Airtightness tapes designed to seal joints, reduce air leakage and improve energy efficiency in old and new buildings. We stock high quality tapes suitable for retrofit and new construction projects. Buy now

Designed for airtight sealing of membrane overlaps, window frames, door frames, junctions and service holes, airtightness tapes help to reduce uncontrolled air leakage and improve overall building performance.

Our range of tapes play a critical role in enhancing thermal efficiency, reducing heat loss through convection, and supporting compliance with energy performance standards such as Passivhaus principles and UK Building Regulations. They are typically compatible with vapour control layers (VCLs), breather membranes, OSB, timber framing, masonry, and many common construction substrates.

Pro Clima airtightness tapes are engineered with high-performance adhesive systems that deliver durable, long-term bonds. Products such as Pro Clima Tescon Vana is widely specified due to it's strength, durability & longevity. The multi-layer construction of the tape allows for controlled vapour diffusion while maintaining permanent airtight integrity, even under movement or seasonal structural changes.

Ideal for both new build solid wall, timber frame and retrofit applications, our airtightness tapes provide reliable solutions for achieving airtightness across the building sector, helping to improve comfort, reduce energy demand, and protect building fabric longevity.
