Pro Clima Duplex is a versatile double-sided adhesive tape designed to deliver reliable airtight, windtight and moisture-resistant sealing across a wide range of membrane applications.

Suitable for both internal and external use, it provides a fast, clean, and highly effective way to seal overlaps and connect membranes to smooth structural surfaces.

Its double-sided design allows for discreet, “invisible” bonding between membrane layers, creating a neat professional finish while maintaining a durable airtight and weatherproof seal.

This makes it ideal for roof, wall, floor and ceiling membrane installations where long-term performance is essential.

Duplex is particularly effective for bonding membranes to hard smooth materials such as steel, timber, concrete, plaster and rigid plastics, eliminating the need for additional fixings in many applications and helping to speed up installation.

Its advanced acrylate adhesive offers excellent water resistance, making it suitable for exposed conditions while ensuring dependable long-term adhesion.

At the same time, its exceptionally low VOC rating helps support healthier indoor air quality for installers and building occupants alike.

Whether sealing membrane overlaps or connecting vapour control layers to structural elements, Pro Clima Duplex offers a dependable, cost-effective solution for achieving airtightness and weather protection.
