The energy saving of curtain wall accessories and doors depends on the process of doors and windows

[China Aluminum Network] Although the country has not yet introduced specific standards and indicators. In fact, the term “energy-saving doors and windows” has already been mentioned in the industry, but Xiaobian thinks these views are a bit one-sided.

The general view is that energy-saving doors and windows are actually coated glass, low-e glass, etc. As long as this form of glass can be used as energy-saving doors and windows. I do not agree with this point of view. When it comes to doors and windows, it is actually a huge industrial chain. It is also a synthesis of many frontier 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 the doors and windows. Such as plastic strips, if you use the ordinary plastic strip on the market, may be less than a year plastic strip will be aging, deformation, leading to air leakage, sealing effect is very poor, but also talk about energy-saving it? Energy-saving doors and windows should be considered from the following aspects :

First, the door and window material

The doors and windows are made of aluminum alloy, plastic steel, plastic, solid wood, and may have some iron. There is a common sense estimate that we all know that iron and aluminum have very high thermal conductivity, and that a little heat will be emitted, so the house is always cold in winter. In the past few years, plastic windows and plastic windows have become popular, but the window strength of this material is not large enough, and it is easy to become brittle. The security can be imagined. At present, wood windows are energy-saving and environmentally friendly, but wood windows have their own defects and are not easy to burn, perish, and crack. However, the wood is very stable after special processing and technical treatment. But at the same time, the price of wooden windows is not cheap.

Second, glass

Glass occupies most of the area of ​​doors and windows, and therefore plays a very important role in energy saving indicators. There are several types of glass on the market: First, ordinary glass, not tempered; Second, ordinary tempered glass; Third, coated glass; Fourth, low-e glass. Each glass can also be further subdivided. So what kind of glass energy-saving effect is good? It should be low-e glass, it can filter out infrared rays, far infrared rays, ultraviolet rays and other harmful rays, energy-saving effect is remarkable. In recent years, the state has demanded that high-rise buildings use insulating glass, which is two layers of glass. However, if you look at the insulating glass on the market side, it's just a plausible one. It might just be a simple two-layer fight. The real insulation effect has not been achieved. In Germany, their buildings already require triple glazing. To tell the truth, it is the same kind of hollow glass. The hollow of China and the hollow of Germany are far from one another.

Third, the energy saving of doors and windows is the overall energy-saving

When it comes to the energy saving of doors and windows, it is actually the energy saving of the whole window, and relying solely on glass cannot achieve the goal 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 the doors and windows, energy can also be easily lost. Sealing of doors and windows includes the following aspects. The first is the choice of sealing material. The good sealing tape is flexible and flexible, and has strong weather resistance. Even at minus 20 degrees, it can maintain its toughness. In addition to the sealant strips, doors and windows need to undergo special processing to balance the pressure difference between the room and the outside.

All in all, the energy saving of doors and windows depends not only on the material, but also on the glass, but also on the process of the doors and windows.
