Moisture content in new vs. old wood
My question is about moisture content of new versus 100 year old wood found in an attic.
I was recently in an attic and noticed dripping condensation in the vintage home's attic. The dimensional lumber planking used as roof sheathing had a few new white pine planks installed. With a pin type moisture meter, the MC in the new white pine was 22%. In the adjacent softwood (SPF?) the MC was twice at 40%.
Does an attic do funky things to wood long term? Certainly the sap has dripped out over repeated summer heat and maybe the wood has a greater capacity to absorb moisture?
The meter suggests no number over 30MC should be trusted. I also should have corrected for temperature and for species.
