Due to the routing, these boards are prone to slight lateral bowing along the board's length. We have conducted tests for all designs on all boards and thicknesses and have found that the following bowing of the board, when measured from the middle:

  • 12mm — from 10-20mm
  • 16mm, 18mm, 19mm — from 3-10mm
  • 22mm — from 1-3mm

Although the boards bow, steps can be taken upon installation so that the bowing won't be noticeable.
