Our proprietary perforation technology makes Exterra breathable (up to a thickness of 2") and allows vapor to escape, helping to keep the wall healthy and dry.
Water Resistive
Exterra is also a water-resistive barrier which makes it truly unique. Exterra keeps water to the exterior without the need for additional house wrap.
Energy Efficient
Continuous GPS insulation creates a thermal break and eliminates the energy loss from thermal bridging in the wall assembly.
Durable and flexible
Exterra is also durable, yet flexible, and easily conforms to radius walls without needed time consuming field cuts.
