Phonestar DB Boards
The DB Board is a high-density sand filled board which can help to reduce Airborne noise through walls. These boards are 15mm thick and have a corrugated sand filled carcass. The DB board has both soundproofing and thermal properties (on timber or steel framed structures).
Mass Loaded Vinyl (MLV50)
This a 2.5mm thick rubber sheet adding 5kg per square meter. The membrane is made from recycled materials and works as an excellent barrier to airborne noise.
Green Glue
Green Glue is layered between the two layers of board. The science behind green glue is that when soundwaves hit the glue, it disperses these vibrations into smaller vibrations within the boards. These then shear along the two sides of the boards, causing friction and the glue to changes these vibrations into heat. The heat dissipates, which reduces the vibration. This conversion of energy from sound vibration to heat is called damping and this is what lays at the core of this product
