Overview

Design versatility and performance

The PERM-A-BARRIER® portfolio offers both permeable and non-permeable solutions to meet the range of factors on a given project, including regional climate, wall design, compatibility with other materials, insulation placement and interior conditions.

Our newest air barrier PERM-A-BARRIER® NPS employs a primer-less, self-adhered application for easier installation that saves time and money on the job. Eliminates primer, often a hazardous chemical, from the site.
