Megasorber N

Acoustic Underlay


isolation underlay

Megasorber N8 is a vibration isolation material. The product is designed to provide excellent impact sound insulation as well as excellent isolation, resulting in an increase in the sound transmission loss.

Megasorber N8 can be glued between the subfloor and under the floor finish to form a floating floor system. The soft and resilient properties, combined with a high internal loss, makes it one of the most suitable materials on the market to reduce foot stepping noise. It can also be used as an underlay for carpets or synthetic grass to improve underfoot comfort.

Megasorber N8 is 100% recyclable.
