How to buy high-quality doors and windows, what are the tips?

Doors and windows are essential building materials in our daily decoration. With people's attention to home decoration, the profiles of door and window products are becoming more and more diversified. Nowadays, aluminum alloy doors and windows are more popular than other profiles of doors and windows with their high thermal insulation, sound insulation, wind pressure resistance, water tightness and other performance advantages. How to buy high-quality doors and windows? This question makes consumers feel very anxious. Let us introduce it to you below.

1. Materials

The main materials for doors and windows generally include three aspects: aluminum profiles, glass, and hardware. When owners buy door and window products, they often pay more attention to the thickness of aluminum profiles and glass, but the requirements for hardware are not very high, which is not comprehensive. In fact, the requirements of the country's colorful aluminum windows are certain standards. The aluminum profiles used for high-quality color aluminum windows generally meet national standards in thickness, strength and oxide film. For example, relevant national regulations require that the wall thickness of the aluminum profile of the color aluminum window should be above 1.2mm, and the thickness of the oxide film should reach 10 microns. Tempered glass is better than ordinary glass. If the safety and durability of doors and windows are considered, stainless steel hardware accessories (such as screws, hinges, etc.) are better than aluminum accessories, and it is better to choose POM products for pulleys, because such products have higher strength and wear resistance, smooth use, and are not easy to break. You should know that damage to doors and windows usually starts from door and window accessories!

2. Processing

With good materials, the next step is the processing of doors and windows. Since the technical content of doors and windows is not high and the degree of mechanization is not high at present, most of them still rely on the manual operation of installers, which requires operators to have a good sense of product quality. It is very important to enhance the proficiency of operators and product awareness during the production process. High-quality aluminum alloy, fine processing, smooth tangent, consistent angle, there should be no obvious gaps in the splicing process, good sealing performance, smooth opening and closing. If the processing is unqualified, there will be problems with the sealing properties, not only air leakage and rain leakage, but also under the action of strong wind and large external force, the glass will burst and fall off, causing property losses to the owner or even injury.

3. Performance

The performance of doors and windows has different focuses due to different scopes of use. Usually, several aspects should be considered: strength, which is mainly reflected in the selection of materials for door and window profiles, whether it can withstand high pressure airtightness, which is mainly reflected in the door and window structure, whether the inner leaf and outer frame structure of the door and window are tight, and whether the door and window are tight.

4. Price

Since the price of doors and windows is directly related to the price of aluminum ingots, the price of doors and windows is generally relatively stable in a certain period of time. Under normal circumstances, the price of high-quality doors and windows is 30% higher than that of inferior door and window products. Inferior doors and windows usually use aluminum profiles extruded from recycled aluminum containing a large amount of impurities, and the wall thickness of some aluminum profiles used is only 0.6-0.8 mm. Both the tensile strength and the yield strength are much lower than the relevant national regulations. This type of doors and windows is very unsafe, so owners should not be greedy for a momentary cheapness when purchasing door and window products, and neglect the life safety of themselves and others.

5. Appearance

When purchasing door and window products, customers usually pay attention to the appearance of the product and the decorative pattern of the glass, but often neglect the composite film on the surface of the door and window. The composite film is formed by the coloring of the thermal oxidation film, which has corrosion resistance, wear resistance, high gloss, and certain fire prevention functions. Therefore, when purchasing aluminum alloy door and window products, you should compare more similar products. The glass process varies from person to person, and different owners have different requirements according to their own
