Technical Features
- Self-adhering membrane: Bonds directly to substrate without additional adhesives, reducing installation time and labor.
- Dual air and vapor barrier: Simultaneously blocks air infiltration and vapor transmission, providing a combined weatherproofing solution in a single application layer.
- Permanent waterproofing seal: Forms a continuous, long-term water-resistant barrier around rough openings, protecting the building envelope against moisture intrusion.
- Tough-faced construction: Durable facing resists tearing and puncture during handling and installation, maintaining membrane integrity at door and window perimeters.
- 4 in. x 75 ft. roll format: Roll dimensions are sized to efficiently cover standard rough opening flanges and sill pans with minimal overlapping cuts.
Applications
- Flashing around door and window rough openings in residential and commercial construction.
- Air and vapor sealing at wall penetrations where doors and windows interface with the building envelope.
- Waterproofing membrane application at sill pans, jambs, and headers to prevent bulk water entry and condensation-related damage.
