1. What are ordinary aluminum alloy profiles?
There is no air layer between the inside and the outside, and the surface is sprayed with anti-corrosion treatment.
2. What is a broken bridge aluminum alloy profile? What are its advantages?
The principle of the broken bridge type aluminum alloy window is to use heat insulation strips to separate and tightly connect the two layers of indoor and outdoor aluminum alloys into a whole to form a new heat-insulating aluminum profile. The inner and outer colors can be selected at will, beautiful and beautiful. The performance is good and the energy-saving effect is formed.
3. What is the difference between ordinary aluminum alloy profiles and broken bridge aluminum alloy profiles
Ordinary aluminum profile is entirely a conductor, and the heat transfer and heat dissipation are relatively fast;
The thermal insulation strip in the aluminum profile of the broken bridge has low thermal conductivity, forming a cold and hot broken bridge, heat preservation and heat insulation, and diversified colors.

5. What is laminated glass? When to use laminated glass?
Laminated glass is composed of two or more pieces of glass with one or more layers of organic polymer interlayer between them. After a special high-temperature pre-pressing (or vacuum) and high-temperature and high-pressure process, the glass and the interlayer A composite glass product that is permanently bonded as a whole. Even if the glass is broken, the shards will be stuck on the film, and the surface of the broken glass remains clean and smooth. This effectively prevents the occurrence of debris piercing and penetrating fall incidents, and ensures personal safety.
Laminated glass is recommended for aluminum alloy doors and windows in the following situations:
①Glass for floor spring door
② The area of a single piece of window glass is greater than 1.5 m2, and the area of a single piece of glass of framed door is greater than 0.5 m2;
③ Floor-to-ceiling windows with the bottom edge of the glass less than 500mm away from the final decoration surface;
④ Frameless door and window glass;
⑤ Entrance and exit doors of public buildings;
⑥ The door of kindergarten or other children’s activity place;
⑦tilt windows, skylights;
⑧the exterior windows of 7-story and above buildings.
6. What is LOW-E glass? What are its advantages?
LOW-E glass is also known as low-radiation heat-reflective glass, which is coated with a film on the surface of the glass to block ultraviolet rays from the outside, increase or decrease the indoor and outdoor temperature, and have a protective effect on the human body.
7. What is hollow glass? What is the material of the page? What is the service life?
It is to install a metal aluminum sheet in the hollow glass, which is controlled by magnetic force. It can be used 20,000 times for about 20 years. The advantage is that it is clean, hygienic and does not need to be cleaned.
8. What are the advantages of insulating glass, LOW-E glass and laminated glass?
Insulating glass is good for energy saving; LOW-E glass is anti-ultraviolet; laminated glass is safe.
9. What is the wall thickness of the aluminum alloy window profile? What is the wall thickness of the aluminum alloy door profile?
The wall thickness of the main force-bearing part of the window profile is not less than 1.4mm, and the upper level reaches more than 20 layers. The thickness of the profile can be increased; the wall thickness of the main force-bearing part of the door profile is not less than 1.8mm, which is the national standard that meets the requirements of wind pressure resistance. Single doors and windows over 3-4 square meters can be thickened, and columns can be added if they are too large.
10. What are system doors and windows? Where did it originate?
The system doors and windows originated in Europe. Through years of use, the airtightness and energy-saving effects of the doors and windows were considered in the design. System doors and windows are the overall door and window system solutions adopted by the system company, and make clear commitments to product performance and quality indicators. Water tightness, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, anti-theft, and sunshade need to be considered. For a series of important functions such as, weather resistance, operating feel, etc., the comprehensive results of the performance of equipment, profiles, accessories, glass, viscose, and seals must also be considered.
11. What is the warranty period of insulating glass? What circumstances fall within the scope of the warranty, and what circumstances do not fall within the scope of the warranty?
The national standard for 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 covered by the warranty.
12. What is the heat transfer coefficient? What is the heat transfer coefficient of ordinary aluminum alloy doors and windows? What is the heat transfer coefficient of broken bridge aluminum alloy doors and windows? What is the heat transfer coefficient of the aluminum alloy doors and windows of the system?
That is, during the detection, the internal temperature is passed through the time to see the speed of the internal temperature to the outside, and the heat transfer value is obtained after the passage of 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 the aluminum alloy doors and windows of the system is about 2.0-2.5.
13. What are sliding doors and windows? What are side-hung doors and windows? What is the upper hanging window? What is the inverted window? What is a fixed window?
Sliding doors and windows: one of the two sliding doors and windows.
Casement doors and windows: the opening and closing of the window sashes move along a certain horizontal direction, so it is called “casement windows.
Top-hung window: A window with a hinge (hinge) installed on the upper side of the window and opening inward or outward.
Inwardly opening and inverted windows: It adopts European standards and can be opened horizontally or inverted. That is, the lower part of the window does not move, and the upper part is inclined indoors for natural ventilation. The doors and windows can be opened when people are not at home.
Fixed doors and windows: Generally, the window frame is directly inlaid with glass or the window sash is fixed on the window frame and cannot be opened.
14. What are the advantages of casement windows, sliding windows, and inwardly opening and inverted windows?
The casement window is the traditional opening method in China, referred to as the national standard;
The sliding window is simple and does not occupy space; it is commonly used in China.
The inverted window adopts European standards and is designed in a system that allows people to ventilate naturally when they are not at home. Rain cannot enter the house. In spring and autumn nights, they can sleep with the window open, and it is not easy for a thief to open it.
15. What are the main hardware accessories for sliding windows? What are the main hardware accessories for casement windows? What are the main hardware accessories for inward opening and inward inverting?
The main hardware accessories of sliding windows: pulleys, hook locks, crescent locks;
The main hardware accessories of casement windows: linkage handles, sliding supports, hinges, wind supports, etc.;
The main hardware accessories of the inwardly opening and inverted windows: linkage handles, linkages, linkages, etc.
16. What are the key processes in the processing of side-hung aluminum alloy doors and windows?
Blanking: guarantee geometric size;
Group angle: prevent rainwater from entering;
Assembly of accessories;
The appearance should be beautiful.
17. In order to ensure the quality of doors and windows during transportation, how are they packed?
It is packaged with special paper for doors and windows; the aluminum-wood windows are fixed around with corners, so that there is no friction space between the profile and the profile, and finally put in a wooden box.
18. What is the warranty period for doors and windows? What circumstances are not part of the work covered by the warranty?
The national standard for the warranty period of doors and windows is two years, and damage caused by human factors is not within the scope of the warranty period.
19. What is the service life of the glue?
