Phonestar DB Boards
DB Board is a high-density sand filled board which can help to improve sound insulation and acoustic insulation, reducing both airborne and impact noise. These boards are 15mm thick and have a corrugated sand filled material. The DB board can be used on floors, walls and ceilings and has both soundproofing and thermal properties (on timber or steel framed structures).
Mass Loaded Vinyl (MLV50)
MLV50, or Mass Loaded Vinyl, is a 2.5mm thick rubber sheet that adds 5kg per square meter and aids the Resilient Bar Ceiling System with additional sound insulation. The specially designed membrane is made from recycled materials and works as an excellent acoustic insulation barrier to airborne noise.
Green Glue is a soundproofing-specific material that is layered between the two layers of sound insulation board. The science behind green glue is that when soundwaves hit the glue, it disperses these vibrations into smaller vibrations within the boards, further enriching the acoustic performance of the Resilient Bar Ceiling System. These then shear along the two sides of the boards, causing friction that the special glue changes help convert the vibrations into heat. The heat dissipates, which reduces the vibration, thus helping to create an acoustic plasterboard. This conversion of energy from sound vibration to heat is called damping, which is one of the special elements that aid soundproofing and soundproofing, making it the core of this product.
