Nowadays, thermally-insulated aluminum doors and windows are very popular in the market. As a professional installer, I would like to share with you some practical suggestions for purchasing thermally-insulated aluminum doors and windows.

Thermally-insulated aluminum doors and windows have many benefits. It is not only fireproof and heat-insulating, effectively preventing the spread of fire and heat transfer; it can also reduce noise, and the carefully designed structure can isolate external noise, allowing you to enjoy a quiet life. At the same time, thermally-insulated aluminum has high strength, no deformation and maintenance-free, and the straight hollow design of the inner frame makes it excellent in wind pressure and vibration resistance. In addition, it is available in a variety of colors and has strong decorative properties.

When choosing thermally-insulated aluminum doors and windows, pay attention to the following key points: First, be sure to check the thermally-insulated aluminum code, which is the anti-counterfeiting mark of the profile manufacturer, which is usually difficult to wipe off. Do not choose products without code; second, observe the surface of the thermally-insulated aluminum. High-quality products have high gloss, good texture, and natural and smooth color spraying, while poor products lack gloss, have a rough surface, and may fade; then, pay attention to the wall thickness and section of the profile. The national standard stipulates that the thickness should be above 1.4mm. Products that are too thin will affect the sealing, sound insulation and thermal insulation effects. The section should be of appropriate thickness and correct angle. If there is bending or twisting, it is inferior; finally, the insulation strip is crucial. Be sure to choose imported pa66 nylon (European style) specified by the national standard. Its quality directly affects the thermal insulation effect and service life.

In addition to the material, the overall process cannot be ignored. Find a professional manufacturer to produce, ensure that the materials, hardware and glass meet the national standards, and install them reasonably, so that the value of the thermally-insulated aluminum doors and windows can be truly brought into play and your money will be worth it.
