The lining is a lining board, which has a thickness of 22 mm, and is made from a trimming board. This happens by stricting one or both sides of the boards, as well as make a selection of side surfaces or a shpuntovka. Spoon is a kind of lock that is similar to the one that is used in the manufacture and installation of parquet. The lining can also be plastic. Plastic is good because it is not amenable to rot, mold and damage to fungi. On average, it lasts 8 years longer than wooden. It is good that the lining has not a very high cost and is an excellent material for lining the facade or interior.
