                      Roof & Wall Sheathing

                      Weyerhaeuser sheathing installs in less time, with fewer callbacks

                      Our sheathing gives builders an advantage over other panels. The superior engineering of these panels protects against buckling, cupping, warping and sagging. To speed up installation, we've marked each panel with two-way nail lines applied vertically and horizontally at 16″ and 24″ spacing to eliminate the need for chalk lines.?
