In constructing sound – proofing facilities in a building, sound – absorbing and insulating materials should be applied to the wall. Room noise is then remarkably reduced, and the noise to leak out is minimised, thus almost completely preventing neighbouring buildings from receiving noise pollution. Sound-proofing is possible without revising the existing frames, while a good appearance is ensured as well as superior heat insulation; the sound-absorbing material is non-flammable owing to inorganic property.
Being used for treating the source of noise, sound proofing box reduces the sound transmission. By reducing the noise in the interior side of the box as well as noise from exterior side, the product improves working environment. With a smart structure, it uses sound-absorbing, sound-insulating materials having good effects of water-proof, heat-insulating and moisture-proof.
