INSTALLATION 1. Install timber sole plate and framing members to end walls and ceiling. Ensure all framing is straight, plumb and true, and will provide a firm support for the plasterboards. 2.Fix intermediate vertical studs to the timber floor and ceiling plates at maximum 400mm centres for 9.5mm plasterboard, and at 600mm centres for 12.5mm and 15mm plasterboard. Framing should be arranged so as to avoid plasterboard widths of less than 300mm. Plasterboard edges must be supported at all openings, junctions and corners. All framing should provide a minimum bearing width for the plasterboard of not less than 38mm. Note: For all 900mm wide plasterboards, stud centres should be at 450mm. 3. Cut plasterboard 5mm to 8mm shorter than the floorto-ceiling height, butt firmly against the ceiling and fix with GTEC Drywall Nails at 150mm centres or GTEC High Thread screws at 300mm centres. Butt plasterboards lightly against each other, centring joints over the studs. With double layer boarding, the vertical joints should be staggered between layers. Sound insulation and High Performance Partitions If you require sound insulation or high performance party walls, greater performance can be achieved using Lafarge's range of performance plasterboard systems.
