The closed balcony has become a part of the family decoration essential, considering safety so that eliminated frameless windows, the rest is the most commonly used Aluminum Alloy and steel, then seal the balcony with Aluminum Alloy be stronger or plastic is better? The following Xiaobian to compare to you, see you know.

　　1、See insulation performance

　　The use of plastic steel doors and windows as the main material, since the thermal conductivity of material, heat insulation performance is relatively good.

　　Aluminum alloy doors and windows due to rapid thermal conductivity of metal materials, heat insulation performance is poor. In order to improve the heat preservation effect, some heat insulation strips are added to achieve the effect of heat preservation.

　　2、Look from durability

　　Aluminum alloy material than plastic hardness, strong and durable. Plastic steel material although the middle will be filled with steel to increase hardness, but the heating is easy to aging and rupture, the service life is relatively short.

　　3、Look at the sound insulation effect

　　The effect of sound insulation is mainly affected by the tightness of doors and windows, glass and doors and windows, and the sound insulation effect of the two is almost the same.

　　4、Judging from safety performance

　　Now houses are mostly high-rise buildings, the higher the floor residents, the greater the impact of wind. The tensile strength and elasticity of plastic steel material are not comparable to those of aluminum alloy. From the safety considerations, the high level of household or aluminum alloy material more reliable, especially in the typhoon place is more attention.

　　5、Look from appearance and craft

　　Affected by the material itself, plastic material doors and windows are mostly white, exposed to the weather for a long time to affect the appearance of yellow. The aluminum alloy because of the metal material, and the surface will be anti-corrosion treatment, almost no discoloration.
       To sum up, sealing the balcony or choose aluminum alloy material, beautiful appearance, hardness and long service life, the most important thing is good safety performance!
