Aluminum alloy doors and windows are the connecting channel between each room and the outside world, so the installation quality of aluminum alloy doors and windows is particularly important. However, after the installation of aluminum alloy doors and windows, what points can owners refer to during acceptance to determine whether the installation meets the standard? 1. Use experience: ① Confirm whether the switch of aluminum alloy doors and windows is smooth, such as whether the switch of aluminum alloy doors and windows is smooth and whether the doors and windows will rebound or shake after locking. ② Then shake your hands back and forth to observe whether the stress of aluminum alloy doors and windows is normal, whether they are blocked or make a big noise. ③ Close the aluminum alloy doors and windows and check whether the fitting between the door leaf and the door frame is accurate and reasonable. Generally, the gap between the door leaf and the door frame should not exceed 2mm. 2. Door leaf frame inspection: The appearance inspection of aluminum alloy doors and windows includes whether there are cracks and deformation on the surface and the installation inspection of window rubber. The following are the specific operations of the inspection: ① Check the sealing strip: the contact between the sealing strip and the glass and the glass notch shall be flat without crimping and grooving. The pressure strip with sealing strip must be close to the glass. There shall be no obvious gap between the pressure strip and the profile, and the joint gap shall be less than or equal to 1mm. ② Check appearance: check whether the gloss and surface of aluminum alloy doors and windows are uneven, whether the surface is smooth, without depression and scratch, and then take a ruler to check whether the overall shape of aluminum alloy doors and windows is deformed. PS: the surface quality of aluminum alloy doors and windows directly affects the decoration effect of the whole wall after installation. Consumers are advised to check it strictly. 3. Door and window frame inspection: ① Check whether the joint between the door and window frame and the wall is tight. The edge of the door and window frame can be checked by the combination of reflector and expansion pipe. ② The installation of door and window frames directly affects the firmness of aluminum alloy doors and windows in later use, which can be checked from their firmness, flatness and tightness. ③ Check the perpendicularity range of door and window frames with a vertical measuring ruler. Generally, the allowable deviation of perpendicularity of front and side of aluminum alloy door and window frames is 2.5mm, the allowable deviation of horizontal frame is 2mm, the allowable deviation of elevation is 5mm, and the allowable deviation of vertical deviation from the center is 5mm. 4. Check the installation of door lock: ① First, check whether the installation position of door and window locks is correct and whether ...

The principle of heat insulation broken bridge aluminum interior doors and windows is to insert heat insulation strips into the aluminum profile base to disconnect the aluminum profile to form a broken bridge, which is useful to block heat conduction. The thermal conductivity of insulated aluminum alloy doors and windows is 40 ~ 70% lower than that of non insulated aluminum alloy doors and windows. Advantages of broken bridge aluminum: 1. Broken bridge aluminum fireproof function. Aluminum alloy is metal and will not be burned. 2. Broken bridge aluminum. Windproof sand and wind pressure resistance. The inner frame straight material adopts hollow planning, strong wind pressure deformation resistance and good sensation resistance. It can be used for high-rise construction and civil residence.

Aluminum door window are already essential decoration materials for house decoration in the current market, but in the face of many aluminum alloy doors and windows products in the market, consumers are also more hoodwinked. What skills do you have to learn about the purchase of aluminum alloy doors and windows with kdsbuilding today? 1. Process treatment of aluminum alloy doors and windows Check whether there are welding defects on the surface of aluminum alloy doors and windows, such as open welding, missing welding and other problems. Also carefully check whether the paint surface of the product is bright in color and clear in texture. Note that the paint surface shall not have obvious scratches, bubbles and other defects, whether the aluminum alloy doors and windows are closed tightly with the door frame, whether the gap is uniform and whether the switch is flexible. 2. Look at the thickness of aluminum door window Aluminum alloy door and window profiles used in general home decoration have various specifications such as 0.8mm, 1.0mm and 1.2mm. Among them, aluminum alloy doors and windows with a thickness of more than 1.0mm have better strength, and the thickness of profiles directly determines the quality of aluminum alloy doors. Good aluminum alloy doors and windows can remain undeformed within 10 years on the premise of normal use. Therefore, kdsbuilding suggests that when purchasing aluminum alloy doors and windows, consumers should not be greedy for cheap and choose aluminum alloy doors and windows with too thin profiles. 3. See the sealing performance of aluminum windows and doors When selecting glass surface materials for aluminum alloy doors and windows, it is recommended to select double-layer hollow tempered glass. In particular, pay attention to the sealing performance of the aluminum alloy door and window products you selected. Check the sealing performance of the glass partition of the aluminum alloy door and window, whether the glass adhesive coating on the front is tight, and whether the sealing strip on the back glass of the door is flat, without crimping and grooving.

Just look good? When purchasing aluminum door and windows, some people think it's OK to have a good appearance. However, if they ignore the details, it is very likely to lead to the "medium look and useless" of the installed doors and windows in the future. Therefore, when purchasing aluminum alloy doors and windows, we should pay more attention to details. Observe whether the protective film on the surface of doors and windows is obviously damaged and free of stains, the construction coloring of adjacent parts shall be free of obvious color difference, and there shall be no overflow adhesive on the connecting components. Hardware is not important? Sometimes there is an illusion: hardware accessories are very insignificant and have a low position in the materials used for aluminum alloy doors and windows. In fact, hardware accessories are the heart of doors and windows. The system built by hardware accessories determines the performance of doors and windows. Hardware parts are made of materials suitable for themselves according to their different parts and functions. The quality of pulley depends on its outer wheel and bearing. The thicker the profile, the better? Many consumers feel that the thicker the aluminum alloy door and window profile, the better the quality of the door and window when it exceeds the national standard. First of all, this concept is wrong, in fact, it is not so; Secondly, the wall thickness of profile has a great impact on the price. The national standard for wall thickness of aluminum alloy doors and windows is to ensure the safety and performance of doors and windows. Too thick profiles can not guarantee the performance of doors and windows, and will waste resources. The sign doesn't matter? When purchasing aluminum alloy doors and windows, it should be noted that generally regular manufacturers have production licenses, and there will be obvious product marks on the doors and windows. We need to check the product logo, identify the content of the logo, and ask them to show their production license and other certificates. So as to avoid impersonation and imitation of doors and windows and prevent being deceived.

Compared with single-layer glass, double-layer glass is more popular! I believe everyone will have an understanding of the glass structure when decorating balcony windows, such as single-layer glass and double-layer glass is the most common choice. Of course, compared with single-layer glass, double-layer glass is more popular! As for why? Let's learn more about it with me. Next, Xiaobian will talk about the difference between single-layer glass and double-layer glass. Single layer glass, as the name suggests, is only single-layer structure. The whole body adopts only one material, with moderate thickness and relatively general firmness. Thermal insulation is far less effective than double glass. If the single-layer glass is not pasted with glass film, once it is broken, the whole glass will be broken, and there are certain potential safety hazards. However, single-layer glass is still good in terms of cost performance and affordable price. For ordinary families, it is still the first choice for installation. Double layer glass is also called hollow glass. This kind of glass is composed of two layers of flat glass. The gap is usually filled with some high-density glue and then pasted with sealing strips. Some double glass will be filled with inert gas in the middle. Because of this structure, double-layer glass has good heat insulation, sound insulation and heat preservation. But the price of double-layer glass is not cheap. We should consider the decoration budget before choosing. What are the advantages of double glazing 1. Superior insulation Double layer glass is generally matched with aluminum-plastic composite materials. The combined thermal conductivity of the two is polar, and the thermal insulation effect is 1200 times higher than that of ordinary aluminum. Coupled with good air tightness, it can achieve the living effect of both outdoor and indoor worlds. 2. Good sound insulation The joints of double-layer glass are very tight. After being tested by authoritative institutions, the sound insulation effect reaches 30dB. In noisy metropolis, it can give you a quiet sleep. 3. Strong impact resistance The impact resistance of double-layer glass window is strong, and the surface material is aluminum alloy, which makes it stronger than ordinary plastic steel window. 4. Good anti-theft performance Double glazed windows are basically equipped with good hardware and high-grade locks. Thieves have to work hard if they want to break in and steal. The above is all about the difference between single-layer glass and double-layer glass and the advantages of double-layer glass windows. If your home has a sufficient decoration budget, double glass can be a good choice for you.

Glass has a wide range of applications and can be seen in many occasions. In terms of interior decoration, painted glass and hot-melt glass can be used, with changeable styles; Toughened glass, laminated glass and other safety glass are suitable for occasions where personal safety needs to be protected; When you need to adjust brightness and protect privacy, you might as well use frosted glass and dimming glass, which is convenient and durable. Want to know what are the common door and window glasses? KDS glass tells you! What are the common door and window glasses? KDS the glasses tells you! 1. Ordinary flat glass is also called window glass Ordinary flat glass has the properties of light transmission, heat insulation, sound insulation, wear resistance and climate change resistance, and some have the characteristics of heat preservation, heat absorption and radiation protection. Therefore, it is widely used in doors and windows, walls and interior decoration of inlaid buildings. 2. Tempered glass is also called strengthened glass Tempered glass is a kind of glass that is heated to a certain temperature and cooled rapidly, or specially treated by chemical methods. The characteristic of tempered glass is high strength. The bending strength and impact strength of tempered glass are 3 ~ 5 times higher than that of ordinary flat glass. 3. Hot bending glass Hot bending glass is a curved glass made by heating and softening flat glass, forming in a mold, and then annealing. Hot bending glass appears more and more frequently in some high-grade decoration. It needs to be reserved and there is no stock. 4. Wire glass is also called shatterproof glass The wire glass is made by heating the ordinary flat glass to the red heat softening state, and then pressing the preheated iron wire or wire mesh into the mid
