PVC Window Insulation and energy saving performance
Performance and characteristics of steel doors and windows
Insulation and energy saving performance of steel doors and windows
Plastic doors and windows for the multi-cavity structure, with good thermal insulation properties, its heat transfer performance is very small, only steel l / 357, aluminum 1/250, visible plastic doors and windows insulation, insulation effect is remarkable, especially for heating Modern buildings for air conditioning are more suitable. Relevant departments to investigate this comparison, namely: the use of steel doors and windows than the use of wooden doors and windows of the room temperature can be 4-5 degrees in winter; the use of double-sided glass in the north region better. According to the Institute of physical testing, single glass, aluminum window heat transfer coefficient of 64W / M2K; single glass steel window heat transfer coefficient is 47W / M2K or so; ordinary double glass of steel, aluminum window heat transfer coefficient Is about 3.7W / M2K; and double glass plastic steel window heat transfer coefficient of about 2.5W / M2K. Doors and windows accounted for 30% of the building area of the outer envelope, the heat accounted for 49%, which shows that plastic windows have a very good energy efficiency.
Plastic doors and windows physical performance
Plastic doors and windows of the physical properties mainly refers to: PVC plastic doors and windows of the air permeability (air tightness), rainwater permeability (watertight), wind resistance and insulation and sound insulation performance. As the steel doors and windows profiles have a unique multi-chamber structure, and the welding process from the doors and windows, steel doors and windows in the installation of all the gaps are equipped with doors and windows sealed strips and tops, and therefore have good physical properties.
Corrosion resistance of steel doors and windows
Plastic doors and windows because of its unique formula and has good corrosion resistance, followed by plastic steel window corrosion depends on the use of hardware, the normal environment of metal products for metal products, and corrosive environment of the industry, such as food, Medicine, health, chemical and coastal areas, rainy and humid areas, the choice of anti-corrosion hardware (engineering plastics), which is the life of plastic doors and windows is 10 times.
Plastic doors and windows weather resistance
Plastic doors and windows with special formula, the raw materials to add UV absorbers, and low temperature impact agent, thereby improving the steel doors and windows weather resistance. Long-term use in the temperature and climate of the environment, in a 30 degrees to 70 degrees, the sun, heavy rain, dry, wet changes, no discoloration, deterioration, aging, embrittlement and so on. Plastic windows in Western Europe has been 30 years of examples, the material intact as ever.
Plastic doors and windows fireproof
Plastic doors and windows are not spontaneous combustion, do not help combustion, from the fire self-extinguishing, safe and reliable, in line with fire protection requirements, this performance has expanded the use of plastic doors and windows.
Insulation performance of steel doors and windows
Plastic doors and windows use profile excellent electrical insulator, non-conductive, high safety factor.
Plastic doors and windows air tightness
The width, width and diagonal of the finished doors and windows are within 2MM of the positive and negative, the machining precision, the angle strength, the angle of the steel and so on. Up to more than 3000N.
Sound insulation performance of steel doors and windows
Mainly in the area of about 80% of the glass sound insulation effect, the market some sound insulation steel doors and windows products based on acoustic resonance transmission principle and lotus cooperation, the use of different glass composite structure, such as hollow glass plastic window, ordinary double glass, Enhance the doors and windows sound insulation effect. In the doors and windows structure, the use of high-quality plastic strips, the use of plastic sealing parts, making plastic doors and windows sealing performance effect is remarkable.
Plastic doors and windows look good
And the domestic decorative effect requirements to adapt, and the human body feel more comfortable than the metal. As the steel doors and windows have some outstanding advantages above, in our country is being a lot of applications, a new trend in the construction sector.
There are many benefits of steel doors and windows
