PERM-A-BARRIER® NPS Air Barrier

Impermeable self-adhering air and vapor barrier membrane

Overview

Protecting buildings from the damaging effects of the elements doesn’t have to be so labor-intensive. PERM-A-BARRIER® NPS air barrier safeguards against the ravages of the elements, without the need to use primer.

What is PERM-A-BARRIER® NPS?

PERM-A-BARRIER® NPS membrane minimizes air and water vapor flow through a building’s exterior, minimizing premature deterioration of the building’s envelope and improving its energy efficiency. Even better, this primerless impermeable air barrier membrane saves time and money. In field trials, it proved to be up to 35% faster to install than comparable membranes that require a primer.

Application

It’s applied the same way as any other barrier membrane, only without having to use primer. And since there’s no primer needed, you’ll eliminate cleanup time and additional material costs, such as primer, rollers and cleaning supplies—resulting in a significant cost savings over alternative solutions.
