Home decoration is essential for the selection of doors and windows. Due to the sealing, air tightness, beauty, sound insulation, environmental protection and practicability, aluminum alloy doors and windows are loved by modern consumers. But most consumers do not know how to choose aluminum alloy doors and windows. After all, how to choose aluminum alloy windows to ensure sound insulation and energy saving?
Look at the thickness of aluminum alloy door and window profile
Aluminum alloy doors and windows have the characteristics of high strength, strong corrosion resistance, not easy to deform and more beautiful, so they are more and more loved and recognized by modern consumers. However, in the daily use of consumers, many consumers will find that the use of aluminum alloy doors and windows has not been in shape for a year. According to the inspection results of weatherability, thermal insulation and sound insulation of aluminum alloy door and window frames, it is confirmed that the aging process of rigid PVC is a very slow process. The service life of aluminum alloy doors and windows can reach about 50 years. Under normal operation, in addition to external force factors, aluminum alloy doors and windows show deformation in a short period of time, which may be caused by the thickness of profile used is too thin.
It is understood that the aluminum alloy doors and windows for consumers to choose and buy in the building materials shopping malls are usually 0.8 mm, 1.0 mm, 1.2 mm and other thicknesses. The aluminum alloy doors and windows with a thickness of more than 1.0 mm have higher strength, and can be used for 5-8 years without deformation under the premise of normal operation. However, there are also some small manufacturers in order to reduce production costs and improve income and choose to cut corners, and even use the thickness of only 0.6 mm aluminum alloy profiles. Because the thickness is not good, it is easy to deform by external force elements.
Guanhao doors and windows tips: aluminum alloy doors and windows profile thickness, will directly determine the quality of aluminum alloy doors and windows. In the purchase, do not greedy for temporary cheap, but to choose the wall thickness of qualified goods.
Look at the sealing strip of aluminum alloy doors and windows
Aluminum alloy doors and windows usually have a variety of art glass. These glass have a single layer, but also have a strong three-dimensional sense, good sound insulation effect of double tempered glass, which is not the same big, and is also an important factor in determining the quality of aluminum alloy door and window merchants.
When selecting aluminum alloy doors and windows with inlaid glass, especially the products planned by insulating glass, we must pay attention to its sealing function. If the sealing is not good, it will not only cause the hollow layer to hide dirt and dirt, affect the beauty, but also cause the sealing is not good, greatly affecting the energy saving and sound insulation of the room. The excellent imported sealant strip selected by Guanhao doors and windows products, with the leading hot pressing sealing technology, can effectively prevent dust and water, and the sound insulation and energy saving effect is more and more outstanding.
Tips: to check the sealing performance of the glass partition layer of aluminum alloy doors and windows, in addition to checking whether the glass glue coating on the front is tight, it is also necessary to check whether the sealing strip on the glass back of the door is flat, and there is no curling or sloughing.
See if there are obvious defects in technical welding
At present, with the continuous development of shopping malls, coupled with the relatively simple production technology of aluminum alloy doors and windows, many small manufacturers and even small workshops can produce, so the quality can not be guaranteed. Due to the concave and convex welding technology, the quality of aluminum alloy doors and windows will be directly reflected, which is also the shortage of small manufacturers. Excellent aluminum alloy doors and windows, not only precision workmanship, welding elegant, so some of the splicing parts are very flat. However, for defective aluminum alloy doors and windows, blind selection of aluminum profile series and specifications, cutting corners and other directions of the door frame can not be flat, sometimes even presents a large gap.
