Drywood Products.

Providing a structural sheathing with a laminated ice and water barrier, Drywood roof and wall panels eliminate the need for felt paper, ice and water shield, and an air infiltration barrier, says the firm. A seam tape provides moisture resistance at abutting edges, valleys, roof/wall intersections, and ridges. Drywood can be used under shingles, slate, tiles, and wall veneers and siding. 309.303.0514. www.drywoodproducts.com.
