Grip-Rite weather resistive barriers are made of a durable high-density polyethylene woven substrate that possesses a 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.
