Hello, there is no doubt that the higher the better, don’t mislead me below! When real estate developers sell houses, the floor level is linked to the price. Do you think they are fools? It is recommended to buy 6 layers for best. If there is a withdrawal of 7, then it is best to buy 6 layers. The reason is to ensure that there is a house on top of you. The advantages of this are: First, it prevents the roof from leaking, which will not immediately cause trouble. Second, there is an extra layer on top, which is equivalent to an extra layer of insulation, and your heating and air conditioning costs will be saved a lot. Moreover, the air quality is much better than down below, and it needs to be higher up near the road, so that the noise will have the least disturbance to you.
