Ideal for timber floors, the PhonoMat 7 SlimLine is a superior product that outshines all acoustic underlayment systems currently on the market. This is due to its double mass loaded vinyls and the use of the cross linked foam impact layer, granting the product longevity, lasting years of ‘bounce back’ properties, when comparing to lower grade foams.
As traditional non cross linked foams which you can expect only 1-3 years service, and if there is a continuous point load on the lesser grade foam then it will lose its shape reducing acoustic performance.
