I believe that many people are familiar with broken bridge aluminum windows, but many consumers only care about the price when purchasing broken bridge aluminum doors and windows, ignoring a lot of configuration things, especially glass selection, many consumers think that window choice Big brand aluminum, imported hardware is no problem, and glass selection is often considered to be of little significance. It is believed that there is no difference between glass and glass, and they are all transparent. In fact, the selection of glass is very important. To a certain extent, it determines whether the windows of your home are thermally insulated and sound-insulated.
1. Why use tempered glass for broken bridge aluminum windows?
We know that the standard window glass of merchants is generally ordinary insulating glass. Many people think that this kind of glass is enough and there is no need to upgrade it to tempered glass. Many northern consumers have plastic steel doors and windows in their homes, and most of them are ordinary glass. Consumers have never seen their own glass self-crack, and think that general glass is fine, so why must the broken bridge aluminum windows be upgraded with tempered glass?
Because the window used to be a plastic-steel window, the material is plastic, and there is a buffer strip between the frame and the glass, whether it is thermal expansion or contraction of the window or glass, there is little self-cracking phenomenon, while the broken bridge aluminum window is different, the material It is a metal aluminum alloy material. The glass is in direct hard contact with the metal, and at the same time, the elastic tension of the glass glue will cause the glass to self-crack without external force. Although this is not the case for every glass, the broken bridge aluminum The probability of self-cracking of glass is much greater than that of tempered glass.
In terms of cost performance, consumers are also advised to choose tempered glass. Taking Beijing as an example, now the door and window installers are paid 400 to 500 yuan a day, and Beijing has traffic jams. Generally, two users will run to replace the glass a day. If a piece of self-breaking glass is replaced, In addition to labor, materials, and shipping costs, the glass with a small area does not have four or five hundred yuan, and the merchant will not replace it. If the tempered glass is upgraded in the window selection, the 10-square-meter tempered glass window will only cost 600 yuan more than ordinary glass. , If you replace the 10 square meters of glass, it is not the price, so it is recommended to choose tempered glass for long-term consideration. In the south, the windows of the balcony are basically tempered glass, and there are few ordinary glass.
From the point of view of safety, tempered glass has higher strength and better safety than ordinary glass, especially if the windows in the home are floor-to-ceiling windows, and if the glass is large glass, tempered glass must be selected, and it is especially suitable for children and elderly people at home. Tempered glass is selected, and the tempered glass bursts into small particles, which does not hurt people.
2. What is the relationship between broken bridge aluminum window glass and sound insulation and thermal insulation?
We know that a door and window, 30% of the area is the material frame, and 70% of the area is glass area, so a large part of the window’s thermal insulation and sound insulation is determined by glass. Conventional broken bridge aluminum windows First of all, tempered glass should be selected. Secondly, the owner with the conditions can choose double-layer insulating glass with Low-E function, or even three-layer insulating glass with Low-E. This kind of glass configuration can greatly improve the sound insulation, heat insulation and thermal insulation effect of windows. , the price is also a little more expensive than ordinary transparent glass, but in the long run, it is still worth the money.
According to some data, Low-E glass can save 60%-70% of energy in one year compared with ordinary glass. The same west-facing house, if it uses ordinary glass, can use 135 kWh of electricity a year, but if it uses Low-E energy-saving glass, it only needs 54 kWh of electricity a year, which is 81 kWh less per year. Since energy-saving glass can save so much electricity, why is it not popular in residential buildings? Because Low-E glass is more expensive than ordinary glass, our consumers often only look at the discounts in front of them, and do not count the benefits that can be brought about after use.
