Abstract: uPVC windows is one of the common types of building doors and windows, so how about uPVC windows? The characteristics and advantages of uPVC windows are simple, beautiful, large window width, large glass blocks, wide field of view, high lighting rate, convenient glass cleaning, flexible use, safety and reliability, long service life, open in one plane, and occupy less space. It is convenient to install the screen window, etc. Moreover, compared with aluminum windows, wooden windows, and steel windows that achieve the same performance, Huge of uPVC windows is more economical and affordable, and is an ideal and reliable building door and window.

What are the characteristics of uPVC windows?

uPVC windows is made of hard polyvinyl chloride (PVC) resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc., extruded into profiles, and then cut, welded or screwed. The frame is made in the same way, and finally it is equipped with sealing strips, tops, hardware, etc. At the same time, in order to enhance the rigidity of the profile, steel lining (reinforcing rib) needs to be added in the cavity of the profile.

uPVC profiles are generally used for door and window frames, and doors and windows made of uPVC profiles are also called uPVC windows. uPVC windows have good air tightness, water tightness, wind pressure resistance, sound insulation and fire resistance, and the finished product has the characteristics of high dimensional accuracy, no deformation, and easy maintenance.

Advantages of uPVC windows

1. uPVC windows have good thermal insulation: the plastic in the aluminum-plastic composite profile has a low thermal conductivity, and the heat insulation effect is 1250 times better than that of aluminum. In addition, it has good air tightness. But it is another world.

2. uPVC windows have good sound insulation: the structure is carefully designed and the joints are tight. According to the test results, the sound insulation is 30db, which meets the relevant standards.

3. Impact resistance of uPVC windows: Since the outer surface of the aluminum-plastic composite profile is aluminum alloy, it is much stronger than the impact resistance of uPVC profiles window profiles.

4. Good air-tightness: Multiple sealing wool strips or rubber strips are installed in each gap of the aluminum-plastic composite window. The air-tightness is first-class, which can give full play to the air-conditioning effect and save 50% of energy.

5. Good water tightness: the doors and windows are designed with rain-proof structure, which can completely isolate the rainwater from the outside, and the water-tightness meets the relevant national standards.

6. uPVC windows have good fire resistance: uPVC windows are made of UPVC material, which does not spontaneously ignite or support combustion.

7. Good anti-theft performance: aluminum-plastic composite window, equipped with high-quality hardware accessories and high-grade decorative locks, making thieves helpless

8. Maintenance-free: Aluminum-plastic composite profiles are not easily corroded by acid and alkali, will not turn yellow and fade, and require almost no maintenance. When it is dirty, it can be scrubbed with water and detergent, and it will be as clean as ever after cleaning.

9. The best design: Aluminum-plastic composite windows are scientifically designed and use reasonable energy-saving profiles, so they are recognized and praised by the national authority and can add luster to the building.

Disadvantages of uPVC windows

1. The rigidity of PVC material is not good, and steel bars must be added inside to increase the hardness.

2. The fire performance is slightly poor. If the fire protection requirements are relatively high, it is recommended to use aluminum alloy materials.

3. The material of uPVC profiles is brittle, heavier than aluminum alloy, and will emit toxic emissions when burned.
