There are many kinds of door materials, such as composite doors, glass doors, solid wood doors, etc. Now many friends will choose composite doors. How to choose composite doors correctly? How to choose and purchase composite doors correctly? 1、 Appearance: 1. Look at the edge sealing. Since the professional manufacturer uses modern machinery and equipment, and adopts imported glue for high-temperature and high-pressure edge sealing, the exterior surface of the living room should be flat and firm after edge sealing. 2. Look at the hardware accessories. In addition to the manufacturing process of the wooden door itself, the quality of hardware also affects the service life of the wooden door. Hinges are a kind of hardware connecting wooden doors and door frames. Good hinges have anti-corrosion performance and good transmission, which can ensure that the hinges are evenly stressed and will not be damaged due to the weight of the door. 3. Look at the environmental protection of materials. All raw materials are environmentally friendly materials to produce environmentally friendly products. It is better to have the inspection certificate of the environmental protection department. 4. It is also crucial to see whether the manufacturer has its own service system. When signing a contract, consumers should indicate in the contract that the manufacturer is responsible for the delivery, acceptance and quality problem solving during the warranty period. 5. The quality of wooden door manufacturing process directly affects the service life of the door. Generally speaking, the wooden door is prone to deformation, cracking and other phenomena after being used for a period of time, thus reducing the sound insulation effect, sealing and various properties of the door. Therefore, the wood door with guaranteed manufacturing technology is not easy to deform and crack due to its low wood moisture content. 6. The sound insulation effect of a wooden door depends on the material of the door and the detail treatment during processing. Since the sound insulation performance of the door is achieved by reducing air flow, the higher the density of the door, the heavier the weight, and the better the sound insulation effect. 2、 Indoor environment: 1. When the living environment is warm, you can choose a warmer color system relative to the wooden door, such as cherry wood, teak, Sabri, etc. When the living environment is cold, you should choose a lighter wooden door, such as oil mixed white, birch, etc. 2. The color of the ground should be consistent with that of the wooden door (such as cold and warm), but it is better not to be consistent. Prevent the floor from being confused with the wall, and weaken the sense of room space. 3. For large or sunny rooms, darker black walnuts can be selected to create a calmer atmosphere. The color itself is beautiful, and there is no right or wrong. It's all about matching and coordination. If you are really unsure, you should choose white, which is the least error prone color!
