Library

Perm-A-Barrier® NPS (Non Permeable Sheet) is an NFPA 285 compliant, primerless self-adhering vapour impermeable air barrier membrane. Its specially designed adhesive eliminates the need to prime the surface of most construction materials, saving installation time and material cost. Perm-A-Barrier® NPS provides superior protection against the damaging effects of air and water ingress on building structures.

FEATURES AND BENEFITS
