Although there is no specific national and standard. In fact, the word "energy-saving doors and windows" has been mentioned in the industry, but the small editor of golden school Huating doors and windows thinks that these views are somewhat one-sided.

It is generally believed that energy-saving aluminum alloy doors and windows are actually coated glass, Low-E glass, etc. as long as the use of this form of glass can be called energy-saving doors and windows. I don't quite agree with that. When it comes to doors and windows, in fact, it is a huge industrial chain, and it is also the integration of many marginal disciplines. Such as rubber industry, such as wood processing industry, non-metallic surface treatment and many other disciplines. Any small detail will affect the overall performance of doors and windows. For example, if the common adhesive strips on the market are used, the adhesive strips may be aged and deformed in less than one year, resulting in air leakage and poor sealing effect. How to save energy? Energy saving doors and windows should be considered from the following aspects:

 Energy saving of aluminum alloy doors and windows depends on the technology of doors and windows

1. Material of doors and windows

Now the materials of doors and windows are aluminum alloy, plastic steel, plastic, solid wood, and maybe some iron. There is a common sense that we all know that iron and aluminum have very high thermal conductivity, a little heat will be emitted, so it is always cold in winter. In recent years, plastic steel windows and plastic windows are popular, but the strength of the windows made of this material is not strong enough, and it is easy to become brittle, so the safety can be imagined. At present, wood window is energy-saving and environmental protection, but it has its own defects, it is not easy to burn, easy to rot, easy to crack and so on. But after special process and technical treatment, the wood is very stable. But at the same time, the price of wooden windows is not cheap.

2. Glass

Glass occupies most of the area of doors and windows, so it plays a very important role in energy saving. There are several types of glass on the market: first, ordinary glass, which has not been tempered; second, ordinary tempered glass; third, coated glass; fourth, Low-E glass. Each type of glass can also be subdivided. So which kind of glass has good energy-saving effect? It should be Low-E glass, which can filter out harmful light such as infrared ray, far-infrared ray and ultraviolet ray, with remarkable energy-saving effect. In recent years, the state requires high-rise buildings to use insulating glass, that is, two-layer glass. But look at the market side of the insulating glass are specious, may be just a simple two layers together, the real insulation effect did not achieve. In Germany, their buildings already require three layers of glass. To tell you the truth, it is the same hollow glass, China's hollow and Germany's hollow is very different.

3. Energy saving of doors and windows is the whole energy saving

When it comes to energy-saving of doors and windows, it is actually the energy-saving of the whole window. Relying on glass alone can not achieve the purpose of energy-saving. The sealing performance of doors and windows is also an important parameter affecting energy saving. If there is a problem with the sealing of doors and windows, the energy will also be easily lost. The sealing of doors and windows includes the following aspects: firstly, the selection of sealing materials. Good sealant strip is flexible and elastic, and has strong weather resistance. Even if it is 20 ° below zero, it can also maintain its toughness. In addition to the sound of wolf howl, the door and window need to be treated by special technology.

In a word, the energy saving of doors and windows depends not only on the material, but also on the glass and the technology of the doors and windows.

Aluminum alloy doors and windows to choose hollow glass built-in shutter doors and windows popular is a reason!   [ Back to home page ] [ Printing ] [ Back to previous page ]    Look, listen and touch three ways to overhaul aluminum alloy doors and windows
