Advantages of aluminum-plastic aluminum doors and windows

Aluminum-plastic aluminum doors and windows are generally about one square 300 yuan! It has the following advantages.

Good thermal insulation performance

The inner and outer frames of thermal insulation profiles are flexibly combined, and the frames are in the form of one rubber strip, two tops and three seals, which are tightly sealed, excellent in air tightness and water tightness and excellent in thermal insulation performance; The window sash adopts hollow glass structure, which makes the window truly embody 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/2k, and the energy saving effect is remarkable. The cost of energy saving for several years is enough to make up for the previous investment.

Waterproof function

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.

Anti-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.

Design of mosquito-proof screen window

Invisible screen window, which can be installed and used inside and outside, is especially suitable for mosquito-infested areas in the north.

Anti-theft and anti-loosening device

Equipped with standard hardware locks to ensure the stability and safety of windows in use.

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 the expressway are not disturbed by noise, and can also ensure the tranquility and warmth of the room when it is adjacent to downtown.

Fire protection function

The aluminum alloy is made of metal, and the insulation strip is made of PA66GF25 (commonly known as nylon insulation strip), which is nonflammable and has good high temperature resistance.

Anti-wind sand and wind pressure

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.

High strength, no replacement, 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.
