Insulation and energy saving
Plastic steel doors and windows are multi-cavity structure, with good thermal insulation performance, and its heat transfer performance is very small, only 1/357 of steel, 1/250 of aluminum, visible plastic door and window insulation, insulation effect is remarkable, especially for heating Modern buildings with air conditioning equipment are more suitable. Relevant departments have investigated this comparison, that is, the use of plastic steel doors and windows can be 4-5 degrees higher in winter than in rooms with wooden doors and windows; the use of double glazing in the northern region is better. According to the Institute of Physics of the Institute, the heat transfer coefficient of single glass steel and aluminum window is 64W/M2K; the heat transfer coefficient of single glass plastic steel window is about 47W/M2K; the heat transfer coefficient of ordinary double glazing steel and aluminum window It is about 3. 7W/M2K; and the heat transfer coefficient of double glass plastic steel window is about 2. 5W/M2K. Doors and windows account for 30% of the building's outer protective structure, and its heat dissipation accounts for 49%. It can be seen that plastic steel windows have good energy-saving benefits.
Physical properties
The physical properties of plastic steel doors and windows mainly refer to: air permeability (air tightness) of PVC plastic steel doors and windows, rain leakage (water tightness), wind pressure resistance and protection
Mild sound insulation of steel doors and windows. Because the plastic steel door and window profiles have a unique multi-chamber structure and are welded and formed into doors and windows, all the gaps in the steel-plastic doors and windows are equipped with door and window sealing strips and tops, so they have good physical properties.
Corrosion resistance
Plastic steel doors and windows have good corrosion resistance due to their unique formula. Secondly, the corrosion resistance of plastic steel windows depends on the use of hardware. Under normal circumstances, the hardware is metal products, and the industries under corrosive environment, such as food, In medicine, sanitation, chemical industry and coastal areas, wet and humid areas, anti-corrosion hardware (Engineering Plastics) is used, which is 10 times longer than plastic steel doors and windows.
Weather resistance
Plastic steel doors and windows adopt special formula, adding UV absorber and low temperature impact agent to the raw materials, thus improving the weather resistance of plastic steel doors and windows. Long-term use in temperature and climate environment, between 30 degrees and 70 degrees, in the sun, rain, dry, moisture changes, no discoloration, deterioration, aging, embrittlement and so on. Plastic steel windows have been in Western Europe for 30 years, and their materials are as good as ever.
Fire resistance
Plastic steel doors and windows are not self-igniting, do not support combustion, self-extinguishing from fire, safe and reliable, in line with fire protection requirements, this performance has expanded the use of plastic steel doors and windows.
Insulation performance
Plastic steel doors and windows use excellent electrical insulation of profiled materials, non-conductive and high safety factor.
Air tightness
The steel door and window are fine and smooth, the quality is uniform inside and outside, no special surface treatment, easy processing, cutting and welding, the length, width and diagonal of the finished door and window can be within plus or minus 2MM, processing precision, angular strength can be Up to 3000N.
Sound insulation performance
The main reason lies in the sound insulation effect of glass which accounts for about 80% of the area. Some soundproof plastic steel doors and windows on the market cooperate according to the principle of resonance and transmission of sound waves, and adopt different glass composite structures, such as hollow glass plastic steel windows and ordinary double glazing. Enhance the sound insulation of doors and windows. In the aspect of door and window structure, the use of high-quality rubber strips and plastic sealing fittings makes the sealing effect of plastic steel doors and windows remarkable.
Good appearance
It can be adapted to the domestic decorative effect requirements, and the human body feels more comfortable than metal. Due to the above-mentioned outstanding advantages of plastic steel doors and windows, it is getting a lot of applications in China and has become a new trend in the construction field.
More benefits
Doors and windows are an important part of the building maintenance structure. The doors and windows installed in residential buildings are usually divided into four types: wooden doors and windows, iron doors and windows, aluminum alloy doors and windows, and plastic steel doors and windows. The most advanced ones are plastic steel doors and windows. Plastic steel doors and windows are newly developed energy-saving building doors and windows. With plastic steel doors and windows, the indoor heat outflow loss is much less than that of other materials, and the energy saving effect is very significant. The plastic steel doors and windows are made of UPVC material, lined with carbon steel keel, extruded, cut, welded, and made of hardware and rubber seals. Because it is lined with carbon steel keel, it is named. Plastic steel doors and windows not only combine the advantages of the previous doors and windows, but also better. Plastic steel doors and windows are light and clean, flexible to open, simple and elegant in appearance, anti-aging, and the quality of plastic steel doors and windows can last for more than 30 years. In addition, plastic steel doors and windows also have the characteristics of flame retardant, high strength and super strong seal. The user can identify the quality of plastic steel doors and windows.
U-PVC plastic steel doors and windows is a new type of chemical building materials. It is the fourth generation of energy-saving doors and windows after wooden doors and windows, steel doors and windows, aluminum doors and windows. It is a high-quality energy-saving product recommended by the Ministry of Construction. Plastic steel doors and windows are made by cutting plastic profiles, welding them with reinforced steel, and then attaching seals, tops, hardware and other accessories.
Because of its beautiful appearance, strong corrosion resistance, water tightness and heat insulation, and easy maintenance, it is more and more popular.
