Centrifugal glass wool felt goods are made for large laying area. Besides the character of thermal preservation, it also has the performances of vibration absorption and noise absorption, especially for middle or low frequency sound, which can cancel the noise and improve working environment.
This material can be freely cut in construction according the shape required, mainly used in room, noise-canceling system, transportation, refrigerators and household electric appliances for noise canceling. The effect is pretty excellent.
The glass wool felt goods with aluminum foil surface has good capability of heat radiation protection, which is suitable for high temperature workshops, control room, inner wall of the machine rooms, room separating and so on as inner liners.
