KARNAK, an industry-leading manufacturer of reflective coatings, sealants and cements, recently announced the launch of K-NRG Seal VP, a high-performance vapor-permeable air barrier for above-grade wall application.   

K-NRG Seal VP expands KARNAK offerings, which include roofing, damp-proofing and waterproofing products; fabrics and repair tapes; caulks, sealant and flooring products; and elastomeric products.  

 “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.

K-NRG Seal VP’s 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. 

KARNAK’s 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. 

For building owners, K-NRG Seal VP’s benefits assure a fire-safe, long-term, sustainable air barrier solution. K-NRG Seal VP is designed to improve building occupant comfort, improve acoustical isolation, help reduce greenhouse gas formation (lessening environmental impact), help reduce heating and cooling costs, and help improve indoor air quality. It may also reduce building enclosure moisture problems.  

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.
