SYSTEM COMPONENTS
WIRE GUARD
EXPOL Wireguard is a waxed paper strip used to separate exposed electrical cables from EXPOL insulation. EPS in some cases reacts with the plasticiser and degrades the elastic properties of some electrical cables over a prolonged period.
STYROFIX CONSTRUCTION ADHESIVE
EXPOL supplies a low solvent glue designed to adhere polystyrene to most surfaces. EXPOL Platinum Board can be glued in place using this adhesive.
Installation requirements
Install the polystyrene sheets once the polythene DPM has been laid. Place the polystyrene sheets on top of the polythene DPM and butt together. Do not place the polystyrene under any footings or thickenings. Cut holes in the polystyrene with a sharp knife to accommodate any services. Lay reinforcing steel mesh over the polystyrene on mesh chairs.
