G20J metal damping soundproofing board is a high-performance soundproofing solution. The front and rear surfaces are made of inorganic materials with different densities and thicknesses, and the core layer is made of soft aluminum plate. The high-density board on the front and the soft aluminum plate in the core layer have efficient transmission of shear stress, performing well and effectively isolating mid to high frequency and ultra-high frequency sounds.

The dimensions are 1220mm (length) x 1220mm (width) x 18mm (thickness), with each piece occupying 1.4884m²and weighing 39.75kg. It is made of inorganic and metal flame-retardant environmentally friendly materials, providing direct full frequency and high sound pressure insulation. It is worth noting that its noise reduction index for airborne and structural propagation is three times that of similar soundproof panels.

G20J board is suitable for bars, nightclubs, high noise computer rooms, active sound insulation structures, and high sound pressure level soundproof doors with high pressure levels. It is a powerful choice for dealing with strong noise in harsh environments. Whether you need to quiet down a bustling nightclub or a noisy computer room, this board can provide excellent sound insulation performance.
