The designed panel works as a truss structure. The Kerto LVL panels are cut: Kerto LVL panel (2.5x15) = ax4 = bx5 From a and b pieces are created large panels (4.2 x 15) = ax2 + bx6 For additional strength can be used wider connection panels of the rectangular shape. For 10 large panels 4,2m x 15.0m: 17 panels of Kerto LVL 2.5m x 15.0m. The percentage of wasted material is 1% (the amount of waste material from the saw is also calculated and is within 1%).

Key benefit

Small amount of the wasted material, strong panel, works similar to the truss construction

  • This is a great idea. It is simple, efficient, modular. The height of the wall can vary just as the beams above to suit the wall situation. A very efficient way to create large LVL panels. The exact joint geometry needs considering for stability an production, though.
  • The idea looks simple and efficient... A good one I'd say. Even more, top and bottom chord could be thicker beam, so that the entire wall is a king-size I-beam. What do you think?
