Wooden panel for walls floors and roofs

摘要

The panel is made up of at least three layers, two of which are located at 90 degrees to each other and the other intersect these at 45 degrees. Both spaced and non-spaced layers are available. The wood spaces regarding the spaced layers are filled with material for improving sound damping, insulation, fire protection,or other feature of the wood panel. The elements, built by the layers are composed of sorted or unsorted side boards (boards that, by the generation of wooden beams with rectangular cross sections are prepared from spar blocks for the purpose of a more efficient use of wood) and or scantling. The individual elements are joined with nails or screw connections to fulfil their static requirement (i.e. three layers joined together to effectively form a three way grain pattern).
