oriented strand board (OSB) is an excellent choice for floor, wall and roof sheathing in residential and light
commercial construction applications. 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. Blue Ribbon OSB is edge coated to limit
absorption and pick-up of moisture.
