[China Aluminum Network] closed balcony has become an indispensable part of home decoration, taking into account the safety of the exclusion of the frameless window, leaving the more common is the aluminum alloy and plastic steel, then use the aluminum alloy when sealing the balcony Are some solid or plastic steel better? Here's a comparison for everyone to see, you will know after reading. 1, from the insulation performance Plastic steel doors and windows use plastic as the main material, and the material itself has a small thermal conductivity and relatively good thermal insulation performance. Aluminum alloy doors and windows due to the rapid thermal conductivity of metal materials, insulation performance is relatively poor. Generally in order to improve the insulation effect, some insulation strips will be added to achieve the effect of insulation. 2, from the durability Aluminum alloy material hardness than steel, sturdiness and durability. Although the steel material will be filled with steel to increase the hardness in the middle, it is easily damaged by heat and has a short service life. 3, from the sound effect The sound insulation effect is mainly affected by the sealing degree of the door and window glass and the overall door and window, and the sound insulation effect of both is almost the same. 4, from the safety performance Most houses are now high-rise buildings, and the higher the number of houses, the greater the impact of wind. The tensile strength and elasticity of plastic materials are inferior to those of aluminum alloys. From a safety point of view, high-rise tenants are still more reliable in selecting aluminum alloy materials, especially in places where there are multiple typhoons. 5, from the appearance of technology Affected by its own material, plastic doors and windows are mostly white, windy and easy to yellow, long time affect the appearance. The aluminum alloy material is a metal material, and the surface will be anti-corrosion treatment, there is almost no discoloration. To sum up, it is recommended to choose the aluminum alloy material when sealing the balcony. The appearance of the surface is hard and the service life is long. The more important is the safety performance! Linyi Hmbyan International Trading Co.,Ltd , https://www.hmbyandecor.com
