PhoneStar

6 DSC 0860

A new era of soundproofing

PhoneStar is a revolutionary soundproofing board, made of a combination of sand and cardboard. Designed to reduce both impact and airborne sound, while adding thermal mass to structures.

The decoupling fleece acts as a decoupling layer between PhoneStar boards and the structural floor, separating the two hard surfaces.
