Technical features of broken bridge aluminum alloy doors and windows.

Technical features editor

The window brings light and vitality to the bedroom, and in the cold winter, the window has become the insulation barrier of the bedroom, its sealing performance has become an important index for people to choose the window, people used to choose the window, may pay more attention to its opening performance, in fact, to understand its insulation performance, window material Glass, hardware and so on are all essential elements.

The aluminium alloy window of insulated bridge is an improved type which is based on the old aluminium alloy window to improve the insulation performance of doors and windows. The material and quality of the reinforced nylon spacer will directly affect the durability of the heat insulation broken bridge aluminum alloy window.

The outstanding advantages of aluminium alloy doors and windows are high strength, good thermal insulation, rigidity, good fireproof, large lighting area, good atmospheric corrosion resistance, high comprehensive performance, long service life, good decorative effect. The use of high-grade aluminium alloy doors and windows with broken bridge partition is the preferred product for high-grade building windows.

Material for use: Aluminum profiles, thickness, strength and oxide film used for high-quality aluminum alloy doors and windows should conform to the relevant national standards, wall thickness should be more than 1.2 mm, tensile strength should reach 157 Newtons per square meter, yield strength should reach 108 Newtons per square millimeter, oxide film thickness should reach 10 microns. If we fail to meet the above criteria, we should not use inferior aluminum alloy doors and windows.

Look at processing: high quality aluminum alloy doors and windows, fine processing, installation, sealing performance is good, switch freely. Bad quality aluminium alloy doors and windows, blindly select series and specifications of aluminium profiles, rough processing, cutting instead of milling, not according to requirements for installation, poor sealing performance, switch not free, not only air leakage and rain leakage and glass burst, but also encountered strong wind and external forces, easy to push and pull parts or glass scrape off or Falling down, destroying things and hurting people.

Look at the price: In general, high-quality aluminum alloy doors and windows because of high production costs, the price than poor aluminum alloy doors and windows to about 30% higher energy. Some aluminium alloy doors and windows with wall thickness of only 0.6-0.8 mm are unsafe because their tensile strength and yield strength are much lower than the relevant national standards.

In addition, the best choice of regular aluminum alloy doors and windows manufacturer's products, not according to standard processing products are not easy to reach the standard.

Bridge material

In terms of thermal insulation and sealing performance, the new energy saving aluminum alloy window is leading the way. The profiles are made of double piercing strips, and reinforced nylon is used to isolate the inside and outside of the aluminum window frames for the exchange of internal and external energy. Among them, the wall thickness of aluminum alloy is very important. Generally, windows are at least 1.2 mm thick. The wall thickness of high-grade energy-saving aluminum alloy windows can reach 1.8-2.0 mm, which makes the winter warmer.

Speaking of the price of aluminum alloy windows, there are currently 78 high-end brands on the market, such as Mercedes, Senying, Jinan VEKA, Schweiler, Baoshi, etc., the price of more than 1000 yuan, the price of middle-grade brands in 800 yuan to 900 yuan, and the price of low-grade products in 500 or 600 yuan. Experts introduced that consumers to buy this kind of broken bridge aluminum alloy window, the price at least 600 yuan above the quality is relatively reliable, because the price of inferior products may be lower in the middle of the broken bridge with plastic instead of aluminum alloy, one is not solid, the other is hot expansion and cold shrinkage, reducing the thermal insulation coefficient.

Double glazing

When it comes to windows, we can not help but say that glass, the previous windows, are made of single-layer glass or ordinary double-layer glass, in recent years in China there has been a hollow glass. Hollow glass was invented by Americans in 1865. It was used in the army at that time. Because of its superior performance in heat insulation, sound insulation, sealing, frost prevention, dust prevention and so on, it was recognized by all countries in the world. In Beijing, there is a rule that windows should be hollow glass as long as they are near the road.

Hollow glass is two or more pieces of glass edges sealed together, the glass between the formation of static dry gas, and a certain vacuum performance. The main materials are aluminum alloy spacer, corner bolt, butyl rubber, polysulfide glue and desiccant.

According to Mercedes experts, hollow glass sealing, insulation performance is very good, mainly because of its special material, in winter to identify whether the qualified hollow glass is very simple, as long as it is frozen inside and outside, if there is frozen is not qualified. Because the insulating property of the hollow glass is that the polysulfide glue it uses can prevent water vapor infiltration; butyl glue can stick to two pieces of glass to make it tightly sealed; aluminum alloy clapboard has a desiccant, play a role in moisture absorption.

Generally speaking, the effective life of hollow glass is 8-10 years, in its use process, there may be water vapor infiltration, water droplets, but this is a long process, the state stipulates that five years of use of hollow glass water vapor can be regarded as qualified products.

At present, some high-end door and window brand hollow glass can be safely used, such as Mercedes, Garbo, Schweiler and other brands. And some small factory hollow glass will produce inferior products, the so-called hollow glass is simply fixed together two pieces of glass, consumers should be careful to distinguish, do not affect the winter heat preservation oh.
