Model steel and aluminum alloy doors and Windows performance according to the energy saving
Plastic doors and Windows in the promotion use relative development is faster, especially in recent years, popularize the stepped up, many people just pay attention to plastic material itself thermal insulating properties, processing convenience and ignored it exists in the weak. The test shows that the elastic plastic window touch quantity was small, only 1/36 of the aluminum alloy material; Tensile strength of aluminum alloy material is 1/2, hardware accessories such as relatively weak installed nodes, these questions are all need to take seriously.
According to a city of 524 batch of plastic samples in detecting window statistical data show that: plastic window of wind of performance to the national level standard bengkaichuang accounted for 36.3%, push-pull window accounted for 6.3%, the window of rain penetration national level standard of performance to make the same score a window and push-pull window are 0. Can be applied to 21 to 25 layer above floor flat to open type window accounted for 73.6%, push-pull type window just 2.18%. Can be applied to 31 layer above flat to open type window 22.84%, push-pull type window for 0. These test results also is the sample of the censorship window. In addition, plastic window internal line steel chamber should be seal chamber, should guarantee cavity not damp, and if you can’t guarantee steel lining not damp, rust, it is hard to avoid. If the stress of corrosion and steel lining component failure, so the consequence is unimaginable.
Experts have stressed that in the present products and production unit technology guarantee condition, high wind pressure area of the high-rise building should be careful with plastic window, and to deal with window type specification to be strict control, for important hardware accessories must use the special lining board conjunction, of all kinds of plastic doors and Windows to the safe use of strict examination measures, in case the edge.
In our country’s energy saving doors and Windows on the market, and a large mainstream Windows and doors is energy-saving aluminum windows. This kind of door window through the broken bridge overcome the aluminum heat insulation as well as fast heat conduction weakness, and for the vast number of consumers to accept.
The relative investigation, aluminum alloy doors and Windows broken bridge type heat insulation performance is better than the actual application of the energy-saving door window of model steel.
In the building with window, aluminium alloy is energy-saving door window is also used in the high-end and building, and the price is higher.
In addition, from the point of view of environmental protection consideration, window of model steel door also exist recovery more difficult situation, such as plastic doors and Windows can neither burned, and should not be buried, and plastic window will emit poisonous in sawing smoke, emits poisonous gas fire "dioxin", to not environmental protection products.
