Grip-Rite weather resistive barriers are made of a durable high density polyethylene woven substrate that possesses very high tensile strength that resists the 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 is coated on one side.
