Will wood that is kiln-dried absorb moisture and/or give up moisture quicker than wood that is only air-dried? We would like to provide a humidity-controlled storage building for our kiln-dried lumber, but can't afford it now. What is the best way to keep moisture content of milled and un-milled lumber in check? It seems that wood inside a "dead piled" pack of lumber has an okay moisture content compared to that on the outside.
The US Department of Agriculture has a nice book on lumber storage. See the list of publications at WOODWEB's Bookstore:
Do you know that heating a storage area about 25 F above the outside low temperature will give you suitably dry conditions?
If you have a tight pile so that only 1% of the lumber is on the outside, plus the ends of all pieces (which pick up a little MC), maybe when you use this lumber the 1% or so of the pieces and ends will end up in 10% of the pieces that you are making and give you or your customer trouble. Storage is important.
