Foilboard® GREEN rigid insulation panels should be installed between the wall girts and to the underside of the roof batterns/purlins.
Mark the measurements out on the Foilboard® GREEN rigid insulation panel, using the gridlines as a guide. Using a straight edge and a sharp blade/knife, cut the rigid panel to size (width ways will ensure less wastage).
Use Foilboard® spacer blocks to maintain an airspace between the Foilboard® and the metal sheeting to increase insulation performance.
Fasten the insulation panel to the roof batterns/purlins with Foilboard® fasteners using approx. 5-6 per m2. Use either a hammer or a drill as required.
Tape any penetrations joints and gaps using Foilboard® GREEN tape minimise hot/cold air transfer.
Use Foilboard® Ultra Fasteners for GREEN 20 and GREEN 25.
