Product information

Recycled rubber for sound absorption in sand/cement floors

Damtec Estra Sample 2Damtec® Estra is the ideal insulating and vibration-separating padding underneath floating screed floors and also provides significant reduction of footfall sound within the room. Unlike other systems, floating floors reduce sound transmission and impact sound by the design of the sub floor itself. Damtec® Estra is ideal in floating screed systems, providing extremely high resistance to compressive loads and outstanding elasticity. It is equally well suited for applications in residential, office and commercial buildings. Damtec® Estra is particularly quick and easy to install, can be loose laid and provides a wide range of benefits in screed floor construction including long service life and superb strength.

Outstanding properties for outstanding floors

Damtec Estra Under Screed FlooringDamtec® Estra has everything you need for long life and reliability in insulating and isolating vibration for floating screed floors. Its excellent resiliency and static bearing performance are complemented by its superior long-term compressive stability. In addition, Damtec® Estra has outstanding resistance to rot degradation. Damtec® Estra, like the rubber granulates used to make it, is 100% recyclable.
