KARNAK launches K-NRG Seal VP

KARNAK launches K-NRG Seal VPKARNAK launches K-NRG Seal VP, a high-performance vapor-permeable air barrier for above-grade wall application. The seamless elastomeric membrane seals the building envelope, preventing air passage while allowing vapor permeability. The product is designed to provide the building envelope with superior energy efficiency and mold resistance.

According to the manufacturer, the new liquid-applied, fire-rated vapor-permeable air barrier, evaluated by the Air Barrier Association of America (ABAA), meets the highest industry standards. K-NRG Seal VP has been tested by UL Laboratories and passes NFPA 285 Fire Test, making it compliant with IBC 2012 and allowing flexibility in choice of insulating materials. It also exceeds ASTM E2357 and ASTM E2178.

The liquid-applied air barrier strongly adheres to most wall construction materials, including exterior gypsum boards, CMU, stone, wood, metal, and damp or dry concrete, making it ideal for multi-story applications. K-NRG Seal VP requires easy spray application using standard spray equipment. When combined with KARNAK sealants and accessories, K-NRG Seal VP forms a complete vapor-permeable wall air-barrier system.

According to the company, With K-NRG Seal VP, building owners can reduce energy costs, improve overall building functionality and safety, as well as contribute to potential LEED certification. “We are proud to launch an air barrier product that offers long-term sustainability and durability in building envelope protection. From architect or specifier, to installer, to building owner and building occupant, K-NRG Seal VP is a product that will benefit everyone,” said Chris Salazar, Chief Operating Officer of KARNAK.
