Marine Glass Fiber Products Series
A) Marine Glass Fiber Plate
- Glass wool products are an ideal sound-absorbing materials and compared to other thermal insulation materials, sound-absorbing effect of which are the best, following the sound absorption coefficient by reverberation room method is, sound absorption coefficient is at frequencies of 250, 500, 1000.
