G20J Sound Insulation Board
The G20J metal damping and sound insulation board is a composite board: the front and rear surfaces are made of inorganic materials with different densities and different thicknesses with soft aluminum sheets arranged in the core layer, and two layers of high polymer damping material molded compositely under high pressure around it. This multi-density structure results in a product with excellent sound reduction against airborne & structural noise making it ideal for building soundproof partitions. The board is designed to replace the regular use of gypsum board in building construction. As such, it is highly effective in increasing the sound reduction of wall, ceiling and floor partitions greatly.
