On the whole, the sound insulation effect of broken bridge aluminum doors and windows is better than that of plastic steel, but as long as the equipment will have the function of sound transmission, so the general sound insulation doors and windows of the equipment are as narrow as possible to reduce the area of sound transmission, the general sound insulation of broken bridge aluminum doors and windows mainly relies on glass to play most of the role. In addition to sound insulation, plastic steel is essentially plastic material, and it is certainly not as durable as broken bridge aluminum doors and windows, and it is relatively easy to age.
Soundproof glass
The reason why the glass is soundproof, mainly the area of glass is large, the area that can transmit sound is also larger, generally when choosing the door and window brand, we need to see clearly which brand the supply glass dealer of this brand is, if it is a supplier of small brands, the quality of the glass is difficult to guarantee.
Most of them use Table Glass and Xinyi Glass, these two brands are giants in the glass industry, there is a strong guarantee of quality, and we will also carry out crushing experiments after procurement, which double guarantees the quality of glass.
For example, double-layer, three-layer insulating glass and laminated glass are common now.
Insulating glass
This glass type is a combination of multiple pieces of glass, which is dry air in the middle, which has a good sound insulation effect for the sound of the street and the sound of the whistle.
Laminated glass
This glass sandwich thing is polyvinyl butyral as the main component of the pvb interlayer, ordinary laminated glass has a sound insulation volume of 28-34 decibels, professional sound insulation glass sandwich thing is a sound insulation film (sound insulation damping adhesive), its sound insulation volume can reach 35-40 decibels. Laminated glass has a pretty good effect on low- and medium-frequency noise on the road.
