DryGuard

enhanced oriented strand board (OSB) is a multi-layered sub-floor product that has improved moisture resistance

throughout the panel plus a black edge seal to help reduce moisture absorption. This means protection from the elements

that helps avoid costly and time-consuming joint sanding. Each panel is third-party certified for quality and is rated for

Exposure 1 bond durability for protected applications and limited exposure during normal construction delays.
