UPGREI - for floating floors

Designed for impact and thermal insulation of all types of floor slabs, especially when high acoustic performances are required.

Upgrei is made using a special type of EPDM rubber that exploits the tried and tested Grei technology, coupled with a resistant polyester fibre layer.

The extremely resistant yet flexible mat adapts perfectly to the underlying surface and - thanks to the self-adhesive joining edge - allows for joining the edges of the rolls without having to use adhesive tape. As a result, the product can be applied easily and precisely, in a much shorter time.


  • Very high acoustic and thermal performance
  • Extremely easy to lay
  • Resistant to dampness
