Permanence of warp reduction in press-dried plantation loblolly pine 2 by 4’s

Results from a 1987 study showed that press-dried, 8-foot-long, plantation-grown loblolly pine 2 by 4’s showed less warp and downgrade than kiln-dried 2 by 4’s. The purpose of this study was to determine the permanence of this warp and downgrade reduction after approximately 1 year of storage. After the year of storage, the press-dried 2 by 4’s still showed considerably less warp and downgrade than the kiln-dried 2 by 4’s.
