Description
AIR-SHIELD is a self-adhering air, vapor, and moisture barrier made from 40-mil rubberized asphalt membrane laminated to cross-laminated film. It forms a tough, flexible seal that won’t shrink, sag, or dry out.
- Self-adhering air/vapor and liquid moisture barrier
- 40 mils thick rubberized asphalt membrane
- Roll-applied, no open flame needed
- Strong adhesion and puncture resistance
- Flexible at minimum 40F application temperature
Features
- Low permeability prevents air and moisture transmission
- Provides complete above-grade air, vapor, and water barrier
- Controlled thickness membrane ideal for air barrier applications
- Remains flexible when surface mounted
- Excellent resistance to punctures during installation
