Fibreglass Matting
For standard GRP roofing systems 450gm and 600gm matting are the only two weights you’ll need to worry about. The type of fibreglass to use on a roof needs to be determined by surface area and foot traffic. Our recommendation and guidelines is that the only time you use 1 layer of 450gm is on roofs up to 5 square metres. For everything else its either 1 layer of 600gm or a dual layer of 450gm for foot traffic.
