If the floor with a thickness of 0.8cm can meet the requirements of ground bearing, then 0.8cm will do. Because in the case of floor bearing, the thinner the floor, the better the heat dissipation effect. Personally, 1.2cm is good. 1.2 Although it is not worse than 0.8, the thicker the floor, the more empty it will feel. If the ground is warm, the heat will be dissipated indoors, that is, the heating time will be longer.
You can observe it on the composite floor to see if the joints between tenons are uneven and tight. Then you can use more than one floor to assemble yourself, and observe whether the combination of tenon and groove is tight and smooth. In terms of material selection, the quality grade of rubber wood and pine wood in the middle layer is higher, followed by willow. Multi-layer solid wood composite floor mostly adopts multi-layer plywood, and the surface decorative board adopts hardwood layer, and the thickness is generally between 0.2 and 0.8 mm. ..
The middle layer of solid wood composite floor not only increases the feeling of feet, but also prevents the expansion and deformation of the floor. The thickness of the floor should be about 8 mm, and the quality grade of rubber wood in the middle layer is higher in material selection. Multi-layer solid wood composite flooring is usually based on multi-layer plywood and the surface decoration board is hardwood.
