It’s a one-of-a-kind structural roof and wall system with a built-in energy-efficient barrier that keeps moisture out and reduces air leakage, while still allowing panels to properly dry. Plus, it installs in two easy steps: 1. Install the panels, 2. Tape the seams. Fewer steps result in 40% faster installation when compared to traditional housewrap and felt.

Plywood is chemically pressure-treated to reduce the spread of flames and generation of smoke. In the event of a fire, this plywood will not spread fire and develops less smoke. Plywood may be substituted for materials classified as non-combustible in certain building types designed by the model building codes. This plywood can be painted or stained just as untreated wood, but flammability of the finish should be considered. This plywood is in intended for interior use only and should be protected against direct moisture, precipitation or regular condensation.
