The glass configuration of the current aluminum doors and windows of the broken bridges is mostly double-layer hollow tempered glass, and the sound insulation effect has been excellent. However, now that there are three layers of insulating glass, is the three-layer insulating glass more necessary or more redundant than the double-layer insulating glass?

At present, the aluminum door and window structure of the broken bridge is basically made of 5+9+5 or 5+12+5 hollow glass, which is an air gap of 9mm or 12mm between the two layers of 5mm glass, because of the conductivity of glass and air. Different, so as to maintain the effect of insulation and sound insulation. Almost all of the broken glass is made of broken aluminum.

When three layers of insulating glass are formed, such as 5+6A+5+6A+5, the thickness of the middle air layer is reduced, and a layer of glass is added. It is reasonable to say that the sound insulation of glass is mainly based on the thickness of the air layer of the insulating glass. The greater the thickness of the air layer, the better the sound insulation effect. Like the current broken aluminum 70 series, it can reach the glass configuration of 5+22A+5. The effect is weak and weak and requires precise experimental measurements.

Therefore, it is only one-sided because the sound insulation effect is good only according to the number of glass layers. The effect of the aluminum door and window of the broken bridge is not limited to several layers of glass, but has a great correlation with the thickness of the gap between the glass.

Three layers of insulating glass and double-layer insulating glass each have its own merits

In addition, the sealing performance of the doors and windows has a great influence on the sound insulation. If the three-layer glass is used to seal the sash, the handling is not serious, and improper handling will seriously affect the performance.

Of course, the three glass is white, the double-layer hollow, the sound insulation effect is much better than the ordinary hollow effect. Generally used in the three northeastern provinces or alpine regions, the sound insulation effect is much better than the ordinary hollow effect. Therefore, the three-layer insulating glass and the double-layer insulating glass have their own advantages. When installing the broken aluminum doors and windows, it is necessary to make a choice according to the actual situation of each region according to their own budget.
