Our Solutions

Our primary product is Castellated© lumber. It is produced by segmenting a rough-cut unit with a Castellated© cut, rotating the segments, then reassembling, gluing and pressing them before kiln drying. The Castellation© steps can be inserted into the traditional dimensional lumber production process between green sorting and kiln drying.

Reassembly, gluing & pressing

Of the many applications for Castellated© lumber, replacing dimensional lumber used in framing is a stand-out. Castellated© lumber can transform the construction process: It eliminates rough-trades installation core-drilling owing to its intrinsic midline holes, enhancing accuracy in the construction process and maintaining a cleaner site. Intrinsic handholds and lighter weight facilitate easy handling and a reduction in load-bearing for construction team members. Overall, timber framing in Castellated© lumber unlocks shorter construction lead times.

Further up the wood construction value chain, Castellated© lumber provides yield improvement, energy savings in kiln drying time reduction, minimal processing waste, up-graded output and a lighter freight-friendly premium product, all of which can contribute positively to sawmill profitability.

Castellated© lumber is just the beginning for AddWood…
