Sheet Membrane Vapor Permeable Air Barrier
AIR-SHIELD SMP is a self-adhesive, vapor permeable, air/liquid moisture barrier that is designed to be fully bonded to the substrate without the use of an adhesive or primer.
AIR-SHIELD SMP has been specifically formulated to act as an air and liquid moisture barrier, allowing vapor to pass through it. It may be applied to most common surfaces and integrated into various wall assemblies. AIR-SHIELD SMP is suitable for both new construction and retrofit applications.
FEATURES/BENEFITS:
- When properly applied, helps reduce air and moisture intrusion
- Bonds easily and securely to a variety of building materials – no primer required
- Excellent adhesion – remains firmly bonded to the substrate
- High vapor permeability – allows the transmission of moisture through porous building materials
- Highly flexible and bridges cracks
- Can be left exposed to UV for a maximum of 90 days
- Tough membrane helps resist punctures during installation
- Can be installed in a wide range of temperatures
AIR-SHIELD SMP exhibits excellent resistance to air leakage and liquid intrusion, while at the same time allows vapor to readily pass through to allow the wall assembly to dry.
