The important factors affecting the sound insulation effect of bridge broken aluminum doors and windows.

The important components of a complete set of broken bridge aluminum doors and windows are window frame, hardware and glass. The quality of these parts will affect the sound insulation effect of windows.

Let's talk about glass first

The thicker the glass is, the better the sound insulation effect will be. Generally, for windows, we will configure 5cm thick glass. This thickness of glass meets the national standard. The sound insulation effect is very good. Glass with a thickness of 3 cm or 4 cm is not suitable for windows The thicker the glass is, the slower the propagation speed will be, and the more attenuation the volume will be. Therefore, the thicker the glass is, the better the sound insulation effect will be. Glass with a thickness of 3 to 4 cm is easy to be damaged in bad weather due to its insufficient strength and poor wind pressure and impact resistance

 Important factors affecting sound insulation effect of bridge broken aluminum doors and windows

Broken bridge aluminum doors and windows will generally be installed with insulating glass, two or three pieces of glass when the sealing will also affect the sound insulation of the window, ordinary small brands will ignore this part, such as our regular manufacturers will use the glass made by large-scale glass factory, because they will be very strict with the sealing standard of glass lamination The material and technology can meet the national standard

Different types of window profiles will also affect the sound insulation of windows. The size of 6070 profile is different, and the size of insulating glass is also different, so its sound insulation effect is not the same. 70 profile is a 23 mm hollow layer, 60 profile is 15 mm hollow layer, the wider the hollow layer, the slower the sound transmission speed, and its sound insulation will be better. For example, the sound near the sound source will be greater, and the farther away the sound will be smaller.

Whether the hardware assembly is appropriate and the quality of hardware will also affect the sound insulation of bridge broken aluminum doors and windows. If the aluminum doors and windows are not closed tightly, there will be gaps, which will affect the sound insulation effect of the doors and windows. The main problem is that the sash is not closed tightly. The high-quality hinge has a very strong load-bearing capacity, which can ensure the close connection between the window sash and the window frame, so that the closing of the window sash is tight. And the poor quality hinge is likely to be unable to bear the weight of profiles and glass due to its own bearing capacity defects, resulting in the phenomenon of subsidence and deformation of the window, so that the window is not tightly closed, and the sound insulation effect will certainly be affected. Regular manufacturers use high-quality hardware of high quality, each performance has reached the national standard, can ensure the normal opening and closing of windows, so as to ensure the sound insulation effect of windows.
