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.
Lu: su aluminum composite profiles: energy-saving door window a new generation of substitute
In today’s increasingly the serious situation of the energy shortage, production the energy conservation, the environmental protection product has become the development direction of all walks of life. Statistics show that our country building energy consumption have accounted for 40% of the total energy consumption of the whole society, the energy conservation of the building has caused the government and the society to the universal attention. The energy conservation of the building is refers to save heating heating, air conditioning and refrigeration, building lighting energy consumption. Development energy-saving building, form healthy civilization, save resources consumption model has the delay.
According to one of the chief discloses door, door window is building outside one of the opening of the structure parts, the construction of the eye, it in the building and the environment, indoor and outdoor is communication and separation of multiple and practical function. Our doors and Windows products performance is poor, the energy consumption per unit area for the developed countries of the 2 ~ 3 times, and the function of the doors and Windows quality, to habitant health, comfortable life and job conditions, has had a significant impact.
According to information, doors and Windows, of the total energy consumption of more than 50%. Thus, improving window of door of energy conservation, became the theme of building energy saving. What, then, Windows and doors profiles to make already energy-saving and excellent function, accord with the social development direction of the doors and Windows?
Long ago in aluminum alloy material made doors and Windows and curtain wall has become the first choice of materials, along with the development of the modern industry aluminum alloy, aluminum alloy doors and Windows and start building structure as curtain wall system is widely used material, and along with the application level of thorough, the people understand the aluminum alloy material, and willing to accept.
Due to the wood lift and sliding door light weight, beautiful, corrosion resistance, processing simple was the favour of people, but because of its heat insulation performance is bad, energy saving effect is poor, heat insulation performance is good, good energy saving effect of model steel profile have replaced the traditional aluminum alloy extrusion profiles lost his brilliance. Give full play to the model steel profile good effect of energy saving and aluminum alloy extrusion profiles of light weight, beautiful, corrosion resistance, processing the advantages of simple compound aluminum alloy extrusion profiles, is making already energy-saving and excellent function, accord with the social development direction of the doors and Windows of a new type of door window materials.
Recently in domestic sadly arisen, cause real estate developers, construction units, doors, Windows, manufacturers and the news media attention is the fifth generation said the lu: su aluminum composite new energy-saving doors and Windows, doors and Windows is a new generation of alternative product. Its excellent stays, wind pressure sex, sound insulation sex, water tightness, air tightness, reached national standards of A1 window.
The fifth generation of the new energy-saving Windows and doors profiles-new lu: su doors and Windows aluminum composite for both sides is outside aluminium alloy profile, heat insulation body modification is among more than PVC cavity. Its advantage is both aluminum alloy high strength, light weight, beautiful, corrosion resistance, processing is simple, and the characteristics of the model steel profile heat insulation, heat insulation energy-saving effect is very good.
