Phonestar Boards

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.

Phonestar Sound Insulation Performance

The PhoneStar soundproofing board on its own has been certified to reduce Airborne Sound by a very high 36 Decibels (dB) (Rw, Ctr = -4). When the acoustic insulation board is then added to a wall, floor or ceiling structure, the overall Airborne Sound Insulation result of the complete structure will be much higher. Please note that when comparing Airborne Sound Insulation results of a complete wall, floor or ceiling structure, the higher the result the better the reduction in airborne sound.

PhoneStar reduces Impact Sound by a very significant 21dB (ΔLw) when laid on the industry standard concrete test floor. The overall impact sound insulation result of the complete floor and ceiling structure can also be tested and this laboratory result in Decibels is denoted by Ln,w. Please note that when comparing Impact Sound Insulation results of the complete floor structure, the lower the result the better the reduction in impact sound.

The Phonestar Soundproofing Carcass

PhoneStar is a dense product with a high mass, but it is also soft due to its compacted but loose quartz sand filling contained within an engineered, fluted cardboard carcass. These are the critical characteristics required for noise reduction and it also has unique self-decoupling properties.
