Frequently Asked Questions

What are airtightness products used for?

Airtightness products are used to help seal gaps, joints and penetrations in building and ventilation projects. They can support better control of air leakage around ductwork, windows, membranes and construction details.
Why is airtightness important for ventilation systems?

Airtightness helps reduce unwanted air leakage, which can support better ventilation performance and overall building efficiency. In projects using MVHR, airtightness is especially important because the system is designed to work best in a controlled building envelope.
Do the same airtightness products work for timber frame and masonry builds?

Some products are suitable for both, while others are designed for specific substrates or construction methods. Always check product compatibility before installation.
What can be done to fix a failed air pressure test?

Air leaks should be identified and sealed at common leakage points such as service penetrations, junctions, windows, doors and membrane connections before retesting.
What products are used to achieve an airtight building envelope?

Common airtightness products include membranes, tapes, sealants, grommets, collars and specialist products for sealing service penetrations and construction junctions.
