FANRYN centrifugal glass wool blanket are made for large laying area. Beside the character of thermal insulation, it also has the performances of shock absorption and acoustical isolation, 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-cancleling system,transportation,refrigerators and household electric appliances for noise canceling.
