Moisture naturally affects the expansion and contraction of timber. Wood is hygroscopic, that is it absorbs and releases water to balance out with its surrounding environment. The fresh-cut wood beams are therefore kiln-dried to approx. 15% moisture content, which is suitable for indoor use. It takes 2-3 months of air-drying time and as many as 3 months kiln-drying time to reach the moisture level needed for further processing. CRAFTWAND®. Dried with wind, sun, green energy, and patience.
