Grip-Rite weather resistive barriers are made of a durable high density polyethylene woven substrate that possesses very high tensile strength that resists tearing that results from high wind exposure. Superior UV treatment allows exposure for over six months without deterioration. Grip-Rite House-Wrap and Commercial Grade weather resistive barriers are coated on both sides with LDPE. Grip-Rite House-Wrap-E and LWE are coated on one side. All Grip-Rite WRBs are micro-perforated to allow breathing.
