Doors and windows are one of the indispensable main materials for daily decoration. They play an important role at home, such as heat preservation, heat insulation, sound insulation, waterproof, fire prevention, decoration, etc. No matter from the aspects of decoration and functionality, the function of doors and windows cannot be doubted! Therefore, in the purchase of decoration building materials, the choice of doors and windows is very worthy of attention. But now the doors and windows in the decoration building materials market are really rich in categories, which make people dazzling and the quality is even more uneven. In addition, the shopping guide is "full of flowers". After walking around the store, there is still no way to start, and there is no way to judge.
As the saying goes, it is good to be an expert and a layman watching the scene. For friends who don't know about doors and windows, buying doors and windows is really a headache. Here are three ways to choose doors and windows: one look, two touch, three try! It is simple, then what is it? What is it? What did you try? If you really want to know clearly, you still need to walk several circles in the decoration building materials market!
Let's give you some actual combat!
Take a look
first look at the corner to see if there are obvious interface gaps. If there are obvious interface gaps, they are basically produced by small shanzhai door factories;
look at the glass to see if there is 3C special LOGO printing on the glass. What is not there is not tempered glass, and the ability to resist wind pressure is poor. It is easy to cause human life damage after the glass is broken; Look at silicon sealant, check whether the glue is smooth and whether there are uneven images. Glue is the most direct way to let people see the technological level of this brand;
look at whether there is a drainage hole on the door and window frame. Many small factories have not hit the drainage hole, because for one or two drainage holes on the frame, it is really not worth adding a set of professional punching equipment and adding a process, but just because of this small drainage hole, the level of the industry is clearly divided.
These four views are very simple and common, but people can see them thoroughly. If they see so deeply, they can also be easily divided into the technological strength behind the door and window manufacturers.
Two Touch
first touch the corner and touch whether there is a high or low difference between the two materials. If there is an obvious high or low difference, it indicates that it is basically produced by a small factory and the process is simple;
then touch the holes with holes in the corner or other aluminum materials, and touch whether there are hairs on the hand. If there is obvious pain in the hand, it indicates that the production conditions of the manufacturer are simple, there is no large machine processing equipment system.
Three tests
try to open and close, push and pull, and try the actual effect. This is the most important thing. You can directly judge whether the doors and windows are good or bad and whether they are used after the day.
Break the handle and open the door and window for a try. Well, when breaking the handle, the door and window will feel that the handle is obviously staggered. When breaking it to 90 degrees, there will be a slight dull feeling of stopping, proof handle opening and closing reset. Inferior hardware basically doesn't feel like this. You should know that the price difference between good handles and inferior handles on the market is several times!
Try to open the doors and windows, good doors and windows ordinary adults can push them away with small force, if you don't push them away, it proves that the materials used for doors and windows may be insufficient, and the glass may be relatively thin, the sound insulation and heat insulation effects are not as good as they should be; In particular, the window may be opened by hinge, and the good doors and windows will adopt hinge. From the perspective of safety and beauty, Hinge and hinge are two levels, the price of the hinge is about twice higher than that of the hinge.
If it is sliding door, try whether the sliding door is smooth, whether there is a sound, whether there will be collision between the door leaf and when it is in place, and whether there is any anti-collision.
After a small test, you can generally judge the strength of the doors and windows brand you are looking at. It is impossible for the shopping guide to ask the price everywhere. The price is wrong! I hope you can buy well content doors and windows with high cost performance!
