Generally speaking, the sound insulation and thermal insulation of the steel structure are mainly made of glass fiber wool. The steel structure plant has good thermal insulation effect. The insulation board used for the external wall can effectively avoid the "cold bridge" phenomenon of the wall and achieve better insulation effect.
The thermal resistance of R15 insulation cotton with a thickness of about 100 mm can be equivalent to the brick wall with a thickness of 0.5 m. Sound insulation effect is a very important indicator for residential buildings. No one wants to be noisy every day. The windows installed by the steel structure light steel system are all hollow glass with good sound insulation effect?, Sound insulation is more than 40 db; The sound insulation effect of the wall composed of light steel keel and thermal insulation material gypsum board can be as high as 60 dB. Therefore, the steel structure has many advantages, such as short cycle, low cost, environmental protection, and reusable materials.
