Acoustic insulation designed to reduce sound transmission between floors. It's specifically made for use under high-quality concrete slabs, and blocks a high level of noise.

Available in two versions: Grei (7 mm - for traditional floors) and Upgrei (10 mm - for heavy duty floors).

Features and benefits:

Noise reduction: A unique combination of ethylene propylene diene monomer (EPDM) rubber and a patented process creates a mat that's both strong and flexible. The material absorbs impact sounds, making floors quieter.
Easy to install: The mat is designed to fit on any surface. Edges have a built-in adhesive overlap, so no extra tape is required to connect the rolls. This makes installation quick and simple.
Suitable for use with underfloor heating.
VOC-free.
Manufactured from recycled materials.
Impact sound reduction of up to 26 dB (Upgrei) or 24 dB (Grei).
