One of the most crucial fundamentals to woods strength and performance over time is to consistently dry the wood to its optimum moisture content (MC). The two methods of drying are Kiln-Dried (KD) or Air-Dried (AD).
Kiln-Dried lumber uses a highly sophisticate process of computer and operator controlled heat and humidity to adjust and regulate the drying of the lumber. KD has an enormous advantage, not only is the wood dried uniformly to a precise 12-14% MC; the wood is stable and shrinkage is done, losing most its water during the drying process, resulting in far less weight. With true Kiln-dried wood, there will be no Kiln stick-marks or mold on the wood.
Our KAYU wood is carefully monitored by Kiln dryers that are highly technical and have the advantages of modern-day computerized programming. Proven drying cycles that are extremely accurate and consistent; load to load and board to board. KD is far superior to AD with highly consistent results.
Air-Dried lumber is typically left to dry outside in inconsistent areas and conditions, weather and length of time. AD typically results in large variations of moisture percentages and quality. The problems that occur with the AD process is often with the wood not drying evenly and a 22-35% MC, which may vary from load to load and board to board. Worse yet, many loads ship on sticks in the “green/wet” state, resulting in moldy and sticker stained wood.
AD is an outdated process that is substantially less costly than KD. Although an outdated process with inconsistent variations; many mills simply can’t afford the finances for KD dryers and have no choice but to continue with the dated AD process.
At KAYU® International, we value consistency,so all our wood is 100% Kiln-Dried
