Energy Saving Aluminum Doors and Windows

With the rapid development of the doors and windows, now energy-saving doors and windows are getting more and more attention. And, do you know what is energy-saving doors and windows?


First, what is energy-saving doors and windows?


The general public view is that energy-saving windows and doors are actually coated glass, low-e glass, etc., as long as this form of glass can be called energy-saving doors and windows. Actually not! When it comes to doors and windows, it is actually a huge industrial chain. It is also a combination of many marginal disciplines, such as the rubber industry, such as the wood processing industry, non-metal surface treatment and many other disciplines. Any small detail will affect the overall performance of the doors and windows, such as plastic strips. If the ordinary strips on the market are used, it may take less than a year for the strips to age, deform, cause air leakage, and the sealing effect is very poor. What?


Second, the three major elements of door and window energy saving.


1, door and window material


Now the doors and windows are made of aluminum alloy, plastic steel, plastic, solid wood and broken bridge aluminum. There is a common sense that everyone knows that iron and aluminum have very high thermal conductivity, and a little heat will be emitted, so the winter house is always cold. Plastic steel windows and plastic windows have been popular in the past few years, but the strength of this kind of window is not big enough, it is easy to become brittle, and the safety can be imagined. The wooden window has excellent energy-saving and environmental protection performance, but the wooden window has its own defects, and it is easy to burn, easy to rot, easy to crack, etc., and the price of wooden windows is not cheap. At present, aluminum alloy doors and windows have the best energy-saving and environmental protection performance. It not only solves the shortcomings of high thermal conductivity of aluminum alloy, but also compensates for the low strength of plastic steel and plastic, and the price is relatively low compared with solid wood.


2, glass


Glass occupies most of the area of doors and windows, so it plays a very important role in energy-saving indicators. There are several types of glass on the market: one is ordinary glass, which has not been tempered; the other is ordinary tempered glass; the third is coated glass; the fourth is low-e glass. Each glass can also be subdivided. So which kind of glass has the best energy saving effect? It should be low-e glass, which can filter out harmful light such as infrared rays, far infrared rays and ultraviolet rays, and the energy saving effect is remarkable. In recent years, the state has demanded that high-rise buildings use insulating glass, which is two-layer glass. But look at the hollow glass on the market side is plausible, it may be just a simple two layers together, the real insulation effect is not achieved.


3, door and window 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. It is impossible to achieve energy saving by relying solely on glass. 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, the energy will also be lost easily. The sealing of doors and windows includes the following aspects. First, the choice of sealing material. The good sealing strip is flexible and elastic, and has strong weather resistance. Even at minus 20°, it can maintain its toughness. In addition to the sealing strips, the doors and windows need to be treated with special processes, and the external noise is gone.


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