Product Data Sheet

 

Description

Perm-a-Barrier NPL 10 is a fluid applied, one component, latex-based membrane that cures to form a resilient, monolithic, fully-bonded elastomeric sheet when applied to construction surfaces. Designed to satisfy the requirements of fire-rated assemblies, Perm-A-Barrier NPL 10 can be included in a wide variety of NFPA 285 compliant wall designs. Perm-A-Barrier NPL 10 membrane is impermeable and provides superior protection against the damaging effects of air and water vapor ingress on building structures. The product creates a solid barrier against air and vapor infiltration and exfiltration which minimizes energy loss from the structure and associated moisture related issues. Also impermeable to liquid water, Perm-A-Barrier NPL 10 acts as a water drainage plane.

Advantages

  • Fire Resistant—meets NFPA 285 as part of various wall assemblies
  • Plasticizer, Phthalate and Halogen-free—safe and environmentally-friendly
  • Air tight—protects against air passage and associated energy losses. Meets ASTM E2357 standard
  • Vapor impermeable—protects against the passage of water vapor.
  • Single component—fast and easy application with simple spray equipment
  • Fully bonded—transmits wind loads directly to the substrate
  • Seamless—continuous membrane with no laps
  • Strong adhesion to common construction substrates such as block, concrete, gypsum sheathing and metal
  • Compatible with Grace Perm-A-Barrier Flashing Systems

Principal Applications

Air and vapor barrier for new and remedial commercial applications:

  • Concrete block walls with brick veneer or pre-formed cladding panels
  • Steel or wood stud walls with exterior gypsum sheathing, brick veneer or preformed panels, plywood and OSB
