Advantages of PVC doors and windows

I, what is a PVC door and window

Plastic steel doors and windows are PVC resin as the primary steel, plus a certain proportion Stabilizer, colorant, filler, ultraviolet absorbers, etc., after extrusion molding, Then The door and window frame fan is made by cutting, welding or screws with sealant strips Hair ool, hardware, etc., to enhance the rigidity of the profile, over a certain length The cavity needs to be filled with a steel lining (reinforcement), through which the doors and windows are called plastic Steel doors and windows. At present, there are many kinds of plastic steel doors and Windows, according to the way of opening: open window, open door. Push and pull window, sliding door, fixed window, rotary window, etc. Classification by structure: single glass, double glass doors and Windows. By color: monochrome (white or color), two-color (co-squeeze, refilm, or spray).

II. Performance and characteristics of PVC doors and Windows


1. thermal insulation and energy saving
Plastic steel profile multi-cavity structure, with good heat insulation performance, very low heat transfer coefficient, only For 1 / 4.5 of steel lining and 1 / 8 of aluminum, its economic and social benefits are huge.
2. gas tightness
Plastic steel doors and windows are equipped with oak-plastic seals and strips at all gaps upon installation so Air tightness is much higher than the aluminum alloy doors and windows. And the air tightness of the plastic steel flat window is higher than the push and pull The tightness of the window, in general, the tightness of the window can reach four levels, push and pull the window Level 3.
3. water tightness
Because the plastic steel profile has a unique multi-cavity structure, all have independent drainage cavities, whether The water from the box or the fan can be effectively discharged. The water tightness of the plastic steel flat window is far higher than the push Pull the window, in general, the water tightness of the flat window can reach level 5, push and pull the window can be reached Level 3 to Level 4.
4. wind pressure resistance
In separate plastic steel cavity, 1.2-3mm thick steel lining locally. Wind pressure value, building height, hole size, window design to choose the reinforcement Thickness and profile series to ensure the building requirements of doors and windows. General high-rise buildings are optional Select a large section push window or inner flat window, wind pressure strength can reach more than 6 degrees, Low-floor building can choose a flat window or a small push-section window, the wind pressure strength is generally in three Level 10.
5. sound insulation
Plastic steel profile itself has good sound insulation effect, such as double glass structure More ideal, especially suitable for downtown places with serious noise interference, such as hospitals, schools, Hotels, office buildings, etc.
6. corrosion resistance
Plastic steel isoprofile has unique formula, good corrosion resistance, so plastic steel doors The corrosion resistance of the window mainly depends on the choice of hardware, such as choosing corrosion-resistant hardware, no Rust steel steel, its service life is about 10 times that of the steel window.
7. weather tolerance
Plastic steel special profile uses a unique formula to improve its cold resistance. Plastic steel doors and windows are long-term Use in large temperature difference (-50℃~70℃), no scorching sun exposure, humidity Will make it appear deterioration, aging, brittle and other phenomena, the earliest plastic steel doors and Windows have been used In 1930, its material was as good as before. According to this calculation, the plastic steel doors and Windows were used under normal conditions Life span for more than 50 years.
8. fire protection capability

Plastic steel doors and windows are not extinguished, non-combustible, self-extinguishing, safe and reliable, approved by Liaoning Province fire extinguishers The oxygen index tested by the Quality Supervision Station of Wood Products is 42.3, which conforms to GB8814-1988. The oxygen index specified in “U-PVC profiles for door and window frames” is not low. At the requirement of 38 degrees.

9. insulation
Plastic steel door window used in plastic steel profile for excellent electric insulation steel, not conductive, safe High coefficient.
10. finished product size accuracy is high, no deformation
Plastic steel profile with uniform lattice, clean surface, without special surface treatment, easy to process, Easy to cut, the length, width and diagonal tolerance of finished products can be controlled at 2mm. Within; high processing precision, welding angle strength above 3000N, and the welding site is cleared. Angle to remove the welding tumor, the surface of the profile welding site is smooth and beautiful.

11. easy to protect against it
Plastic steel doors and windows are not eroded, yellow and fade, free from ash, cement and adhesive shadow ring, almost no need to maintain, dirty, can use any cleaning agent, cleaning after white as before.
12. anti-theft nature
Plastic steel doors and Windows of the glass pressure bars are facing indoor, glass damage is easy to replace, plastic steel profile is strong High degree, high toughness, not easy to destroy, has a good anti-theft.
13. price: plastic compared to aluminum, wood and steel windows
The ge of steel doors and Windows is more affordable. Plastic steel doors and Windows have excellent physical generation properties, can be widely used in large wind, rain. High heat, alpine and corrosive gas and other harsh environmental places, are more ideal and reliable The building doors and Windows
