PVC plastic doors and windows is a new type of building material. It is more corrosion-resistant than wooden windows and steel windows, and does not require paint maintenance. Compared with aluminum alloy windows and steel windows, it has better thermal insulation, sound insulation and sealing performance, and has a colorful appearance. It can be coordinated with all kinds of buildings.

What are pvc plastic doors and windows Introduction to the advantages and disadvantages of plastic doors and windows

In recent years, the production and application of plastic doors and windows has developed rapidly and has become one of the leading products in the door and window market. PVC plastic doors and windows are a new type of building material. It is more corrosion-resistant than wooden windows and steel windows, and does not require paint maintenance. So, what are pvc plastic doors and windows? Is it durable? , Next, let’s learn more about the relevant knowledge of plastic doors and windows with Xiaobian, as well as the advantages and disadvantages of plastic doors and windows.

First, what is pvc plastic doors and windows

PVC plastic doors and windows are the most common kind of doors and windows, which are affordable, durable and not easy to deform. Polyvinyl chloride plastic doors and windows are made of polyvinyl chloride (PVC) resin as the main raw material, adding a certain proportion of stabilizers, modifiers, fillers, UV absorbers and other auxiliary formulations and modifications, and extruded through an extruder. Hollow profiles formed into various fault structures are cut to length, lined with steel profile reinforcing ribs, and then welded into door and window frames and fans with a hot melt welding machine, and assembled with sealing strips and brush strips. , glass, hardware accessories, etc. constitute the finished doors and windows. In order to increase the rigidity of the PVC plastic hollow profile, the inner cavity is lined with human-shaped steel to strengthen it to form a plastic-steel structure, so it is also called a plastic-steel door and window.

PVC is the English abbreviation of polyvinyl chloride: "RPVC" or "UPVC" before "plastic doors and windows" is actually the same material, namely "rigid polyvinyl chloride" or "unplasticized polyvinyl chloride".

PVC plastic doors and windows is a new type of building material. It is more corrosion-resistant than wooden windows and steel windows, and does not require paint maintenance. Compared with aluminum alloy windows and steel windows, it has better thermal insulation, sound insulation and sealing performance, and has a colorful appearance. It can be coordinated with all kinds of buildings.

Second, the advantages of plastic doors and windows

1. Anti-corrosion, acid, alkali, salt, etc., it will not corrode, mildew and moth-eaten in humidity, salt spray and acid rain.

2. The shape and size are stable, not loose or deformed.

3, long life, can be used normally for about 30 years.

4. It is self-flammable, does not burn, has self-extinguishing property, and has a high oxygen index of more than 40, which is conducive to fire prevention. Since the oxygen content in the air is about 20%, plastic windows will not burn in natural environment.

5. Beautiful appearance, strong texture, rich colors, easy to scrub and clean.

6. It is light and flexible to use, resistant to impact, and there is no impact sound when switching. This is mainly because the sealing materials of doors and windows are elastic materials such as PVC and EPDM.

7. Basically no maintenance, no paint is required, and the use cost is low.

8. Air tightness and water tightness are much better than steel and wooden doors and windows, which are generally 2-3 grades higher than them. Airtightness and watertightness can cause many problems, such as energy loss due to heat exchange between indoor and outdoor.

Third, the disadvantages of plastic doors and windows

Since the elastic modulus of the PVC material is low, only about 1/80 of that of steel, in order to achieve the material rigidity required for the wind resistance of the window, we increase the material section, increase its moment of inertia, and add in the appropriate cavity. Steel lining.

Due to the generally large cross-section of the material, the light-blocking area of ​​the material increases, resulting in the square area of ​​the entire window being about 5%-11% smaller than that of the steel window, and about 4%-9% smaller than that of aluminum.

Due to the increase of the material section, the corresponding material line weight also increases, resulting in a higher cost of the window, which is 30%-50% more expensive than the steel window when installing single glass, but in some cold areas, PVC with single-layer double glass is installed. Compared with the double-speed single-glass aluminum alloy window, the cost of the window is lower than the latter, but the PVC window is much better than the double-speed aluminum alloy window for heat preservation and lighting. This is also one of the most successful reasons why PVC windows are popularized in the cold regions of our country.
