Generally depends on the environment used, glass wool and extruded board are completely two different materials.
The sound absorption effect of glass wool is better, but also has the performance of fire prevention and heat insulation, belongs to the class A non-combustible material. The sound insulation effect of the extruded board is poor. If the temperature difference between the two sides is too far, it is easy to appear dew. If it is a partition or the indoor temperature difference is not large, the extruded board is still ok.
Uetersen glass wool board is the use of centrifugal technology, will melt glass fibrosis, by adding thermosetting resin based environmental protection formula binder curing processed from the plate products. The slender glass fiber has low thermal conductivity, which can well confine air, thus playing the role of heat preservation and insulation, sound absorption and noise reduction and safety protection.
1. Roof insulation, cooling and sound-absorbing materials;
2, building insulation, cold;
3, entertainment venues, theaters, TELEVISION stations, radio stations, laboratories, sound-absorbing processing;
4, air conditioning pipe refrigeration and refrigerated warehouse insulation.
