Polyglass VertiWrap VPL is a vapor permeable air barrier coating designed to create a continuous barrier against uncontrolled air movement while still allowing moisture vapor to escape. This helps protect wall assemblies from trapped moisture, reducing the risk of mold, rot, and long-term structural damage.
Built with SWIFTSET Technology, this fluid-applied membrane delivers faster curing times and more consistent performance across a range of jobsite conditions. It forms a seamless, monolithic barrier that improves energy efficiency while maintaining proper wall assembly breathability.
The 5 gallon pail is ideal for detail work, penetrations, and smaller applications where a full drum is not required. This helps reduce material waste and improve jobsite efficiency.
