PhoneStar SBX Sound Insulation Board
Soundproofing has been made easy with PhoneStar, SBX board which is a very versatile, high-performance and simple-to-use acoustic insulation product that exceeds Building Regulations for the Resistance to the Passage of Sound in the UK and Ireland. This eco-friendly, natural and breathable soundproofing board provides outstanding results for both airborne sound reduction (e.g. talking, music, and television noise) and impact sound reduction (e.g. footstep and furniture dragging noise).
Soundproof floors, walls, and ceilings with one single product. It is also CE marked. Because it is only 15mm thick, PhoneStar SBX board is an ideal soundproofing solution for new builds, conversions, refurbishments and remedial projects, because it takes up very little precious room space and is easy to install.
