Earthwool OmniFit Acoustic Partition Insulation slabs and rolls

Earthwool OmniFit Acoustic Partition Insulation slabs and rolls

The Earthwool OmniFit Acoustic Partition Insulation slabs and rolls range is a new generation of softer and more environmentally friendly insulation. Specially designed slab for friction fit in between metal or wooden frame studs for efficient and effective installation.

Earthwool is naturally brown – containing no added phenols, formaldehyde, acrylics or artificial colours. Advanced compression packaging reduces handling time and the risk of damage in transit and on-site.

This specialist acoustic range of insulation products is available in 50mm standard sound absorbing performance and 75mm ultra sound absorbing performance levels. Earthwool OmniFit Acoustic Partition Insulation slabs and rolls reduce unwanted noise from outside and also limit sound transmission from room to room or office to office.
