Product Details

Product #HE029

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. Its hydrophobic nature also means it won’t wash off in the rain. Plus, it can be spray-, roller- or brush-applied. Permanent UV exposure behind open-joint cladding offers design flexibility. Can be used as a liquid flashing when Air-Bloc All Weather STPE is the primary membrane, resulting in quicker air barrier system installation.

Vertical and lateral flame propagation: meets NFPA 285 Exception #2 per ASTM E1354 and ASTM E84

Usage:

Can be used as a liquid flashing when Air-Bloc All Weather STPE is the primary membrane, resulting in quicker air barrier system installation (Passes AMAA 714-19. See Installation Manual and Technical Data Sheet for details.)
