Adhesive tapes & sealants

Tapes and sealants for airtightness and sealing

Tapes and sealants are essential components of modern airtightness and sealing systems. They ensure secure bonding of membranes, films, joints, and penetrations, helping to prevent heat loss, drafts, and moisture damage over the long term.

In our range, you will find tapes and sealants for various applications in roofs, walls, and building envelopes. Whether for vapor control layers, roof underlays, façade membranes, or connection details – we offer suitable products for new construction, renovation, and timber construction.
