SWP
3-layer panels
Description
3-layer panels NOVATOP are made of coniferous sawnwood dried to 8% (larch 12%). Each layer of the panel consists of lamellas of massive solid wood. The three-layer panel consists of one middle layer rotated by 90° relative to the outer layers. The thickness of the layers can differ and determines the final thickness of the panel. The lamellas of the middle layer are glued longitudinally, and lengthwise they are connected with the butted joint or they can be continuous. Their thickness is a maximum of 42 mm. The outer layers are made of continuous lamellas with a thickness of 6 or 9 mm and a width of 93-143 mm. On every panel, there is always the same width of the surface lamellas whose right side faces the surface. The longitudinal joints of the lamellas are glued together. The adhesive used is waterproof and the surface lamellas are glued according to AW 100, or possibly D4 according to EN 204. The quality of sanding corresponds to the grain size of 100 (coarser sanding is made to order).

Examples of application
Multilayer panels NOVATOP can be machined with all standard woodworking tools and machines as solid wood can. As for the surface finish, all methods used for solid wood are suitable. When used in the outdoor environment, the natural properties of solid wood must be taken into account.

Warning: The recommended relative humidity of the environment in which the NOVATOP panels are installed is 55 % at 20 °C. As a result of low air humidity, cracks may appear in the wood. Wood properties of this product are maintained, so they respond to changes in temperature and humidity by shrinking or, possibly, by swelling. Improper storage and use in extreme conditions (extreme temperatures and humidity) can cause cracking and deformations.
