insulSound Ultra+

Reduces the parquet floorings’ resonance 20 dB

Our acoustic underlay designed to reduce the sound of floating parquet floorings or laminates

InsulSound Ultra+ is a new and revolutionary high-performance acoustic underlay for laminates or semi-solid floating parquet floorings.

insulSound Ultra+ is made of a 2 mm thick physically crosslinked polyolefin foam with closed micro cells covered with an untearable and waterproof HDPE film.

InsulSound Ultra+ very effectively reduces impact noise between floors, but it also reduces the reflected walking sound in the room where the sound is emitted.

InsulSound Ultra+ is very easy to install thanks to its smooth, tear-proof HDPE film on the top of the product. A perfectly flat and self-adhesive covering system ensures that the joints are held together tightly and securely. Being waterproof, the insulSound Ultra+ acoustic underlay also provides a good moisture protection for your parquet.
