Soundproofing has been made easy with PhoneStar, 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, television noise) and impact sound reduction (e.g. footstep and furniture dragging noise)

through soundproofing floors, walls and ceilings, in one single product. It is also CE marked. Because it is only 15mm thick, PhoneStar 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. In addition, it adds thermal mass to the structure so is very beneficial to use on timber frame or lightweight buildings which tend to overheat in summer. The PhoneStar board will absorb the heat during the day and release it at night-time as the room cools.
