DAMTEC Multi

The DAMTEC® Multi membrane is a pressed rubber granulate, bonded with a polyurethane elastomeric bonding agent.

DAMTEC® Multi is suitable for use on floors, walls and ceilings.
It is effective both under the cement screed and above it, directly under hard or soft floor coverings, such as natural parquet, laminate, tiles, carpets and others.

Thanks to its excellent thermal conductivity, DAMTEC® Multi is ideal for use with underfloor heating systems.
Also effective when installed in combination with plasterboard panels, preventing airborne noise.
It perfectly replaces XPS or stone wool boards between double walls, gaining space and again stopping the passage of airborne noise.

It provides excellent sound insulation at a minimum thickness, making it suitable for projects with limited spaces or floor heights.
