Floorboards N15 are made of high-quality pine saw logs, and are glued in length and width. These boards can be used for indoor floors. To prevent deformation of the floorboards during operation, they are industrially dried and contain 14% (+/- 2%) moisture. There are two classes of floor boards available: class 1 and class 2, both have a smooth, planed surface. After purchase, the materials should preferably be stored in a dry space with low humidity.
