Air Barrier

Today the building science community and industry professionals understand the cause and effect of proper building enclosure performance on the longevity of the building, tenant and owner comfort, energy consumption, internal air quality, and both initial construction budget and operating costs.

Two approaches for building envelope enclosure are commonly utilized in today’s construction industry – vapour open and vapour closed assemblies, utilizing sheet membrane or liquid applied materials. Industry consultants and building professionals are increasingly using a holistic enclosure approach to address a common technical challenge, which is compatibility of materials and assemblies.

Naturaseal offers both high and low permeability air-barrier solutions. The Air Barrier NS-A250-HP is a high permeability formulation designed for wooden structures, foam, insulation and fibre board. It is often seen in residential homes and townhomes. The Air Barrier NS-A250-LP is a low permeability formulation designed for commercial application in wood, insulation, foam, and particularly in concrete walls, and cedar blocks.

Air Barrier NS-A250 is an elastomeric coating for industrial, commercial and residential air barrier applications. Air Barrier NS-A250 is water-proof, weather and vapour resistant, UV stable, eco-friendly, and safe to use. With its unsurpassed ability to expand and contract, it can easily withstand all weather conditions. Both the Air Barrier NS-A250-HP and Air Barrier NS-A250-LP act as a rain screen, with a seamless and monolithic membrane.

The application utilizes cold liquid applied, adhesion and instant cure technology, with an easy ability to bridge building settlement conditions as there are no seams of laps conditions. During sequencing or construction delays this air barrier can be exposed for long periods of time.
