Flooring boards. They are classified as flooring boards, flooring blocks, parquet blocks, etc. Generally, hard broad-leaved wood is used. (1) Flooring boards: A single board made of hinoki or zelkova, but often made of nara, beech, or lauan. It is about 1.5-2 cm thick, 5-10 cm wide, and 2-6 m long. The front and back are shaved, the sides are tongued and grooved, the ends are grooved, and a shallow groove is made on the back. (2) Flooring block: A type of parquet board. Three or four rectangular boards, each 1.5-2 cm thick, are joined together with glue or with corrugated nails on the back to form a 23-30 cm square. The back is waterproofed and the board is laid on the floor with asphalt cement or mortar and metal feet. Nara wood is mainly used. (3) Parquet block: A board for parquet laying. Pieces of wood with different colors or grains are combined in various patterns. The floor is then finished by applying adhesive to the floor. These wooden floorboards are inferior to plastic, stone, and ceramic floor tiles in terms of fire resistance, water resistance, and rot resistance, but they have excellent insulation properties, a pleasant feel due to their moderate elasticity, and are beautiful, so they have long been widely used in homes, offices, gymnasiums, etc. Other types include tiles made from cork, and sheets made from rubber or polyvinyl chloride.
