What is the difference between broken aluminum doors and windows and traditional doors and windows? Just look at it.

First of all, from the definition, the difference between the two:

Aluminum alloy doors and windows refer to doors and windows with aluminum alloy extruded profiles as frames, stiles and fans, referred to as aluminum alloy doors and windows for short. Aluminum alloy doors and windows include wood-plastic composite doors and windows with aluminum alloy as the stress bar (the bar bears and transmits self-weight and load), which is called aluminum-wood composite doors and windows and aluminum-plastic composite doors and windows for short. The quality of aluminum alloy doors and windows can be judged from the selection of raw materials (aluminum profiles), the quality of aluminum surface treatment and internal processing, and the price of aluminum alloy doors and windows.

Broken bridge aluminum, also known as thermal insulation broken bridge aluminum profile, thermal insulation aluminum profile, broken bridge aluminum profile, broken cold and hot bridge profile, broken bridge aluminum-plastic composite profile. It is an upgraded product of aluminum alloy doors and windows, and its performance is better than that of ordinary aluminum alloy profiles. The "bridge" in the name "Broken Bridge Aluminum" refers to the "hot and cold bridge" in the sense of materials science, and the word "broken" means action, that is, "breaking the hot and cold bridge". Specifically, because aluminum alloy is a metal and conducts heat quickly, aluminum alloy can be a "bridge" to transfer heat when the temperature difference between indoor and outdoor is very large. Using this material for doors and windows has poor heat insulation performance. Breaking the bridge aluminum means breaking the aluminum alloy from the middle. It uses hard plastic to connect the broken aluminum alloy into a whole. We know that the thermal conductivity of plastic is obviously slower than that of metal, so heat will not easily pass through the whole material, and the thermal insulation performance of the material will become better. This is the origin of the name "broken bridge aluminum (alloy)".

Second, compared with aluminum alloy doors and windows, the characteristics of broken bridge aluminum include:

1. Broken bridge aluminum has good thermal insulation performance. The inner and outer borders of the thermal insulation profile are flexibly combined, and the borders are in the form of one rubber strip, two wool strips and three seals, which are tightly sealed, excellent in air tightness and water tightness and excellent in thermal insulation performance; The window sash is made of hollow glass, which makes the window truly reflect the excellent functions of sound insulation, heat insulation and heat preservation, and saves a lot of heating and cooling expenses. The heat transfer coefficient K is below 2.23-2.94 W/㎡ k, and the energy saving effect is remarkable. The cost of energy saving for several years is enough to make up for the previous investment.

4. Waterproof function of broken bridge aluminum. Based on the principle of pressure balance, a structured drainage system is designed. The downward slope is designed as a ladder with a drain, which has smooth drainage and good water tightness.

3. Broken bridge aluminum should prevent condensation and frost. Broken bridge aluminum profile can realize triple sealing structure of doors and windows, reasonably separate water vapor cavities, successfully realize equal pressure balance of gas and water, significantly improve the water tightness and air tightness of doors and windows, and achieve the effect of bright windows and clean windows.

4. Design of mosquito-proof aluminum screen window for broken bridge. Invisible screen window, which can be installed and used inside and outside, is especially suitable for mosquito-infested areas in the north.

5. Anti-theft and anti-loosening device for broken bridge aluminum. Equipped with a unique multi-point hardware lock to ensure the stability and safety of windows in use.

6. Broken bridge aluminum noise and sound insulation. Its structure has been carefully designed and closely connected. The test results show that the sound insulation capacity of the air can reach 30-40 dB, which can ensure that residents within 50 meters on both sides of expressway are not disturbed by noise, and can also ensure the tranquility and warmth of the room when it is adjacent to downtown.

The fireproof function of broken bridge aluminum. Aluminum alloy is a metal material and will not burn.

8. Broken bridge aluminum. Sandstorm resistance. The inner frame straight material adopts hollow design, which has strong wind pressure deformation resistance and good earthquake resistance. Can be used in high-rise buildings and civil houses, and can design large-area windows with large lighting area; The air tightness of this kind of window is better than that of any aluminum window or plastic window, and the indoor windowsill and floor can be guaranteed to be dust-free in areas with heavy wind and sand.

? Broken bridge aluminum has high strength, no deformation and no maintenance. Broken bridge aluminum window has high tensile and shear strength, strong thermal deformation resistance and durability. Broken bridge aluminum profile is not easy to be corroded by acid and alkali, yellow and faded, and almost does not need maintenance.

⒑ Broken bridge aluminum has many colors.

(1) Broken bridge aluminum green building materials, circular economy. Broken bridge aluminum doors and windows not only do not produce harmful substances in the production process, but all materials can be recycled, which is a green building material and environmental protection product, in line with the sustainable development of mankind.

5] Broken bridge aluminum has various opening forms, which are comfortable and durable. There are flat type, inclined type, hanging type, push-pull type, flat type and inclined type. , suitable for public buildings, residential quarters and municipal engineering; High-quality hardware fittings are durable, the operating handle is humanized, beautiful and comfortable, and it is convenient and flexible to open. Every action has been tested, and the number of fatigue tests has reached tens of thousands. Push and pull easily and silently, mature and perfect door and window processing technology, high-precision program control processing center for production, stable quality is guaranteed.

Of course, aluminum alloy doors and windows have its market space because of their low prices, but this market share will decrease year by year, and more and more families will use energy conservation and environmental protection. Broken aluminum doors and windows are gradually entering more families.
