Kiln-Dried Traditional Timbers
The Kiln-Drying Process
Kiln drying is a complex science. The process controls the amount of moisture in the wood products used to build your Timber Frame or Hybrid Home. A large stack of timbers/cants is placed in a sealed building and the temperature is slowly raised to 170°F. Large reversible fans circulate the heated air to help maintain a consistent drying rate. The moisture-laden air is removed from the kiln by dehumidifiers. The drying rate is carefully monitored to prevent an imbalance that can cause cracking. When finished the moisture content of Timberhaven kiln-dried timbers is less than 19% average per timber.
Determining the Final Moisture Content
Timberhaven Log & Timber Homes uses the accurate “oven dry” ratio method to determine the final moisture content of our timbers. Samples of the kiln-dried lumber are weighed and then dried completely in an oven and weighed again. The ratio between the two weights represents the average moisture content of the timbers, inside and out. This is a much more accurate method of measuring the moisture content than using a “moisture meter” to measure the outside portion of the wood, which tends to be the driest.
