Why Use LP FlameBlock Instead Of Other Products?
Unlike chemical treatments used to create products such as FRT plywood, the Pyrotite® coating on LP OSB sheathing causes no initial or long-term loss of structural strength. LP FlameBlock Sheathing does not require special handling of scrap disposal.
Lighter and stronger than gypsum wallboard, using LP FlameBlock Sheathing saves time and money over a structural sheathing plus gypsum approach. It’s Exposure 1 rated, so it can withstand weather during normal construction delays.
