The Lanyon and LeCompte Strapped R5.0 Insulation system consist of 6 components, GrayCol Top, Middle, and Bottom fiberglass thermally broken carrier channels, 100mm thick H grade Polystyrene Insulation, Specially formulated Bostik Safe Stud Adhesive, and standard 10mm Gib board. All Electrical and Plumbing services are installed in the 20mm cavity between the concrete precast wall an strapping system before installation. The Graycol bottom carrier channel is glued and nail fired at 600 centres to the floor slab, the first sheet of 100mm H grade polystyrene is then installed into this channel. The middle section rail is then installed onto the top of the bottom sheet of H grade polystyrene. Bostik Safe Stud adhesive is applied to the back of the rail, the rail is then fixed to the precast wall using 10mm nails fired at 600 centres.
If a window is present the H grade polystyrene is cut around the opening with any gap foam filled after installation. The GrayCol Top Channel is then fitted to the top of the H grade polystyrene top sheet and the sheet is lifted and inserted into the middle section rail. This sheet is then rotated into place until seated against the precast wall. The GrayCol Top Channel is then glued to the Concrete Precast Wall and top fixed to the ceiling battens using screws at 600 centres. In the case where any wall hung fittings are present the H grade polystyrene is routed out and a backing sheet of 18mm plywood is fixed. 10mm Gib board is then glued and screwed to the GrayCol Bottom, Middle, and Top fiberglass carrier channels as per Gib fixing instructions.
