Known as Separator Board, this brand name, 1/2" thick, rigid foam roof recover board is lightweight but sturdy. It's a flexible option for recover or metal retrofitting, acts as a layer of protection between new membrane and existing roof surface issues, and provides a clean base for new waterproofing membrane. Designed for commercial roofing, it's also great for residential applications, and can be used as a backdrop, a temporary wall, or for art installations.
