In the door and window industry for many years, I found a very common problem, that is, some consumers have difficulties when buying doors and windows in their homes. They have no clue when facing so many brands and types of doors and windows. Thousands of choices, hesitate. Let me tell you today what to pay attention to when buying doors and windows.
One is the profile. When we buy in the store, the first thing we should pay attention to is the quality of its profile. Generally speaking, there are two main types of aluminum currently circulating on the market, one is recycled aluminum, and the cut and surface are rough and dull. Light, and the material is “brittle”.
When a regular large-scale manufacturer like the door and window superhouse is producing, they are very particular about the choice of raw materials for doors and windows, so they will use another type of aluminum-primary aluminum ingots. Its toughness, gloss, adhesion, bearing capacity are relatively good, and the incision is flat, high density, and strong hardness. We can observe the surface more when purchasing, and test it with hand pressure.
Secondly, we must pay attention to the choice of glass. We have four common ones, such as: hollow ordinary glass, single-layer ordinary glass, single-layer tempered glass, and hollow tempered glass. Each has its own characteristics, such as hollow tempered glass, which has good impact resistance and bending strength, which is 3-5 times that of ordinary glass. Even if it is broken, its fragments will become honeycomb-like obtuse-angle particles. , Will not cause harm to the human body.
It is necessary for us to examine the quality of its hardware accessories. Many manufacturers now use poor-quality hardware accessories in order to save costs, which will affect the service life of doors and windows to a certain extent. Many users only pay attention to its appearance while ignoring its hardware durability. It is important to know that the quality of hardware accessories will affect the opening and closing feel, flexibility, safety and service life of doors and windows.
