1. What are ordinary aluminum alloy profiles?  

That is, there is no air layer connected inside and outside, and the surface is sprayed with anticorrosive treatment.  

2. What is a broken bridge aluminum alloy profile?What are its advantages?  

The principle of broken bridge aluminum alloy windows is to use heat insulation strips to separate and closely connect the two layers of aluminum alloy indoors and outdoors into a whole, forming a new type of heat-insulating aluminum profile. The internal and external colors can be arbitrarily selected, beautiful appearance, good performance, and energy-saving effect.  

3. What is the difference between ordinary aluminum alloy profiles and broken bridge aluminum alloy profiles?  

The entire ordinary aluminum profile is a conductor, and the heat transfer and heat dissipation are relatively fast.；  

The thermal insulation strips in the aluminum profiles of broken bridges have low thermal conductivity, forming hot and cold broken bridges, thermal insulation, and diversified colors.  

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?  

Hollow glass is to seal the edges of two or more pieces of glass together, and the glass is treated with a desiccant, and the temperature difference between the inside and outside of the glass is different.  

Broken bridge aluminum doors and windows + hollow glass K value is about 2.7-3.0;  

Ordinary aluminum doors and windows + hollow glass K value is about 3.5-5.0;  

The K value of the system aluminum doors and windows + hollow glass is about 2.0-2.5;  

5. What is laminated glass?Under what circumstances is laminated glass used?  

Laminated glass is a composite glass product made of two or more pieces of glass with one or more layers of organic polymer intermediate film sandwiched between them. After special high-temperature pre-pressing (or vacuuming) and high-temperature and high-pressure process treatment, the glass and the intermediate film are permanently bonded into one.Even if the glass is broken, the fragments will be glued to the film, and the surface of the broken glass will still be kept clean and smooth.This effectively prevents the occurrence of debris stab wounds and penetrating falls, and ensures personal safety.  

Laminated glass is recommended for aluminum alloy doors and windows in the following cases：  

①glass for floor spring doors  

②、 The glass area of a single window is greater than 1.5m2, and the glass area of a single framed door is greater than 0.5m2.；  

③、 Floor-to-ceiling windows with the bottom edge of the glass less than 500mm from the final decoration surface；  

④、Frameless door and window glass；  

⑤、 Entrance and exit doors of public buildings；  

⑥. The door of a kindergarten or other children's activity place；  

⑦、 Inclined windows and skylights；  

⑧. The outer windows of buildings with 7 floors and above are opened.  

6. What is LOW-E glass?What are its advantages?  

LOW-E glass, also known as low-radiation heat-reflective glass, means that the surface of the glass is coated with a film to block ultraviolet rays from the outside and increase or decrease the indoor and outdoor temperature, which is a protective effect on the HUMAN body.  

7. What is hollow hundred-page 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 hollow glass, LOW-E glass, and laminated glass?  

Hollow glass is energy-saving and good; LOW-E glass is UV-proof; laminated glass is safe.  

9. What is the wall thickness of aluminum alloy window profiles?What is the wall thickness of the aluminum alloy door profile?  

The wall thickness of the main force part of the window profile is not less than 1.4mm, and the high-rise reaches more than 20 floors. You can choose to increase the thickness of the profile; the wall thickness of the main force part of the door profile is not less than 1.8mm, which is the national standard meets the requirements of wind pressure resistance. Single doors and windows can be thickened if they exceed 3-4 square meters, and columns can be added if they are too large.  

10. What is system doors and windows?Where did it originate?  

The system of doors and windows originated in Europe. Through years of use, the air tightness and energy-saving effects of doors and windows are taken into account in the design.System doors and windows are the overall door and window system solutions adopted by the system company to make a clear commitment to the performance and quality indicators of the product. It is necessary to consider a series of important functions such as water tightness, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, anti-theft, shading, weather resistance, and operating feel, as well as the comprehensive results of the performance of equipment, profiles, accessories, glass, viscose, and seals.
