Exterra offers a high-performance GPS core that is laminated on both sides with a precision-perforated film.

Features

• BREATHABLE: 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.
