1, thermal insulation

Referring to insulation performance, we need to compare the basic technical parameters of the material. For example, the thermal conductivity of PVC material is 0.14, while that of aluminum alloy is 175. In other words, under the same conditions, in terms of material thermal conductivity, aluminum is 1250 times that of PVC. Of course, if PVC is made into doors and windows, it is difficult to generalize the comparison of energy consumption. Because of the loss of heat in the room, it is usually related to roofs, floors, walls and doors and windows. However, scientific research shows that as an ordinary residence, air conditioning is also turned on, and rooms with plastic steel doors and windows have more than 5 degrees of electricity per day than rooms equipped with aluminum alloy doors and windows.

2, sound insulation performance According to data show that plastic doors and windows of the sound insulation performance is much better than aluminum alloy doors and windows.

For example, for a building that meets the same noise requirements, the distance between the building that installs aluminum alloy doors and windows and the main roads for traffic needs to be 50 meters away, and if it uses steel doors and windows, it can be shortened to within 16 meters.

3, product style and process performance

Plastic steel doors and windows and aluminum alloy doors and windows can be made into flat open, push and pull, hanging and curved windows according to the design requirements of the designers. Plastic steel door and window surface can be colored, covered, multi-color co-extruded; aluminum alloy doors and windows can be sprayed on the surface, electrophoresis, color can also be diversified.

4. Installation performance and service life of doors and windows

Plastic steel doors and windows are significantly lower than aluminum alloy doors and windows, but also due to the overall molding, installation speed is very fast, which makes the entire ergonomics greatly improved. In terms of service life, the normal service life of steel doors and windows is 30 to 50 years, which is lower than aluminum alloy doors and windows.

5, corrosion resistance

Plastic steel doors and windows can resist acid and alkali corrosion and other chemical substances, so they are not afraid of urban environmental pollution, hydrochloric acid and acid rain and other erosion. The aluminum alloy is not so easy to cause surface oxidation and shorten the service life.
