4 T F E bgtechnical.enquiries@bpb.com Installation overview Run of lining The required cavity depth is determined, and chalk lines marked to floor and ceiling to indicate positioning of the Gypframe GL8 Track. Gypframe GL8 Track is fixed to perimeters using appropriate fixings. Vertical lines are marked on the wall at appropriate intervals to indicate Gypframe GL or GL9 Bracket fixing centres. Horizontal lines are marked at appropriate centres to determine individual bracket positions. Brackets are then fixed into position. Gypframe GL Lining Channels are friction-fitted into the track, extending if required. Bracket legs are bent forward and each leg fixed to the Gypframe GL Lining Channel. The protruding bracket legs are bent back to sit clear of the channel face. At internal angles, a Gypframe GL Lining Channel is positioned tight into the corner in order to provide support for the lining. Boards are fixed to all framing members. Openings Gypframe GL Lining Channel is positioned to slightly oversail the door opening on either side and fixed to the Gypframe GL8 Track at head and base. A section of Gypframe GL8 track is cut and bent to form the head of the opening. A short length of Gypframe GL Lining Channel is positioned midway above the opening to provide additional support. At window openings, Gyproc edge bead is fixed to the perimeter of the window frame to protect and restrain the lining. For full installation details, refer to the British Gypsum SiteBook or visit 33

8 T F E bgtechnical.enquiries@bpb.com Design Planning - key factors The depth of the cavity is determined by the positioning of the fixing brackets. Allow for a stand-off of 5mm - 75mm plus the lining thickness for Gypframe GL Brackets, and 5mm - 5mm plus the lining thickness for Gypframe GL9 Brackets. These stand-offs are sufficient to correct irregularities normally encountered in solid backgrounds. The stand-off will determine the lining dimension required at door and window reveals and soffits. Ceilings should be installed prior to installing GypLyner UNIVERSAL wall linings. Any abutting partitions should also be installed prior to drylining. Cavity barriers Building Regulations may require the provision of vertical cavity barriers to long runs of lining. Minimum.5mm plasterboard, screw-fixed to the web of Gypframe GL Lining Channel and the leg of the Gypframe GL or GL9 Bracket, will provide a satisfactory closer to flame or smoke. Refer to 7 Cavity fire barriers. When installing Gyproc ThermaLine laminates, the insulation should not be chased to accommodate services. PVC covered cables must not come into contact with polystyrene insulation. Suitable isolation methods such as conduit or capping should be used. Cabling Thermal performance Uncontrolled air movement through the drylining cavity can result in excessive heat loss from the building. The quoted U-values for GypLyner UNIVERSAL wall lining are based on a sealed cavity between the lining and the background. This is achieved in practice if the abutting elements and the background are well fitted, and junctions are sealed. When the perimeter of the cavity is to be sealed by the drylining contractor, the recommended method is to apply a continuous fillet / ribbon of Gyproc Dri-Wall Adhesive or Gyproc Sealant to the perimeter of the external wall and around any openings. The designer should also specify a method of restricting air movement around the perimeter of suspended timber floors, such as the provision of a flexible seal between the floor and walls. Central heating and waste pipes Good standards of thermal insulation can be achieved where Gyproc ThermaLine laminates are specified as the lining. There may, however, be a slight risk of pattern staining where temperature, humidity, and soiling conditions are extreme. Wall lining rigidity Brackets should be positioned equidistant at maximum 800mm vertical centres. Where there is a requirement for increased rigidity, these support centres should be reduced accordingly, although acoustic performance may be downgraded. Gypframe GL GypLyner Anchors are recommended for fixing brackets to the solid background. Soil pipes Refer to.5 Service installations. Lining durability Where added durability is required, substitute the face layer of board with Gyproc DuraLine of equivalent thickness. Services The cavity between the metal framework and the background facilitates the incorporation of services. Pipes and conduits should be fixed in position before installing the framing. Fixtures Lightweight fixtures can be made directly to the lining. Medium fixtures should be made to Gypframe 99 FC 50 Fixing Channel. For heavy fixtures additional support may need to be installed. Refer to..3 Robustness, Fixings into drywall systems. Board finishing Refer to 0 Finishing systems and decorative effects.
