Window sealing is the frontmost part of home improvement and one of the most important products. Doors and windows are related to shelter from wind and rain, safety and convenience, and consumers also attach great importance to them. Most consumers only pay attention to aluminum thickness and profile width when choosing aluminum alloy doors and windows. In fact, they have entered a big misunderstanding. The thickness and width of the profile do not have any technical content, and it can be done by changing the model. Large and small factories can do it. The thickness has a great influence on the cost of doors and windows, but the width has a very small effect. The cost difference between the 110 series and the 120 series is within 5%. So which areas should be paid attention to?

First of all, the process is very important. For example, the seamless welding process of the whole frame is much more expensive than the ordinary splicing process. Of course, the aesthetics, durability and safety are also improved a lot. Moreover, the injection of glue at the corners is also very important, which affects the firmness and air tightness. The second is the profile structure, the cost of multi-cavity with sub-frame is much higher, and the sound insulation effect is also improved simultaneously. Profiles of high-end products are generally designed with vertical isothermal structure, and the heat insulation effect will be better.

There is also the brand. The brand strength is stronger, and the management, service, stability and innovation will be relatively better. It is also very important to choose a regular brand manufacturer. However, doors and windows are low-frequency products, and manufacturers generally do not spend too much money on brand promotion. There are almost no household-known aluminum alloy doors and windows. When choosing aluminum doors and windows, we must pay attention to distinguishing the quality of the actual products.
