First, look at the price: in general, high-quality aluminum alloy doors and windows due to high production costs, the price is about 30% higher than that of poor quality aluminum alloy doors and windows. Some aluminum doors and windows are made of aluminum alloy with yield strength less than 8.0 mm.

The thermal insulation broken bridge aluminum alloy window is an improved type based on the old aluminum alloy window in order to improve the thermal insulation performance of the door and window. The aluminum alloy profile is divided into two parts by strengthening the nylon spacer, which blocks the heat conduction of aluminum. The thermal insulation of the aluminum alloy directly affects the durability of the window.

The window has brought bright and vital energy to the room. In the cold winter, the window has also become the heat preservation barrier of the room. Its sealing performance has become an important index for people to choose the window. In the past, people may pay more attention to its opening performance when they choose a window. In fact, if you want to understand its thermal insulation performance, window material, glass Hardware and so on are essential elements,

In addition, it is better to choose the products of regular aluminum alloy door and window manufacturers, and the products not processed according to the standard are not easy to meet the standard. In terms of thermal insulation and sealing performance, the new type of bridge breaking energy-saving aluminum alloy window is leading the fashion. This kind of profile adopts double threading technology, and reinforced nylon is used to separate the inside and outside of the aluminum window frame to avoid the exchange of internal and external energy. Among them, the wall thickness of aluminum alloy is very important. Generally, the wall thickness of general windows is more than 1.2 mm, and the wall thickness of high-grade energy-saving aluminum alloy windows can reach 1.8-2.0 mm, making winter more warm.

The outstanding advantages of thermal insulation bridge broken aluminum alloy doors and windows are light weight and high strength; environmental protection and energy saving, good thermal insulation, fire resistance, good atmospheric corrosion resistance, high comprehensive performance, long service life, a variety of color selection, good decoration effect, the use of high-grade bridge cutoff aluminum alloy doors and windows, is the first choice for high-grade building windows.

Second, look at the processing: high quality aluminum alloy doors and windows, fine processing, exquisite installation, good sealing performance, switch freely. Poor quality aluminum alloy doors and windows, blind selection of aluminum profile series and specifications, rough processing, saw cutting instead of milling processing, not according to the requirements of installation, poor sealing performance, switch is not free, not only air and rain leakage and glass burst phenomenon, but also encounter strong wind and external force, it is easy to pull parts or glass scraping or falling, damage and injury.
At present, there are many high-end brands in the market, such as Beijing Feitian door and window products Co., Ltd., Meritor, senying, etc., with the price of more than 1000 yuan, the price of medium-grade brand is about 800-900 yuan, and the price of low-grade products is about 500-600 yuan. According to experts, the price of this kind of broken bridge aluminum alloy window should be at least 600 yuan, and the quality is relatively reliable, because the inferior product with lower price may use plastic to replace aluminum alloy in the middle of broken bridge. One is not strong, the other is thermal expansion and cold contraction, which reduces the thermal insulation coefficient.

High quality and qualified broken bridge doors and windows are inseparable from high-quality double insulating glass. In the past, the windows were made of single-layer glass or ordinary double-layer glass. In recent years, insulating glass has appeared in China. In fact, insulating glass was invented by Americans in 1865. At that time, it was used in the army. Due to its superior performance in heat insulation, sound insulation, sealing, frost prevention and dust prevention, it has been recognized by all countries in the world. In Beijing, there are regulations that windows near the road should be hollow glass. Insulating glass is to seal the edges of two or more pieces of glass by adding desiccant inside the aluminum alloy spacer bar. The static dry gas is formed between the glass and has certain vacuum performance. Its main materials are aluminum alloy spacer bar, corner bolt, butyl rubber, environmental protection silicone rubber and desiccant. The high-grade insulating glass produced by Feitian doors and windows adopts bending insulating glass. There is only one joint between the aluminum strips between the two pieces of glass, which greatly improves the thermal insulation performance. According to the experts of Feitian doors and windows, the sealing and thermal insulation performance of insulating glass is very good, mainly due to its special material. It is very simple to identify whether the insulating glass is qualified in winter. As long as it is frozen inside and outside, if it is frozen, it is unqualified. Because the insulating property of insulating glass is that the silicone glue used can prevent water vapor from seeping into the insulating glass; butyl rubber can stick to two pieces of glass to make it tightly sealed; there is desiccant in the aluminum alloy spacer strip, which can absorb moisture. Generally speaking, the effective life of insulating glass is 8-10 years. In the process of its use, water vapor may seep into the insulating glass and water droplets may appear. However, this is a long process. According to the state regulations, if the insulating glass is used for five years, the water vapor can be regarded as qualified products. At present, the insulating glass of some high-grade doors and windows brands in the market can be used at ease. Beijing Feitian door and window products Co., Ltd. is a professional manufacturer which introduces Lisec large-scale production and processing center to produce and process insulating glass. The production process is strictly controlled, and the product quality can be imagined. But some small factory's insulating glass will produce inferior products, its so-called insulating glass is just two pieces of glass simply fixed together, consumers should still carefully distinguish, do not want to save money and affect the winter insulation oh.
