Liquid airtight sealant

Liquid airtightness solutions for secure connections and detail areas

Liquid airtightness products are used wherever connections, transitions, and complex detail areas need to be sealed in a permanently airtight manner. They are particularly suitable for areas where tapes or grommets can only be used to a limited extent, offering a flexible and secure application on various building components.

In our range, you will find liquid airtightness products for sealing connections, penetrations, and transitions in roofs, walls, and building envelopes. They support a permanently effective airtight layer in new construction, renovation, and timber construction.

Liquid airtightness for roofs, walls, and building envelopes

Especially in complex connection areas, reliable and durable sealing is essential. Liquid airtightness adapts to irregular substrates and enables secure application even in hard-to-reach or geometrically challenging areas. This helps effectively prevent heat loss, drafts, and moisture damage.

As a specialist supplier for insulation and sealing systems, we offer liquid airtightness products for professional applications in airtightness and connection details. We are happy to assist you in selecting the right solution for your construction project.
