Grei Range

Sound Insulation for Floating Screeds

Grei range sound insulation from Whisper AcousticsThe Grei range comprises products for the sound insulation of floors. It was developed to be used in the construction of buildings and has a high quality performance capacity. Use of the special EPDM rubber and a particular patented design give this line of products important mechanical and acoustic characteristics, which are ideal for impact noise insulation for all kinds of floors. The resistant and flexible mat adapts perfectly to the surface base and, thanks to its self-adhesive border seam, it is extremely easy and quick to lay with precision.

The Grei  range is part of our family of rubber products, created with eco-compatible technologies and production processes that allow for more than 92% of recycled and/or regenerated materials to be used. This line contributes to achieve the LEED® point rate system into the code area of MR 1-1.1 - 1.2-2-3- 4- 5.
