Decoration required course: buy plastic doors and windows Precautions - PVC, doors and windows, buy - Building Materials Industry

Plastic Doors and windows Is a new generation of door and window materials, because of high wind pressure, good airtight watertight, air, a small amount of rainwater infiltration, heat transfer coefficient is low, heat Energy , Noise insulation, the advantages of aging is not easy, is rapidly replacing steel windows, aluminum windows.

1, plastic doors and windows of the structure. Plastic doors and windows to special hard PVC Spanish (PVC) Plastic Profile-based materials, coupled with Hardware Pieces of composition. Profiles for the porous cavity, the main cavity with cold rolling Plate Liner made of steel, to increase the strength of plastic doors and windows. Profile of 2.5 mm wall thickness should be.

Second, the manufacture of plastic doors and windows. PVC doors and windows are generally used in the factory plastic doors and windows dedicated cutting, welding equipment, is semi-automatic, automatic production line, quality can be guaranteed.

3, buy windows and doors precautions. 1. To understand the selected UPVC door and window profiles. UPVC windows and doors of the profile is the decisive factor in the quality and grade. Good UPVC profiles should be more rational design of cavity wall thickness formula contains anti-aging, anti-UV additive. In appearance should be a plainer color and smooth surface. In particular, to remind you that there are a lot of people think that the white plastic-steel windows are the same is not true. High-end color should be white UPVC profiles in Fan Qing, the color of this anti-aging properties, in the outdoor weathered 35 years of not aging, discoloration, deformation. The medium and low profile white in yellow, the color is poor sunscreen use in a few years behind the yellow sun would be up to the aging of the more brittle deformation.

2. Do not buy cheap plastic doors and windows. Good steel doors and windows Plastic Quality, lined with steel quality, hardware quality are high, life can reach more than a decade. The use of cheap plastic doors and windows profiles, calcium carbonate content of more than 50% Additive Containing lead salts, poor stability, and affect human health. Lined steel is hot bar plate, the thickness is not enough, some did not even lined steel, Glass , Also have a bad hardware products. Life only in 2023.

3. Attention to assembly quality windows and doors. Is whether the smooth appearance of the main non-destructive, welded angle is clean and tidy, sliding window is sliding flexible, casement window is open freely, doors and windows are sealed tight, and that hardware is installed for whether the steel liner and so on. The surface of plastic doors and windows color profiles for the Qing Baise or ivory white, clean, smooth, Omo no scratches, bumps, no open mouth welding welding and fracture. Surface should be of good quality door and window protection film, protective film users to tear up before then.

4. Glass and metal parts can not be ignored. Glass should be flat, no waterlines. Glass and plastic profiles are not in direct contact with sealing layering closely aligns gap. Hardware is complete, the correct position, install a solid, flexible in use. High-grade doors and windows are made of metal hardware, its inherent strength, appearance, use of doors and windows have a direct impact on performance. Many middle and low use of plastic door and window hardware, the quality and life expectancy there is a major hidden dangers.
