Under screed/ underfloor resilient layer acoustic insulation.
Resilient Layer Insulation, suitable for floors with floating screeds, floors with floor joists, and for use as vibration insulation of plant rooms.
To install:
Resilient Layer 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).
