CHOOSING THE RIGHT WEIGHT OF CSM (CHOPPED STRAND MAT) FIBREGLASS MATTING
(Article from Fixmyroof)
You may find all sorts of suggestions from fibreglass suppliers of what weight of fibreglass CSM (CHOPPED STRAND MAT) mat to use on your roof. Some don’t say, some say 450g, some 600g or others say double laminate 300g or 450g. In the end it turns into a “mines bigger then yours” contest devoid of all logic and reason. The simple truth is there are guessing because they want the best for you but they haven’t seen your roof, it’s size, it’s shape or how well it’s constructed. Some fibreglass suppliers are just suppliers and only that, and some have a history of fibreglassing roofs and can speak from real experience. Here are my suggestions, feel free to use them, ignore them, or improve on them.
