Overview


Securock® ExoAir® 430 Air Barrier System

Securock® ExoAir® 430 Sheathing Panel includes a factory-applied air and water membrane designed to provide superior protection for the building envelope.

Available in ½” 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 he 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 and offers a 15-year panel warranty.

Main Features

Available in both ½” and 5/8” thicknesses, the Securock ExoAir 430 Panel 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
