Kiln Dried After Treatment, or KDAT is a process that removes excess moisture from lumber, minimizing the natural characteristics of wood to shrink, cup and warp. KDAT minimizes shrinkage and promotes stability in the system.  Kiln drying decreases the finished weight of the system 30% – 40% as compared to leaving it wet.

KDAT material is:

  • Lighter weight and easier to handle
  • More resistant to warping and twisting
  • Easier to saw and plane
  • KDAT improves the holding power of nails and screws
