New Liquid-Applied Air Barrier Now Offered


Coatings and sealants manufacturer Karnak (Clark, New Jersey) recently launched its new high-performance vapor-permeable air barrier for above-grade application.

The K-NRG Seal VP is a seamless elastomeric membrane that works to seal the building envelope, preventing air passage while allowing vapor permeability, the company says, adding that it’s designed to aid in energy efficiency and mold resistance.

“We are proud to launch an air barrier product that offers long-term sustainability and durability in building envelope protection,” said Chris Salazar, Chief Operating Officer of KARNAK.

“From architect or specifier, to installer, to building owner and building occupant, K-NRG Seal VP is a product that will benefit everyone.”

The company notes that the liquid-applied, fire-rated barrier has been evaluated by the Air Barrier Association of America, meeting the highest industry standards. The product also passes the NFPA 285 Fire Test, which makes it compliant with IBC 2012. It also exceeds ASTM E2357 and ASTM E2178.

The spray-applied K-NRG Seal VP adheres to most wall construction materials, the company said, including exterior gypsum boards, CMU, stone, wood, metal, and damp or dry concrete.
