Does the floor have to be paved with layering?

Floor battens, also known as buckles, are generally used for joints between floors or doors. Because the wooden floor is made up of wood blocks, a large gap must be left in some cases. For the sake of beauty, they are covered with wooden strips. Divided into the following categories:

Skirting board: used for wall surface, which plays the role of shielding and pressing the floor and beautifying. Door buckle: the connection between the two areas also plays a shielding role. Right angle: divided into PVC and metal. Stair buckle: the floor is commonly used when making stair boards, and it is something that connects the elevation and plane of stairs.

It is best to use layering, which has three functions:

1, the region segmentation is obvious; 2, reduce the height of the gap at the bottom of the door leaf and increase the sound insulation effect; 3. Avoid the problem of thermal expansion and cold contraction.
