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 job site.

Tried and tested for high performance with code compliance

Most products in the PERM-A-BARRIER® portfolio meet or exceed all ASTM, ABAA and NFPA building code standards. In addition, PERM-A-BARRIER® solutions have been tried, tested and proven across thousands of projects worldwide.

Expert field technical support

Our technical experts frequently provide direct consultation throughout the design, product selection and installation process. In addition to project-specific support, we provide both classroom and hands-on applicator training to ensure that our PERM-A-BARRIER® products are installed correctly and perform as designed, protecting the structure for years to come. Able to instruct applicators on the installation of sheet membranes and proper spray techniques, our field technicians advise on the proper sequencing and use of materials within these flexible systems. You can consult in-product compatibility and assembly techniques for a completely watertight and airtight system. Our technicians offer advice on detailing, sequencing, efficient assembly techniques and labor-saving tips.
