1. What are ordinary
aluminum alloy profiles? That is, there is no air layer between the 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 principle of the broken bridge type aluminum alloy window is to use heat insulation strips to separate and tightly connect the two layers of aluminum alloy inside and outside into a whole, forming a new heat-insulating
aluminum profile. The inner and outer colors can be selected at will, beautiful and beautiful. Good performance and energy saving effect. 3. What is the difference between ordinary aluminum alloy profile and broken bridge aluminum alloy profile? Ordinary aluminum profile is a conductor, heat transfer and heat dissipation are faster; the thermal conductivity of the heat insulation strip in the broken bridge aluminum profile is low, forming a cold and hot broken bridge, Thermal insulation, diversified colors. 4. What is insulating glass? What is the K value of the aluminum doors and windows of the distribution bridge? What is the K value for ordinary aluminum doors and windows? How much is the sound insulation? Insulating glass is to seal two or more glass edges together, and the glass is treated with a desiccant. The temperature difference between the inside and outside of the glass is different. Broken bridge aluminum doors and windows + insulating glass K value is about 2.7-3.0; ordinary aluminum doors and windows + insulating glass K value is about 3.5-5.0; system aluminum doors and windows + insulating glass K value is about 2.0-2.5; 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 film between them. After a special high-temperature pre-pressing (or vacuum) and high-temperature and high-pressure process, the glass and the interlayer Permanently bonded as a whole composite glass product. 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: ①, floor spring door glass ②, window single glass area is greater than 1.5m2, framed door single glass area is greater than 0.5m2; ③, the bottom edge of the glass is less than the final decoration surface 500mm floor-to-ceiling windows; ④, frameless windows and doors; ⑤, entrance and exit doors of public buildings; ⑥, doors of kindergartens or other children's activity places; ⑦, inclined windows, skylights; ⑧, external 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 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 protect 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, and the advantages are clean, hygienic, and no need to clean. 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 layer 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. The single door and window can be thickened if it exceeds 3-4 square meters, and the column can be added if it is 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 taken into account in the design. The system doors and windows are the overall door and window system solutions adopted by the system company, and make clear commitments to the 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 each link of equipment, profiles, accessories, glass, viscose, and seals must also be considered.
