Product description

The UpGrei  line consists of a range of innovative products for sound and thermal insulation of floors. Developed with cutting-edge technology, they are high-performing products used in the construction of very thick floors. The products, which capitalize on Grei's tested technology, are made with special EPDM rubber granules and a layer of polyester  fibre.
The combination of these two materials results in a product that has very high acoustic, thermal and mechanical performance capacity.
The UpGrei  line is ideal for impact noise and thermal insulation of any type of floors, especially where there is a need for high acoustic performance. It also provides a barrier to vapour when the waterproof anti-tear support is used on the products.
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 UpGrei  line 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.
