PLYGOOD Ultra

PLYGOOD Ultra® is an extra strong extruded polystyrene (XPS) sheathing that makes homes more energy efficient. It offers superior insulation with four times the R-Value of 7/16'' OSB. With low moisture absorption and a perm rating greater than 1, it won’t swell or warp and is not subject to moisture-related damage and deterioration. A reinforcing scrim facer makes PLYGOOD Ultra extra durable and wind resistant up to 110 mph. Yet it’s lightweight and easy to install with staples, roofing nails, or plastic cap nails.
