Everyone chooses whether the wooden door is a solid door. Usually, it is judged by hand to judge whether it is solid, but there are many doors that you can't knock out whether it is solid or not. It is filled with filler, and it is no different from the solid door. Some owners use the method of moving weight to experiment. In fact, they can't try the same effect, because many manufacturers fill the door with a similar weight of wood, which can't be identified. First of all, whether the color of the door is matched with your own home, and then tapping to determine the quality of the door. The filling in the door is generally divided into solid and partially solid, the solid filling is definitely heavy, the price is expensive, and the part is relatively light and relatively cheap. However, there are also some black-hearted merchants on the market who use some scraps as fillers to increase the weight. Consumers should be careful when purchasing. Second, you can consult the closeness of the staff door. That is to say, the "seal strip", which is in the contact part of the door cover and the door leaf, is soft to the touch. Regular companies will add sealing strips, which avoids the problem of a seam after closing the door. Again, it is to ask about the material of the door cover, because most of the wooden doors have problems, mainly because the door sets have problems. The essence of the problem is that the merchant does not necessarily use the same material for the door cover and the door leaf. The solid wood door leaf does not mean that the solid wood door cover will be used. If the solid wood door is made of a MDF, since it does not contain wood fiber, it is easy to foam when it is in contact with water, which will cause the door frame to be deformed. Therefore, it is best to ask whether the door cover and the door leaf are a material at the time of purchase.
