Understanding aluminum windows and doors, these are the 15 basics you must know!

1. What are the characteristics of aluminum alloy doors and windows?

Advantages of broken bridge aluminum alloy doors and windows: corrosion resistance, good weather resistance, does not contain formaldehyde and other harmful substances, superior thermal insulation performance, in line with national energy saving and environmental protection policies, while according to the interior design and exterior wall design to do different color styles to meet the different needs of customers.

Doors and windows in the production process, manufacturers will also use oxidation, electrophoresis, porcelain swimming, powder coating, fluorocarbon, wood grain transfer printing and other surface treatment methods, the formation of aluminum alloy antioxidant, corrosion-resistant protective film, to improve the service life of aluminum alloy doors and windows.

2. Characteristics of aluminum alloy door and window profiles?

Aluminum alloy profile is a profile mainly made of aluminum with the addition of some alloying elements to enhance strength and hardness.

Aluminum alloy can be divided into aluminum-silicon alloy, aluminum-copper alloy, aluminum-magnesium alloy, aluminum-titanium alloy, aluminum-zinc alloy and aluminum-rare-earth alloy according to its chemical composition. The general raw material alloy is aluminum ingot, aluminum ingot melted into aluminum rods through the heating and extrusion into doors and windows of aluminum bars, room temperature is not easy to oxidation, not easy to rust, but the use of time will react with hydrogen. In order to increase the service life need to be surface spraying anti-oxidation treatment, after processing the service life of aluminum alloy profiles can reach more than 30 years.

3. What are the advantages of broken bridge aluminum alloy profile?

Ordinary aluminum profiles have a single color, the whole is a conductor, heat transfer and heat dissipation is relatively fast, heat preservation and insulation effect is general. Broken bridge aluminum profile is the use of PA66 nylon heat insulation strips connecting the two ends to form a heat insulation layer, the temperature difference between inside and outside is not the same, reduce heat transfer, play a role in heat preservation and energy saving. It can be made in two colors, and the inside and outside colors can be chosen at will, with beautiful appearance and good performance. At the same time, the insulated broken bridge aluminum profile can realize the three sealing structures of doors and windows, reasonably separating the water vapor cavity, and successfully realizing the isobaric pressure balance of gas and water, which significantly improves the watertightness and airtightness of doors and windows.
4. What is insulating glass?

Between the glass and glass of insulating glass, a certain space is left, and the frame is filled with desiccant to ensure the dryness of the air between the glass pieces. Hinges, door locks and other frequently moving hardware, loosening should be tightened immediately. When the door lock does not work, you can add an appropriate amount of lubricant to the keyhole, such as the end of a pencil lead for lubrication.
5. What is laminated glass?

Laminated glass is made of two or more pieces of glass, sandwiched between one or more layers of organic polymer interlayer, after a special high-temperature pre-pressure (or vacuum) and high-temperature and high-pressure process, so that the glass and the interlayer is permanently bonded to a composite glass product. Even if the glass is broken, the fragments will be glued to the film, and the surface of the broken glass will remain neat and smooth. Compared with other glass, it has the performance of shock-resistant, anti-theft, bullet-proof and explosion-proof, which can effectively prevent the occurrence of debris stabbing and penetrating falling events and ensure personal safety.

6.What is LOW-E glass?

LOW-E glass, also known as low-e glass, is a film coated on the surface of the glass to keep the ultraviolet rays outside, and its coating layer has the characteristics of high transmittance of visible light and high reflection of medium and far-infrared rays, which makes it have excellent heat insulation and good light transmittance and good ultraviolet protection compared with the ordinary glass and the traditional architectural coated glass.

7. Advantages and disadvantages of offline LOW-E and online LOW-E?

Online LOW-E glass: can be used as a single piece, can be laminated, can be bent steel, the price is cheaper than offline, but the color is single, only high-transparency and blue-gray two colors, the use of single-glass thermal insulation performance is poor.

Offline LOW-E glass: composed of four or more layers of film, a variety of varieties, according to different climatic characteristics can be made in high, medium and low transmittance products, the color of silver gray, light gray, light blue and colorless transparent and so on.

Product adaptability: In foreign countries, online Low-E glass is mainly used in low-rise civil buildings. Offline Low-E glass is mainly made into tempered insulating glass, used in commercial buildings and other high-grade buildings.

8. What is insulating glass louver?

It is to install metal aluminum sheet inside the insulating glass, using magnetic force to control, can adjust the angle at will, so that all the light transmittance, semi-transparent or shading, and at the same time can pull up all the louvers into all the light transmittance window. Can be used 20,000 times about 20 years, the product not only saves the use of space, but also to achieve the purpose of shading, but also has thermal insulation and anti-noise function, clean, hygienic, do not need to wash, at the same time, can bring a novel visual effect.
9. What are the different types and characteristics of aluminum alloy doors and windows?

Aluminum windows and doors mainly include sliding windows, casement windows, top-hung windows, inward opening windows and fixed windows.

Sliding doors and windows: two doors and windows in the same plane, the fan can be pushed and pulled to the left and right horizontal doors and windows.

Casement windows and doors: that is, the doors and windows are open forward or backward, open the fan is not in the same plane, will take up a certain amount of space in the wall to the indoor or outdoor doors and windows.

Upper-hung windows: the upper end of the fixed, open fan tilted open, openings in the bottom.

Inward opening windows: the use of European standards, open to the interior, natural ventilation, people are not at home when the doors and windows can also be opened, the use of high-level time and then do not have to worry about smashing into the downstairs. Fixed windows and doors: windows and doors that cannot be opened.
10. What are system windows and doors?

System windows and doors originated in Europe, and through years of use, the airtightness and energy-saving effect of windows and doors are taken into account in the design. System windows and doors are used by the system company to adopt the overall door and window system solutions, the performance of the product, the quality of the indicators to make a clear commitment to the need to consider the watertightness, airtightness, wind pressure, mechanical strength, heat insulation, sound insulation, anti-theft, sunshade, weather resistance, operation feel and a series of important functions, but also to consider the comprehensive results of the performance of the various aspects of the equipment, profiles, fittings, glass, adhesive, seals.
11. What is the standard wall thickness of aluminum alloy window and door profiles?

Aluminum window profile wall thickness of the main stress parts is not less than 1.4mm, high-level to reach more than 20 layers, you can choose to increase the thickness of the profile; heavy-duty sliding door profile wall thickness of the main stress parts is not less than 2.0mm; this is the national standard in line with the requirements of the wind pressure resistance, a single door or window more than 3 ~ 4 square can be thickened, too large can be added to the column to increase its physical strength.

12. What are the main hardware accessories for aluminum windows and doors?

The main hardware accessories of casement windows: linkage handle, sliding brace, hinges, lock point, lock box, back button lock, heaven and earth locks, etc.; the main hardware accessories of inward opening and inverted windows: linkage handle, linkage rod, linkage, etc.

13. What is the difference between hot bending and tempered bending?

Hot bending glass is the glass is heated to a softening temperature, and then rely on self-weight or external forces will be bent to form and naturally cooled after the formation; bent tempered glass is formed in the curvature of the molding of the special equipment made of fast air-cooled. Hot bending glass does not belong to the safety glass, bent glass belongs to the safety glass.

14. Tempered glass, semi-tempered glass features?

Tempered glass is 4-5 times stronger than ordinary glass, after broken into small particles, belonging to the safety glass; can withstand sudden temperature changes of 250 ~ 320 degrees, the disadvantage of the existence of the phenomenon of self-detonation, can not be cut, tempered after the reduction of flatness. Semi-tempered glass strength between ordinary glass and tempered glass, not easy to self-detonation, good flatness, but heat and impact resistance is inferior to tempered.

15. How to identify high-quality aluminum windows and doors?

When buying doors and windows, try to choose products with good market reputation and perfect after-sales system. Choose a big brand, in terms of profiles, equipment, technology, standards and other aspects are guaranteed, but also less prone to problems in quality and workmanship, more trustworthy.
