Doors and Windows are an important part of the building maintenance structure. Doors and Windows of residential installations are usually divided into wood doors and Windows, iron doors and Windows, aluminum alloy doors and Windows, plastic steel doors and Windows, among which the most advanced ones are plastic steel doors and Windows. Plastic steel doors and Windows are new energy-saving building doors and Windows that have just been developed. The use of plastic steel doors and Windows, indoor heat outflow loss is much less than other information doors and Windows, energy saving and insulation effect is very significant. Plastic steel doors and Windows are made of UPVC materials, lined with carbon steel keel, extruded, cut, welded, and made with hardware and rubber seals. It is named for its carbon steel keel lining. Plastic steel doors and Windows not only integrate the advantages of the previous several doors and Windows, but also superior. Plastic steel doors and Windows are light and clean, flexible opening, simple and generous appearance, anti-aging, high-quality plastic steel doors and Windows can be more than 30 years of life. In addition, plastic steel doors and Windows also have flame retardant, high strength, super sealing characteristics.

Thermal insulation and energy saving performance of plastic steel doors and Windows

Plastic steel doors and Windows are multi-cavity structure, with good heat insulation performance, and its heat transfer performance is very small. Only l 357 aluminum 1 250 steel can see that plastic doors and Windows have remarkable heat insulation and heat preservation effect, especially for modern buildings with heating and air conditioning equipment. Relevant departments have carried on this

Investigation comparison, that is: the use of plastic steel doors and Windows than the use of wood doors and Windows of the room in winter indoor temperature can be 4 and 5 degrees higher; Double glazing is better in the south. According to the test of the Institute of Physics, 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 glass steel and aluminum window is about 37W /M2K. The heat transfer coefficient of double-glass plastic steel Windows is about 25 W/M2K doors and Windows, accounting for 30% of the building outer protective structure area, and the heat dissipation accounts for 49%. Therefore, the plastic steel Windows have good energy saving benefits.

Physical properties of plastic steel doors and Windows

The physical properties of plastic steel doors and Windows mainly refer to the air permeability (air tightness) of PVC plastic steel doors and Windows, rain permeability (water tightness), wind resistance and insulation and sound insulation performance. Because the plastic steel door and window profiles have a unique chamber structure, and the doors and Windows are made by welding process, all the gaps of plastic steel doors and Windows are equipped with sealing rubber strips and wool strips when the doors and Windows are installed, so it has good physical properties.

Corrosion resistance of plastic steel doors and Windows

Plastic steel doors and Windows have good corrosion resistance because of their unique formula. Secondly, the corrosion resistance of plastic steel Windows depends on the use of hardware. Under normal circumstances, hardware is metal products, and industries under corrosive environment, such as food, medicine, health, chemical and coastal areas, rainy and humid areas, The selection of anti-corrosion hardware (engineering plastic) is 10 times the service life of plastic steel doors and Windows.

Weatherability of plastic steel doors and Windows

Plastic steel doors and Windows with special formula, raw materials add ultraviolet absorbent, and low temperature impact resistant agent, thus improving the weather resistance of plastic steel doors and Windows. Temporarily used in the environment of temperature climate, between 30 degrees to 70 degrees, the sun, rain, dry, wet changes, no discoloration, disintegration, aging, embrittlement and other phenomena. Plastic steel Windows have been used in Western Europe for 30 years, and the material is as good as before.

Fire resistance of plastic steel doors and Windows

Plastic steel doors and Windows are not spontaneous combustion, non-combustion, fire self-extinguishing, safe and reliable, in line with the requirements of fire prevention, this performance expands the scope of use of plastic steel doors and Windows.

Insulation properties of plastic steel doors and Windows

Plastic steel doors and Windows use profiles of excellent electrical insulation, non-conductive, high safety factor.

Plastic steel doors and Windows are air tight

The quality of plastic steel doors and Windows is fine and smooth, the quality is consistent inside and outside, without the appearance of special disposal, easy processing, after cutting, welding processing, the length, width and diagonal of doors and Windows waste can be within 2MM, processing accuracy, Angle strength can reach more than 3000N.

Sound insulation performance of plastic steel doors and Windows

It mainly lies in the sound insulation effect of glass, which accounts for about 80% of the area. Some sound insulation plastic steel doors and Windows on the market cooperate with lotus root according to the resonance transmission principle of sound wave, and adopt different glass combination structures, such as insulating glass plastic steel Windows and ordinary double glass, to enhance the sound insulation effect of doors and Windows. In terms of doors and Windows structure, the use of high quality rubber strips and plastic sealing accessories makes the sealing performance of plastic steel doors and Windows remarkable.

Plastic steel doors and Windows look good

Can and domestic decorative effect requirements to adapt, and human body contact feeling more comfortable than metal. Because of the above outstanding advantages of plastic steel doors and Windows, the country is being widely used, become a new trend in the field of architecture
