GoBoard is engineered and tested for strength and durability, yet can be cut right where it’s installed using a utility knife. Plus, it's up to 80% lighter than traditional boards. Installation time is reduced because waterproofing is built-in, eliminating extra steps since only board joints and fastener locations need to be sealed.

Perma “R” Brace SIB is a lightweight, 4-in-1 structural sheathing solution that provides four layers of enforced protection against water, moisture vapor, mold, and more. All the benefits of our Perma “R” Brace with the added value of our stable, R5 per nominal inch GPS (Graphite Polystyrene) rigid foam. 

Perma “R” Brace incorporates an air and moisture barrier on both sides of our light-weight structural sheathing for a cost-saving replacement for OSB. Saving on labor and material costs, our sheathing line offers a better alternative to OSB and other expensive, heavier panel system competitors.
