VWFAIB Series Acrylic Vapor Barrier Tape is a high-strength acrylic sealing tape designed for the interior side of window and door openings in low-energy and highly airtight building envelopes. It provides a high vapor-resistance layer to help limit indoor moisture vapor transmission into the wall assembly.
As an internal vapor barrier sealing tape, VWFAIB helps protect insulation layers and structural components from condensation-related damage. It supports airtight detailing around window and door frames and is suitable for European low-energy window installation methods where the interior side requires reliable vapor control and air sealing. Customized configurations are available, including split release liners for easier installation and an optional narrow reverse-side adhesive strip for temporary frame pre-fixing.
