Quick Overview
BlockFlashing is a self-adhered, non-asphaltic, air, water, and vapor barrier flashing.Self-Adhered, Non-Asphaltic, Air, Water, and Vapor Barrier Flashing
- Non-Asphaltic product
- Impermeable to air, moisture vapor, and water
- Use as a rough opening flashing or transition flashing
- Aggressive pressure-sensitive adhesive
- No primer required
- 12 month UV and weather exposure
- AAMA 711-13 compliant
- Application temperature 20°F (-6.6°C) and rising
- Durable, tear resistant, and flexible at low temperatures
- Zero VOCs
- Multi-layer elastomeric film seals around nails and staples to prevent moisture intrusion.
- Compatible with many building sealants: no adverse reaction with synthetic rubber, butyl, polyurethane, silicone and silane terminated hybrid sealants.
