Kiln dry timber moisture controlWhen we kiln dry our timber, we do so in a controlled environment using carefully monitored temperature and humidity levels in order to avoid over-drying or under-drying. This is critical because it allows the wood to dry to the correct MC for its ultimate intended use, thereby enabling the wood to maintain stability and dimension. Wood that is over dried or under dried will warp or shrink and will not have the correct MC for its intended use.Depending on its final use, kiln-dried woods are dried to a specific MC range. For example, timber that is intended for export to Far East is dried to a range of 14-16% MC. Wood that is intended for outdoors, such as lumber used for framing a house, may be dried to a range of 17-19% MC.
