The performance of upvc doors and windows

The performance of upvc doors and windows

Oct 18, 2022

Plastic steel doors and windows are made of polyvinyl chloride (UPVC) resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc.
Door and window sashes are made by cutting, welding or screwing.
It is equipped with sealing strips, wool strips, hardware, etc., and at the same time to enhance the rigidity of the profile, the cavity of the profile exceeding a certain length needs to be filled with steel lining (reinforcing ribs).
It is called plastic steel doors and windows.

Insulation and energy saving:


The plastic-steel doors and windows are multi-chamber structures with good thermal insulation performance, and their heat transfer performance is very small, only 1/357 of that of steel and 1/250 of that of aluminum. It can be seen that plastic doors and windows have significant thermal insulation and thermal insulation effects, especially
It is more suitable for modern buildings with heating and air conditioning equipment.
Investigation and comparison, that is: the indoor temperature of the room using plastic steel doors and windows can be 4-5 degrees higher than that of wooden doors and windows in winter; the effect of using double-layer glass in northern areas is better. According to the test of the Institute of Physics of the Construction Research Institute, The heat transfer coefficient of single glass fiber reinforced plastic and aluminum windows is 64W/M2K; the heat transfer coefficient of single-glass plastic-steel windows is about 47W/M2K; the heat transfer coefficient of ordinary double-glazed steel and aluminum windows is about 3.7W/M2K;
The heat transfer coefficient of double glass plastic steel windows is about 2.5W/M2K. Doors and windows account for 30% of the building's outer protective structure area, 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), rainwater leakage (water tightness), wind pressure resistance and thermal insulation and sound insulation performance of PVC plastic steel doors and windows. Due to plastic steel doors and windows profile has a unique multi-chamber structure, and is welded into doors and windows. When the plastic steel doors and windows are installed, all the gaps 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, hardware is metal products, and has corrosion resistance.
Industries in corrosive environments, such as food, medicine, sanitation, chemical industry and coastal areas, rainy and humid areas, choose anti-corrosion hardware (engineering plastics),Its service life is 10 times that of plastic steel doors and windows.
 

Weather resistance:


The plastic-steel doors and windows adopt a special formula, adding ultraviolet absorbers and low-temperature impact agents to the raw materials, thereby improving the weather resistance of the plastic-steel doors and windows. Long-term use in a temperature climate environment, a
Between 30 degrees and 70 degrees, there is no discoloration, deterioration, aging, embrittlement and other phenomena in the changes of hot sun, heavy rain, dryness and humidity. Plastic steel windows have been used in Western Europe for 30 years, and their materials are as good as ever.
 

Fire resistance:


Plastic-steel doors and windows are non-spontaneous, non-combustible, self-extinguishing away from fire, safe and reliable, and meet fire protection requirements. This performance further expands the use of plastic-steel doors and windows.
 

Insulation properties:


Plastic steel doors and windows use excellent electrical insulators with special profiles, which are non-conductive and have a high safety factor.
 

Air tightness:


The quality of plastic steel doors and windows is fine and smooth, and the quality is consistent inside and outside. No special surface treatment is required. It is easy to process. After cutting and welding, the length, width and diagonal of the finished doors and windows can be within plus or minus 2MM. The machining accuracy and angular strength can be Up to 3000N or more.
 

Sound insulation performance:


It is mainly due to the sound insulation effect of glass that occupies about 80% of the area. Some sound insulation plastic steel door and window products on the market use different glass combination structures according to the resonance transmission principle of sound waves and the cooperation of lotus roots.
For example, insulating glass plastic steel windows, ordinary double-layer glass, enhance the sound insulation effect of doors and windows. In terms of door and window structure, the use of high-quality adhesive strips and plastic sealing accessories makes the sealing performance of plastic steel doors and windows remarkable.
