Air-Bloc® All Weather STPE

Fluid Applied Vapor Permeable Air Barrier

A vapor permeable membrane with long-term UV resistance, Henry® Air-Bloc® All Weather STPE is a single-component, moisture cure Silyl Terminated Polyether (STPE) water-resistive air barrier. Featuring a high solids content and quick cure time, Air-Bloc® All Weather STPE can be applied with rain in the forecast, helping to reduce job-site weather delays.
