Compared with plastic steel doors and windows, we are no stranger, we can see the figure of plastic steel doors and windows in many places. Compared with the aluminum doors and windows, which kind of steel doors and windows will be better prepared? How about plastic steel doors and windows? Do you have the same question? So take a quick look at the following introduction, I believe we can give you a satisfactory answer to this question.

Plastic steel doors and windows and aluminum alloy doors and windows: air tightness

Because the frame and leaf components of plastic steel doors and windows are welded, the air tightness of plastic steel doors and windows should be slightly better than that of aluminum alloy doors and windows with screw connection. However, the dimension accuracy of heavy sliding door profile is higher, and the frame and leaf fit closely, so they are still at the same level.

Plastic steel doors and windows and aluminum alloy doors and windows: wind pressure strength and water tightness

Due to the low strength and rigidity of plastic steel doors and windows, the wind pressure resistance and water tightness of plastic steel doors and windows are about two grades lower than those of aluminum alloy doors and windows, although they are reinforced by lining rigidity. Because the lining steel of plastic steel doors and windows is not connected into a complete frame system in the inner cavity corner of its profile, the strength of plastic welding angle of window frame, four corners of fan and T-joint is relatively low.

Plastic steel doors and windows and aluminum alloy doors and windows: sound insulation performance

The sound insulation performance of heavy sliding door mainly lies in the sound insulation effect of glass which accounts for about 80% of the window area. "Aluminum alloy doors and windows" in the glass thickness, structure and sealing performance is good, so its sound insulation effect is very good.

Plastic steel doors and windows and aluminum alloy doors and windows: thermal insulation performance

Plastic steel window has the characteristics of heat preservation and heat insulation, which makes the room more comfortable, quiet and more modern. Moreover, the aluminum door and window frame profile is not solid, and the wall thickness of hollow aluminum profile is about 40% smaller than that of plastic profile.

Plastic steel doors and windows and aluminum alloy doors and windows: environmental performance

Compared with aluminum alloy doors and windows, plastic steel doors and windows have little recycling value, poor fire resistance and fast aging. Because they can't be degraded, they have less environmental protection performance than aluminum alloy doors and windows.

Therefore, the environmental protection performance of plastic steel doors and windows is slightly lower than that of aluminum alloy doors and windows, and the thermal insulation performance of plastic steel doors and windows is higher than that of general aluminum alloy doors and windows. How about plastic steel doors and windows? I believe you have found the answer in your heart.
