Straw Bale R Values
...on the relative humidity, and to a much smaller extent, the temperature of the straw. A straw bale left in a 70º F room with the relative humidity of 75% will have equilibrium moisture content (EMC) of 14.5%. Wood and straw have similar moisture-absorbing characteristics; moisture data generated for wood can thus be used to determine... See #3.
Kaswell & Company Understanding Acclimation of Wood Block Flooring
In so doing, you might install the block too dry during the heating season, and have problems during the more humid months. If you know the EMC or Equilibrium Moisture Content of wood in your region, it might be that the wood (block) brought to a jobsite might already be at the proper moisture content, and therefore acclimation... See #4.
Bridges - Sentinel Structures, Inc.
Many timber bridges in the past 10 years have used wood of high moisture content, 24-28% at time of construction and often beyond 30%. The equilibrium moisture content in service is not beyond 18-20%. As the wood loses moisture content to 20% or less, shrinkage beneath deck asphalt surfacing leads to that wearing... See #5.
