USG Corporation and Tremco Commercial Sealants & Waterproofing collaborated to create Securock ExoAir 430 System – a new advancement in air barrier installation to the construction industry.

In a controlled environment, the air/water barrier coating is applied to a glass-mat faced, moisture and mold-resistant gypsum sheathing panel.

This process results in a uniform membrane with superior bond to the substrate. The system, comprised of the panel and detailing components, simplifies the installation process and eliminates many traditional application challenges like weather impact, material waste and performance variances, while improving jobsite scheduling concerns.
