The sound insulation performance of the prefabricated house is better

1. The wall of the prefabricated house:

The sound insulation performance of the prefabricated house is better. The thickness of the wall is about 18 centimeters (the thickness can be adjusted according to the environment), of which 3 centimeters are extruded panels and 10 centimeters of glass fiber cotton. Double insulation layer of glass fiber wool and extruded plastic board.

2. Gypsum board:

The prefab house is a kind of material made of building gypsum as the main raw material. It is a kind of building material with light weight, high strength, thin thickness, convenient processing, sound insulation, heat insulation and fire resistance.

Gypsum board has been widely used in interior partition walls, wall cladding panels (instead of wall plastering layers), ceilings, sound-absorbing It is not suitable to be installed in the bathroom or kitchen for indoor use.

3. Glass wool:

Glass wool is made of centrifugal glass wool felt which is unique to Owens Corning (OC for short) Patented centrifugation technology, a product made of molten glass fiber and an environmentally friendly formula binder based on thermosetting resin. It is an elastic felt-like body made of glass fibers with a diameter of only a few microns. . It has a large number of tiny air pores, which make it play the role of thermal insulation, sound absorption and noise reduction, and safety protection. It is the best material for thermal insulation, sound absorption and noise reduction of steel structure buildings. The fibers are fluffy and staggered, and there are a large number of tiny pores. It is a typical porous sound-absorbing material with good sound-absorbing properties.

In large spaces such as gymnasiums and workshops, in order to absorb sound and reduce noise, sound absorbing bodies with centrifugal glass wool as the main sound absorbing material are often used. In road sound insulation barriers, in order to prevent noise reflection, it is necessary to take sound absorption measures on the side facing the vehicle. Centrifugal glass wool is often used as a filling material, and the surface layer is a barrier board with perforated metal plate.

Activity The sound insulation of the outer wall of the prefab house is greater than 55 decibels, and the indoor partition walls can be constructed in different ways according to the needs. The maximum sound insulation can reach 66 decibels, far exceeding the national sound insulation standard of five-star hotels.

The material of the prefab house is better and more popular with the public. The sound insulation of the outer wall of the prefab house is greater than 55 decibels. The indoor partition walls can adopt different structures according to the needs. The maximum sound insulation can reach 66 decibels, which is far more than National five-star hotel sound insulation standard.
