KARNAK Launches Sustainable Membrane Sealant Air Barrier Product

Posted By ASC, Wednesday, October 18, 2017

KARNAK has released a new vapor-permeable air barrier product for building envelope protection. The makers of damp and waterproofing products say that the new product, K-NRG Seal VP, is an elastomeric membrane seal which will improve buildings’ energy efficiency while enhancing mold resistance.

 

The product is applied as a spray in liquid form and bonds with the majority of wall construction materials. These include wood, concrete, stone, gypsum boards, and CMU. No specialized equipment is required for its application. The vapor-permeable barrier has undergone and passed the NFPA 285 Fire Test and exceeds currents ASTM standards.

 

Apart from the properties already mentioned, the product is intended to provide additional acoustical isolation and may contribute to improving indoor air quality while reducing the need for supplementary heating and cooling. As such, it can contribute to the achievement of LEED certification.

When used in combination with other KARNAK sealants, K-NRG Seal VP forms part of a complete vapor-permeable air-barrier system.
