High quality Vapour Barrier Tape and AVCL Tape products

Vapour Barrier and AVCL Tapes

Vapour barrier tape may help seal air and vapour control layer systems when used with compatible materials. It can support a continuous barrier across laps, edges, junctions and abutments. Contractors often use these tapes with suitable membranes to help reduce air and vapour leakage through the building envelope.

Tapes for Membrane Detailing

BaseTec supplies vapour barrier tapes and AVCL tape options for specialist construction work. The range includes selected Visqueen tapes, with options for lap sealing, edge sealing and bonding membranes to suitable substrates. These may help contractors complete clean and reliable membrane details when installed as part of an appropriate system.

Choosing the Right Tape

The right tape depends on the membrane, substrate, fixing method and required system performance. Always check compatibility with the chosen AVCL or vapour barrier system before installation. Follow the manufacturer’s guidance to help protect the performance of the finished system.

Frequently Asked Questions About Vapour Barrier Tape and AVCL Tape

What are vapour barrier and AVCL tapes used for?

Vapour barrier and AVCL tapes are commonly used to seal laps, edges, junctions and abutments in air and vapour control layer systems. They may help reduce air and vapour leakage when used with compatible membranes and installed in line with the manufacturer’s guidance.

How do I choose the right vapour barrier tape?

The right vapour barrier tape depends on the membrane, substrate, fixing method and required system performance. Always check compatibility with the chosen AVCL or vapour barrier system before installation, especially where airtightness or moisture control is critical.

Can AVCL tapes be used with any membrane?

AVCL tapes should only be used with compatible membranes and substrates. Compatibility can vary by product, surface condition and installation environment. Check the product data sheet and manufacturer’s guidance before use to avoid affecting system performance.

Where are vapour barrier and AVCL tapes usually applied?

Vapour barrier and AVCL tapes are usually applied around membrane laps, penetrations, edges, junctions and abutments. They may also be used for bonding membranes to suitable substrates, depending on the product. Seek technical advice for complex or safety-critical applications.
