What are the main outstanding features of uPVC Profile?

uPVC Profile refers to PVC profiles used to make doors and windows. Because the strength of doors and windows processed by PVC profiles alone is not strong enough, steel is usually added in the cavity to enhance the firmness of doors and windows. Therefore, plastic doors and windows made of steel with steel inside the profile are usually called For plastic steel doors and windows. Then what are the main outstanding functions of uPVC Profile, introduced as follows:

      1. Thermal insulation and energy saving: uPVC Profile multi-cavity structure, with good thermal insulation performance, low heat transfer coefficient, only 1/357 of steel, 1/1250 of aluminum, its economic and social benefits are huge .

    2. Airtightness: all the gaps in the installation of plastic steel doors and windows are equipped with rubber and plastic sealing strips and tops, so the airtightness is much higher than that of aluminum alloy doors and windows. The airtightness of plastic steel casement doors and windows is higher than that of sliding windows. Air tightness. Under normal circumstances, the air tightness of casement windows can reach level five, and the air tightness of sliding windows can reach level two.

     3. Water tightness: Because the plastic steel profile has a unique multi-cavity structure, it has an independent drainage cavity, no matter the frame or fan, the water can be effectively discharged. The water tightness of the plastic steel casement window is much higher than that of the sliding window. Under normal circumstances, the water tightness of casement windows can reach level five, and sliding windows can reach level three to four.

    4. Wind pressure resistance: In the independent plastic cavity, 1.5~3MM thick steel lining can be filled, and plastic steel can be selected according to the local wind pressure value, the height of the building, the size of the opening, and the design of the window. Thickness and profile series to ensure the building's requirements for shaped doors and windows. High-rise buildings can choose large-section sliding windows or internal casement windows, and the wind pressure resistance can reach six levels or more. Low-rise buildings can choose external casement windows or small cross-section sliding windows. The wind pressure resistance of windows is generally at level 3.

     5. Corrosion resistance: uPVC Profile has a unique formula and good corrosion resistance. If anti-corrosion hardware and stainless steel profiles are selected, its service life is about 10 times that of steel windows.

     6. Weather resistance: uPVC Profile adopts a unique formula to improve its cold resistance. Plastic steel doors and windows can be used in environments with large temperature differences (-50℃~70℃) for a long time, and will not be deteriorated by sun exposure and humidity. , Aging, embrittlement and other phenomena, the earliest plastic-steel doors and windows have been used for 30 years, and their materials are as good as before. According to this calculation, the service life of plastic-steel doors and windows under normal conditions can reach more than 50 years.
