SoundMat 3 Plus is an extremely efficient sound absorber and can greatly increase the acoustic performance of timber floors, ideal for reducing impact/vibration noise and medium levels of airborne noise (such as talking and TV noise).

SoundMat 3 Plus is our best selling direct to timber floor soundproofing system.

The unique three layer construction of the SoundMat 3 Plus is made up of a 9mm high impact closed cell acoustic foam, which absorbs vibrations before it can transfer through to the timber floor. This is laminated to a 3mm and 3mm SoundBarrier Mat (7.5kg mass loaded vinyl) which has the same mass and density as lead and is exceptionally efficient at blocking airborne noise. The result is the most cost effective thin soundproofing mat on the market.

Please note, using this on the walls behind an acoustic plasterboard will give you no acoustic benefit.
