Upgrei is an innovative impact sound insulation underlay for use as an under screed resilient layer on floors. Developed with cutting-edge technology, it is a high-performing acoustic mat used in the construction of very thick, high specification floors.
An extension of the Grei Acoustic Underlay, it is made from specially selected EPDM rubber granules which are bonded to 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.
Upgrei is ideal for the impact noise and thermal insulation of any type of floor, especially where there is a need for high acoustic performance. A waterproof version – Upgrei PTB is also available. Impact sound reduction values of up to 32dB is possible using the Upgrei sound insulation mats. 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.
