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.
