1, what is the ordinary aluminum alloy profile? Is the internal and external communication without air layer, the surface to do spraying anti-corrosion treatment. The principle of the broken bridge aluminum alloy window is to use the heat insulation strip to separate and closely connect the indoor and outdoor two layers of aluminum alloy into a whole, forming a new type of heat insulation aluminum profile, the inside and outside color can be arbitrarily selected, beautiful, good performance, forming an energy-saving effect. 3. What is the difference between ordinary aluminum alloy profile and broken bridge aluminum alloy profile? The whole ordinary aluminum profile is a conductor, and the heat transfer and heat dissipation are relatively fast; the thermal conductivity of the heat insulation strip in the broken bridge aluminum profile is low,

1. What is an ordinary aluminum alloy profile?
is that there is no air layer between inside and outside, and the surface is sprayed with anti-corrosion treatment.
2. What is a broken bridge aluminum alloy profile? What are its advantages?

. The color of the interior and exterior can be selected arbitrarily, with beautiful appearance and good performance, forming an energy-saving effect.
3. What is the difference between ordinary aluminum alloy profile and broken bridge aluminum alloy profile?
Ordinary aluminum profile is the whole conductor, heat transfer and heat dissipation are relatively fast;
The thermal insulation strip in broken bridge aluminum profile has low thermal conductivity, forming cold and hot broken bridge, thermal insulation and color diversification.
4. What is insulating glass? What is the K value of aluminum doors and windows with broken bridges? What is the K value of ordinary aluminum doors and windows? What is the sound insulation?
Insulating glass is to seal two or more pieces of glass edges together. The glass is treated with desiccant. The temperature difference between the inside and outside of the glass is not the same as
. The K value of
hollow glass for broken bridge aluminum doors and windows is about 2.7-3.0; The K value of
hollow glass for ordinary aluminum doors and windows is about 3.5-5.0; The K value of hollow glass for aluminum doors and windows of
system is about 2.0-2.5;
5, what is laminated glass? Under what circumstances do you use laminated glass?
laminated glass is made up of two or more pieces of glass, sandwiched between one or more layers of organic polymer intermediate film, after special high temperature preloading (or
vacuum) and high temperature and high pressure process, the glass and intermediate film permanent bonding into one composite glass products. Even if the glass is broken
, the fragments will be stuck to the film, and the surface of the broken glass will remain clean and smooth. This effectively prevents the occurrence of debris prick and penetration drop
, ensuring personal safety.
Aluminum alloy doors and windows are recommended to use laminated glass in the following situations:
①, floor spring door glass
②, window single glass area greater than 1.5 m2, framed door single glass area greater than 0.5 m2;
③, floor-to-ceiling windows with glass bottom edge less than 500mm from the final decoration surface;
④, frameless door and window glass;
⑤, entrance and exit doors of public buildings;
⑥, doors of kindergartens or other children's activities;
⑦, inclined windows and skylights;
⑧, exterior windows of buildings with 7 floors and above.
6. What is LOW-E glass? What are its advantages?
LOW-E glass, also known as low radiation heat reflective glass, is that the glass surface is coated with a layer of film to block ultraviolet rays outside, improve or reduce the temperature outside the room
, which is a protective effect on the human body.
7. What is the hollow hundred-page glass? What is the material of the sheet? What is the service life?
is to install the metal aluminum sheet in the hollow glass, which is controlled by magnetic force. Can be used 20000 times for about 20 years, the advantage is clean, hygienic,
without cleaning.
8, insulating glass, LOW-E glass, laminated glass three, what are the advantages?
Insulating glass energy saving good; LOW-E glass UV protection; laminated glass safety.
9. How many years is the warranty period of insulating glass? What is within the scope of warranty and what is not?
The national standard of the warranty period of insulating glass is 15 years; the service life is 15-20 years, and there are examples in Europe.
If the glass is damaged due to improper use of human factors, it is not within the scope of the warranty.
10. What are system doors and windows? Where did it originate?
system doors and windows originated in Europe. Through years of use, the airtightness and energy-saving effects of doors and windows were considered in the design. The system doors and windows are the integral door and window system solution adopted by
system company, which makes a clear commitment to the performance and quality indicators of the product. a series of important functions of
, such as watertight
, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, anti-theft, sunshade, weather resistance, operation feel, etc. need to be considered, also consider the comprehensive results of the performance of equipment, profiles, accessories, glass, glue, and seals.
11, aluminum alloy window profile wall thickness is how much? aluminum alloy door profile wall thickness is how much? The wall thickness of the main stressed parts of
window profile shall not be less than 1.4mm, and the high-rise layer shall reach more than 20 layers, so you can choose to increase the thickness of the profile. The wall thickness of the main
stressed parts of the door profile shall not be less than 1.8mm, which is the national standard to meet the requirements of wind pressure resistance. Single doors and windows can be thickened if they exceed 3-3-3-4-4-4-4 square meters, and 3-4-3-150, and 3.
12, what is the heat transfer coefficient? What is the heat transfer coefficient of ordinary aluminum alloy doors and windows? Is the heat transfer coefficient of broken bridge aluminum alloy doors and windows more
less? What is the heat transfer coefficient of aluminum alloy doors and windows of the system?
is the speed of outward conduction of internal temperature through time, and the heat transfer value is obtained through time and temperature. The heat transfer coefficient of
ordinary aluminum alloy doors and windows is about 3.5-5.0; The heat transfer coefficient of
broken bridge aluminum alloy doors and windows is about 2.5-3.0; The heat transfer coefficient of
system aluminum alloy doors and windows is about 2.0-2.5.
13. What are sliding doors and windows? What are casement doors and windows? What are hanging windows? What are internal inverted windows? What are fixed
windows?
sliding doors and windows: one of the two doors and windows is pushed and pulled to the left and right.
casement doors and windows: The sash opening and closing moves along a certain horizontal direction, so it is called "casement window".
