Many of our direct customers need to buy doors and windows, or the who just entered the door and window industry, they even don’t know the basic way to open doors and windows?
So here, allow me to share 15 basis points of aluminum windows and door, let you know it easily
1. What are the characteristics of aluminum doors and windows?
Advantages of thermal break aluminum alloy doors and windows: Corrosion resistance, good weather resistance, free of formaldehyde and other harmful substances, superior heat insulation performance. At the same time, according to the interior design and external wall design, different color styles can be achieved to meet the different needs of customers.
In the production process of doors and windows, the manufacturer will use oxidation, electrophoresis, porcelain swimming, powder spraying, fluorocarbon, wood grain transfer and other surface treatment methods to form anti-oxidation and anti-corrosion protective film on aluminum alloy, so as to improve the service life of aluminum alloy doors and windows.
2. Characteristics of aluminum alloy door and window profiles
Aluminum alloy profile is mainly made of aluminum, adding some alloy elements to enhance strength and hardness.
According to the chemical composition, 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. The general raw material alloy is aluminum ingot. After melting into aluminum rod, aluminum ingot is extruded into aluminum strip for doors and windows by heating. It is not easy to oxidize and rust at room temperature, but it will react with hydrogen after being used for a long time. In order to increase the service life, it is necessary to spray anti-oxidation treatment on the surface.
The service life of processed aluminum alloy profiles can reach more than 30 years.
3. What are the advantages of thermal break aluminum alloy profiles?
Well, let’s see normal aluminum profile.
The color of ordinary aluminum profile is single, the whole is conductor, heat transfer and heat dissipation are relatively fast, and the effect of thermal insulation is general.
PA66 nylon insulation strip is used to connect the two ends of thermal break aluminum profile to form an insulation layer. The temperature difference between inside and outside is different, which can reduce heat transfer and play the role of heat preservation and energy saving.
It can be made in two colors. The color inside and outside can be selected at will. It has beautiful appearance and good performance. At the same time, the heat insulation broken bridge aluminum profile can realize the three-way sealing structure of doors and windows, reasonably separate the water vapor chamber, successfully realize the gas water isobaric balance, and significantly improve the water tightness and air tightness of doors and windows.
4. What is insulating glass/ double glass?
Insulating glass is to seal the edges of two or more pieces of glass together. The glass is treated with desiccant. The temperature difference between inside and outside of the glass is different. There is a certain space between the glass and the glass of the insulating glass, and the frame is filled with desiccant to ensure the dryness of the air between the glass sheets.
5. What is laminated glass?
Laminated glass is a kind of composite glass product with two or more pieces of glass sandwiched with one or more layers of organic polymer intermediate film. After special high-temperature preloading (or vacuuming) and high-temperature and high-pressure process, the glass and the intermediate film are permanently bonded into one. Even if the glass is broken, the fragments will be stuck to the film, and the broken glass surface will remain clean and smooth.
Compared with other glass, it has the properties of shock resistance, anti-theft, bullet proof and explosion-proof, which can effectively prevent the occurrence of fragment stabbing and penetrating falling, and ensure personal safety.
6. What is Low-E glass?
Low-E glass, also known as Low radiation glass, is coated with a layer of film on the surface of the glass to block the ultraviolet radiation. The coating layer has the characteristics of high transmittance to visible light and high reflection to middle and far infrared rays. Compared with ordinary glass and traditional coated glass for buildings, Low-E glass has excellent heat insulation effect, good transmittance and good anti ultraviolet function.
7. What are the advantages and disadvantages of offline Low-E and online Low-E?
On line Low-E glass: it can be used in a single piece, can be glued, can be bent steel, and its price is cheaper than offline, but the color is single, only two colors of high permeability and blue gray, single glass has poor thermal insulation performance.
Off line Low-E glass: it is composed of four or more layers of films, with various varieties. According to different climatic characteristics, it can make products with high, medium and low transmittance. The colors are silver gray, light gray, light blue, colorless and transparent, etc.
Product adaptability: in oversea, online Low-E glass is mainly used in Low-Rise civil buildings. Off line Low-E glass is mainly made of toughened insulating glass, which is used in high-grade buildings such as commercial buildings.
8. What is hollow louver glass?
It is to install metal aluminum sheet inside the insulating glass, which is controlled by magnetic force. The angle can be adjusted freely to make it fully transparent, semi transparent or shading. At the same time, it can pull up all the shutters and turn them into all transparent windows. It can be used 20000 times for about 20 years. The product not only saves space, but also achieves the purpose of sunshade. It also has the function of heat preservation and noise prevention. It is clean, hygienic and does not need cleaning. At the same time, it can bring novel visual effect.
9. Different types and characteristics of aluminum alloy doors and windows
Aluminum alloy doors and windows are mainly push-pull windows, casement windows, hanging windows, internal opening, inverted windows, fixed windows.
Sliding doors and windows: two doors and windows in the same plane, the fan can push and pull horizontally to the left and right.
Flat door and window: it is a door and window that is opened forward or backward. If the door and window are not in the same plane, it will occupy a certain space and open to the indoor or outdoor in the wall.
Upper suspended window: the upper end is fixed, the opening fan is inclined to open, and the opening is below.
Internal opening and internal inverted window: the European standard is adopted. It can be opened indoors for natural ventilation. Doors and windows can also be opened when people are not at home. No matter how long a high-rise building is used, you don’t have to worry about hitting the downstairs.
Fixed doors and windows: doors and windows that cannot be opened.
10. What are system doors and windows?
System doors and windows originated in Europe, through years of use, in the design of doors and windows to consider the airtight and energy-saving effect. System doors and windows are integrated door and window system solutions adopted by the system company to make a clear commitment to the performance and quality indicators of products. A series of important functions, such as water tightness, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, anti-theft, sunshade, weather resistance, operation feel, etc., should be considered, as well as equipment, profiles, accessories, glass, glue, and sealing piece
11. What is the thickness standard of aluminum alloy door and window profile?
The wall thickness of the main stressed parts of aluminum alloy window profile is not less than 1.4mm, and when the high-rise building reaches more than 20 floors, the thickness of profile can be increased; the wall thickness of the main stressed part of heavy-duty sliding door profile is not less than 2.0mm; this is the national standard, which meets the requirements of wind pressure resistance. Single door and window can be thickened if it is more than 3-4 square meters, and columns can be added if it is too large to increase its physical strength.
12. What are the main hardware accessories of aluminum alloy doors and windows?
Main hardware accessories of casement window: linkage handle, sliding brace, hinge, lock point, lock box, back buckle lock, heaven and earth lock, etc;
The main hardware accessories of inner opening and inner inverted window: linkage handle, connecting rod, linkage, etc.
13. What is the difference between hot bending and bending tempering?
The hot bending glass is formed by heating the glass to the softening temperature, then bending and forming by self weight or external force and natural cooling; the bending toughened glass is made by rapid air cooling with special equipment after bending forming. The hot bending glass does not belong to the safety glass, while the bent steel glass belongs to the safety glass.
14. Characteristics of tempered glass and semi tempered glass
The strength of tempered glass is 4-5 times of that of ordinary glass, and it becomes small particles after being broken, which belongs to safety glass; it can withstand the temperature mutation of 250-320 degrees, with the disadvantages of self-explosion, unable to cut and reduced flatness after tempering. The strength of semi tempered glass is between ordinary glass and tempered glass, which is not easy to self-explode and has good flatness, but its heat resistance and impact resistance are inferior to that of tempered glass.
15. How to identify high quality aluminum alloy doors and windows?
When buying doors and windows, try to choose products with good market reputation and perfect after-sales system.
