler should be brought flush with the surface of the plasterboard. 2. Immediately after the filler has set, or dried out fully, a second layer of filler should be applied over it. This should also be brought flush with the surface of the board. 3. Once the second application of jointing material has set or is fully dried out, apply a finishing coat of ProMix Filler & Finish. The finish coat should be feathered out into the field of the plasterboard. At all stages, any surplus material should be wiped from the edges of the joint with a moistened joint sponge, taking care not to disturb the main joint material. Square Edge Joints 1. A continuous thin band of Gyproc joint filling material should be applied over the joint, making sure that no area is left uncovered. The required length of Gyproc Paper Joint Tape should be pressed into the band of filler. The tape should be firmly bedded with sufficient joint filler under the tape to ensure good adhesion. Apply a 200mm wide continuous band of Gyproc joint filling material along both edges of the bedded Gyproc Paper Joint Tape. 2. When the first application of jointing material has set or is fully dried out, apply a second application of Gyproc joint filling material. This coat should be applied at 250mm wide along both edges of the Gyproc Paper Joint Tape. 3. Once the second application of jointing material has set or is fully dried out, apply a finishing coat of ProMix Filler & Finish. The finish coat should be feathered out into the field of the plasterboard. At all stages, any surplus material should be wiped from the edges of the joint with a moistened joint sponge, taking care not to disturb the main joint material. Nail / Screw Head Spotting The indentation should be filled with a layer of Gyproc joint filling material struck off level with the face of the board and allowed to set. After a second application of filler, the process is completed with an application of ProMix Filler& Finish. Gyproc Drywall Primer and Drywall Sealer Specially formulated for use on the surface for direct decoration of plasterboard. Applied in one application, after the jointing has dried, by brush or roller, it prepares the surface for paint and wallpaper decoration. For paperhanging it allows the paper to be wet-stripped when redecorating. For painting it primes, providing a consistent background for the first coat. Where a vapour check is required two coats of Gyproc Drywall Sealer can be used as an alternative to the Primer. A water vapour resistance of at least 15MNs/g is achieved. 66

19 T F E enquiries@gyproc.ie Jointing The Primer should be applied as soon as possible after board fixing is completed, particularly when decoration will be delayed. Coverage: Gyproc Drywall Primer: Approx.: 150m 2 /10 litres Gyproc Drywall Sealer Approx.: 80-90m 2 /10 litres for a two coat application 130m 2 for a one coat application Supplied in 10 litre containers Cut edges A similar finish to that obtained with tapered-edge boards can be obtained with cut-edge boards or a cut-edge and tapered-edge board. The cut edges should be lightly sanded to remove any paper burrs. The joint should be filled flush with the face of the board using a Gyproc joint filler and all the stages of jointing carried out as outlined above. Angle Reinforcement Plan of external angle showing position of Gyproc Corner Tape Plan of internal angle showing position of Jointing Tape Internal angles Gaps between the boards should be filled with a Gyproc joint filler. A thin layer of filler should be applied to both sides of the angle. The joint tape should be folded and pressed into the angle, making sure that air bubbles are removed. At this stage, the tape on both sides of the angle should be covered by a layer of filler. Sufficient joint filler should be left behind the tape to ensure good adhesion, and feathered out with the jointing sponge. Surplus material should be removed with the sponge. When this coat has dried a Gyproc joint finishing material should be applied to both sides of the angle and the edges feathered out with the jointing sponge. When the internal angles are formed at the junction of wallboard and plastered walls or ceilings, the above treatment should be carried out but it may be necessary to apply a narrow band of pva sealer to the plastered surfaces before applying joint filler. External angles When external angles are formed, any cut edges should be masked by a bound edge. If two cut edges occur together, the exposed edges should be given a brush coat of pva sealer. External angles should be reinforced with either Gyproc Corner Tape or Gyproc Angle Bead. Gyproc Corner Tape The tape should be cut to the length required and creased firmly at the angles to allow the steel strips to lie close to the wallboard surfaces. A 50mm wide band of Gyproc Joint Filler or Gyproc ProFill should be applied to each side of the angle. The tape should be pressed firmly on the corner, making sure that the arris of the folded tape is straight. Immediately after bedding the tape, a 100mm to 125mm band of Gyproc Joint Filler or Gyproc ProFill should be applied to both sides of the angle with the applicator. The edges should be feathered out with a moist sponge. After this coat of filler has set, a layer of finish should be applied and the edges again feathered out with the jointing sponge. Gyproc Angle Bead When maximum protection is required for the external angle, Gyproc Drywall Metal Angle Bead should be used. 25mm bands of Gyproc Joint Filler or Gyproc ProFill should be applied to both sides of the angle formed by the wallboard. The angle bead should be positioned on the joint filler with its wider flange covering the joint between the wallboards. It should be pressed firmly into place with the outer edges touching the wallboard surface. Material which has been squeezed through the holes and at the sides should be struck off flush and the remainder allowed to set. At this stage, the angle bead will tend to move if more joint filler is applied. If necessary one or two mechanical fixings may be used to ensure that the bead is not dislodged while the filler is setting. The nails should be removed after the filler has set. When the joint filler has set, another layer should be applied and feathered out. The surplus material should be removed with the sponge. After this layer of joint filler has set, a coat of finish should be applied to each side of the angle, 50mm beyond the edge of the joint filler

20 Ceramic tiling Ceramic tiling Tiles can be applied to drylined walls or the surface of lightweight partition systems to dado level or above. Tiling can be carried out in any type of building either in dry areas or in areas subject to intermittent moisture conditions. Typical applications include shower areas, toilets, bathrooms, cloakrooms and kitchens.

21 T F E enquiries@gyproc.ie DESIGN Health and Safety Safety Data Sheets for all Gypsum Industries are available to download from our website: or via the Technical Sales Department. Finishing Before tiling commences, any tapered edge joints included within the tiling area should be filled with tile adhesive. Other areas are finished as normal. Please refer to Section Finishing Coat Plasters, Section Jointing and Section Decorative effects. Ceramic tiling Detailing at junctions Designers must give consideration to the precautions necessary at junctions to ensure that moisture is not allowed to penetrate, collect, and cause problems or deterioration in walls and floors, e.g. at the base of walls where showers are specified with tiling to plasterboard, and at other junctions such as bath edges. Perimeter sealing Standard perimeter sealing methods around baths or shower trays are normally adequate. Caulking sealant can be used to form a fillet between the wall surface and the floor at the base of partition or wall lining to prevent any possible moisture being absorbed by the board core. Alternatively, the board ends can be protected by lengths of suitable channel or self-adhesive plastic tape. Tolerances The tolerance on the finished tile surface will reflect very accurately the standard of the background surface. This is particularly important on timber framed backgrounds. Therefore, the standard required of the finished tiled surface must also be applied to the timber framed wall. Boarding All partitions and wall linings should be complete. There should be no omissions to board linings, e.g. behind baths. Timber stud external walls or partitions Where ceramic tiling is specified, designers should ensure that the timber is of sufficient dimensions to give a stable base for the additional loading. Movement joints Reference should be made to all relevant standards, including ceramic tiling standards

26 Placocem Introduction Characteristics Gyproc 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. Applications Gyproc 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 colour Grey - Face. Grey - Reverse. Board printing Face - printed (product name and board thickness) Edge - blank Reverse - blank Board performance Moisture resistance Gyproc Placocem Tile Backer Board offers excellent moisture resistance properties, resulting in less than 180 g/m 2 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 protection Gyproc Placocem Tile Backer Board achieves an A2- s1, d0 Reaction to fire classification. Fire resistance Performances 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 insulation The 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 loads Loads 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.

Board handling The 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. Gyproc Placocem Tile Backer Board is equivalent to Type I plasterboard in accordance with the EN 520 surface hardness test. Duty rating The 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. Temperature Gyproc Placocem Tile Backer Board is not suitable for use in temperatures above 90ºC. Effect of condensation Gyproc 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 storage The 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). Main instructions for Use Cutting Gyproc 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 Sheets Gyproc 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 S S 15 post 92 S 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. 2.4 Always fix from the bottom of the partition upwards, as is best practice. 75

28 Placocem Jointing Boards The 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 walls A 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.). Figure 1 - Basic solution Gyproc Control Joint or a top grade elastomeric mastic Gyproc Control Joint or a top grade elastomeric mastic Isover Acoustic Roll The jointing should be reinforced with a continuous line of flexible elastomer mastic joiner. Figure 2 - Solution with acoustic treatment The solution shown in Figure 2 is designed to minimise the loss in acoustic performance. Tiling Ceramic tiles up to a maximum weight of 32 kg/m 2 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. Control and expansion joints Control 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. 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. Finishing If 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. Painting If painting directly on to Gyproc Placocem Tile Backer Board, the following types of paints are suitable - vinyl, acrylic, siloxane and glycerophtalic

32 Decorative effects PERFORMANCE Environmental Gyproc plasterboard linings and associated accessories are not suitable for use in areas subject to continuously damp or humid conditions. Fire protection Gyproc Cove and Cornice are plasterboard products and as such are designated materials of limited combustibility within national Building Regulations. The surfaces achieve a Class 0 rating as a result of their performance when tested to BS476: Part 6: 1989 and Part 7: Sound insulation Airtightness is essential for optimum sound insulation of plasterboard building elements. Gyproc Cove, Cornice and Styletrims can assist in ensuring that linings meet their stated sound performance levels, since joints should be rendered imperforate during the bonding and jointing/making good process. Maintaining performance levels If plasterboard is removed in order to facilitate the installation of Styletrims, fire resistance and sound insulation performances will be affected. In most situations it is possible to maintain performance levels by installing additional plasterboard layers over and above the normal lining specification. The lining should be extended sufficiently to provide continuous support. Please contact the Technical Sales Department for details and for guidance generally where fire resistance is a requirement. DESIGN Gyproc Styletrims Gyproc Styletrims can be used in conjunction with Gypframe metal studs, metal furring channels, GypLyner, and timber framing. Framing centres should not exceed 600mm. Vertical runs of Styletrim and all Styletrim joints should be supported by framing members. Where these features occur between normal framing centres, additional members must be incorporated. Setting out should therefore be planned before commencing fixing, both to reduce wastage and to allow the position of any extra framing to be determined. Gyproc Styletrims joints should always be backed up by plasterboard. Styletrim should never be installed so as to give direct contact with framing members. Gyproc Styletrim is used in conjunction with 12.5mm Gyproc plasterboard linings. Where Styletrim Reveal sections are to be fitted, it is recommended that multi-layer linings are used in order to increase rigidity and maintain the integrity of the system. Please refer to Maintaining performance levels, earlier. Gyproc Cove and Cornice Gyproc Cove and Cornice can be installed to clean, dry and sound backgrounds using a suitable cove adhesive. Where the wall or ceiling has severe irregularities, the profiles can be mechanically fixed using non-rusting screws into plugs. Gaps along the wall or ceiling edge of the profile can be filled with a suitable cove adhesive
