As one of the very important links in the process of house decoration, doors and windows not only affect the overall visual effect, but also meet our requirements for room comfort, warmth and safety. Doors and windows integrate profiles, hardware, glass, auxiliary materials and other materials need to consider aesthetics, structural mechanics and transmission control of photothermal energy, noise control, wind pressure resistance, air tightness, water tightness, ease of use, durability, weather resistance and many other factors.

many people think that doors and windows are qualified as long as they do not affect the normal opening and closing of Casement. In fact, high quality of doors and windows are qualified except for the selection of raw materials and the rationality of the structural design of doors and windows, the requirements for enterprise production are also extremely high, and it is difficult to produce quality products if they are crude.

look at the angle
the final quality of doors and windows has a relatively large relationship with the processing capacity of the processing plant. One of the important indicators is the corner setting. The connection between the two profiles at the corner of a good door and window is connected by aluminum corner brace, use corner combining machine to squeeze the profile and angle code together, and then inject two-component glue into the hole to solidify the angle code frame. Common low-quality practices include: no angle code splicing, no curing glue with angle code. In addition, the quality can also be judged by touching the stitching of the corner by hand, and the smoother it is, the better the processing quality of the corner is.

look at the adhesive tape
sealing refers to the sealing degree of doors and windows, including the sealing between glass and frame, the sealing between frame and frame after closing doors and windows, and the sealing between doors and windows and wall after installation, they jointly affect the sealing performance of doors and windows. However, sealing strips determine the sealing degree of doors and windows. At present, there are mainly two kinds of sealing strips on the market: one is wool sealing strips and the other is rubber sealing strips. Wool sealing strip and rubber sealing strip have their own disadvantages. Wool sealing strip is easy to remove hair after long use, which greatly reduces the sealing effect. However, the rubber sealing strip is easy to harden and age after being exposed to the sun and rain, which also reduces its sealing effect.

look at hardware
for doors and windows, hardware is the most superficial thing, so the selling points of many door and window factories are also on hardware. The quality of hardware mainly comes from reasonable design, proper materials and finely processed. Hardware is the main factor that determines the quality of the whole window. The quality of hardware accessories of doors and windows largely determines the service life of doors and windows. Its advantages and disadvantages mainly depend on its flexibility, sealing performance, wear resistance and corrosion resistance, high quality hardware is adopted to continuously improve the integrity of the system.

look at the glass
glass has always been a weak link in home decoration doors and windows, occupying 80% of the whole area of doors and windows.

Many door and window manufacturers will avoid talking about Glass, mainly because most of the processing plants are small factories.

door and window size
when the door and window corner or middle joint is spliced, it is misaligned at 45 degrees or 90 degrees. When the casement or window frame is connected, the joint is uneven, resulting in improper closing, poor air tightness and even water leakage.
