5/8 in x 4 ft x 8 ft USG Securock ExoAir 430 Panel

Available in 1/2” and 5/8” thickness, the Securock® ExoAir® 430 Panel is a glass-mat, moisture- and mold-resistant lightweight gypsum panel, with a non-combustible core. The gypsum panel has been coated in a controlled environment with a synthetic vapor permeable air & water barrier membrane. The in-plant application provides a uniform membrane with superior bond resulting in consistent and predictable air and water barrier performance. The panel is a component of the Securock® ExoAir® 430 System, to be installed using Tremco® sealants and transition membranes to achieve air & water barrier continuity. The Panel can be exposed to UV up to 12 months.

Features

• In-plant application ensures membrane uniformity and adhesion
• Membrane is not climate-dependent and not susceptible to wash out
• Panel eliminates sheathing preparation in the field prior to the traditional field application of air barrier
• UV and weather resistance allow the panel to be installed, sealed and left exposed while interior construction begins
• Utilizes the lightest glass mat sheathing available – up to 15% lighter than other glass-mat sheathings
• Scores and snaps like traditional sheathing for easy installation
• Meets or exceeds the requirement of ASTM C1177
• Meets or exceed the requirement of ASTM E2178 and E2357
