System elements

Membrane:

• HDPE (high density polyethylene) with moulded 3 mm compression studs and bonded mesh lathing for applied plaster finish or plasterboard on adhesive dabs.
• Drainage volume: 1.56 L/m².
• Compression (maximum): 300 kN/m².
• On walls, suitable as backing for plasterboard on dabs or direct application of plaster
• Fixed to walls at 250 mm centres by drilling through membrane studs and inserting plaster plugs. Butt sheets and seal using tape.
• Suitable for ventilated application on walls above DPC level: Leave 20 mm gap to bottom of wall membrane and 10 mm gap to top. Insert profile strips into applied finishes or offset skirtings and covings.
• Suitable for applied coatings on walls: Use lightweight gypsum plasters or 1:1:6 cement:sand: lime render. 3 mm first coat to fill studs. 12 mm second coat. 3 mm skim coat. (Plaster or render specified elsewhere).
• Suitable for applied dry linings on walls. Apply bonding plaster in dabs to minimum thickness 8 mm and minimum coverage 50%.
• On floors, loose lay with compression studs downwards. Butt joint and seal using Overtape. Seal wall/ floor junction using corner detail trim.
• Floors can be overlaid using expanded polystyrene insulation with T&G floorboards, conventional screed or anhydrite screed. (Floorboards or screeds specified elsewhere).
