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

Energy-saving doors and windows should be considered from the following aspects:

1. Material of doors and windows

Now 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 the thermal conductivity of iron and aluminum is very high, and a little heat will be dissipated, so the house is always cold in winter. In the past few years, plastic-steel windows and plastic windows were popular, but the windows of this material are not strong enough, easy to become brittle, and the safety can be imagined. Wooden windows have excellent energy saving and environmental protection performance, but wooden windows have their own defects, and they are also easy to burn, rot and crack, etc. At the same time, the price of wooden windows is not cheap. At present, the energy saving and environmental protection performance of broken bridge aluminum doors and windows is the best. It not only solves the shortcomings of high thermal conductivity of aluminum alloys, but also makes up for the disadvantages of low strength of plastic steel and plastic, and the price is relatively low compared to 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 glass is the most energy efficient? It should be low-e glass, which can filter out harmful light such as infrared rays, far infrared rays, and ultraviolet rays, and has a significant energy-saving effect. In recent years, the state requires high-rise buildings to use insulating glass, which is two layers of glass. But looking at the insulating glass on the market, it is plausible, it may just be a simple two-layer combination, and the real heat insulation effect has not been achieved.

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. Relying on glass alone cannot achieve the purpose of energy saving. The sealing performance of doors and windows is also an important parameter that affects energy saving. If there is a problem with the sealing of doors and windows, energy can also be easily lost. The sealing of doors and windows includes the following aspects. The first is the selection of sealing materials. A good sealing strip is flexible, elastic, and has strong weather resistance. Even at minus 20°, it can maintain its toughness. In addition to the sealing strip, the doors and windows also need to be treated with special processes, and the disturbing noise from the outside world will disappear.

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 craftsmanship of the doors and windows!
