Available in 1220 x 2440 mm and 610 x 2440 mm in 17.5mm thickness

  • CSA Certified Panel
    All of our products are built to meet CSA O121 for Douglas Fir Plywood and undergo rigorous inspection and testing by our Quality Control team.

  • Hi-Flow MDO Paper
    Crown 44 panels come standard with our high resin content Hi-Flow MDO, providing a more durable working face than our standard matte MDO options.
