The Henry Company recently introduced its Henry Air-Bloc All Weather STPE Fluid-Applied Vapor Permeable Air Barrier. The fluid-applied, elastomeric membrane is resistant to ultraviolet (UV) rays and fire, and it is designed to provide a vapor-permeable, water-resistive air barrier when applied to above-grade wall assemblies.

The air barrier can be applied at sub-freezing temperatures and can withstand rain within 30 minutes of application, according to the manufacturer.

Rubber-Like Membrane

The single-component, moisture-cured silyl terminated polyether (STPE) forms a durable monolithic rubber-like membrane that resists air leakage, water penetration, and long-term weathering. It can be sprayed, rolled, or brushed on in one coat, and the membrane allows walls to breathe and dry.

“Specifying the Henry Air-Bloc All Weather STPE has many pluses that give extraordinary project flexibility to both the designer and the installer,” said Christian Nolte, senior vice president of marketing and product management. “It offers flexibility for designs that call for permanent UV exposure under open-joint cladding.”

“And, for the installer, this product is easy-to-spray with excellent adhesion, even in temperatures as low as 10 °F [-12 °C] or on damp surfaces in high-humidity environments,” Nolte added. “A major advantage: this air barrier is truly rain-ready. It can be applied just before precipitation arrives, cures quickly, and won’t wash off after the rain begins, so there’s less impact on the installation schedule.”

Fluid-Applied Portfolio

In addition to its UV-resistant, rain-ready, and adhesive properties, the air barrier integrates with Henry flashing and accessories to form a complete wall system, which meets industry standards for high performance.

The air barrier is part of the Henry Air-Bloc portfolio of fluid-applied air barriers. Henry also provides a portfolio of Blueskin self-adhered water resistive air barrier options, manufactured to a precise thickness to help ensure uniform performance and create a continuous membrane upon installation.

Henry offers its Air-Bloc fluid-applied and Blueskin self-adhered air barrier lines in a range of vapor impermeable and vapor permeable options to accommodate every climate and substrate, delivering greater flexibility across a wide range of projects.
