Abstract

The effect of drying conditions on gas permeability and preservative treatability was assessed on western hemlock lumber. Although there were no differences in gas permeability between lumber dried at conventional and high temperatures, there were differences in preservative penetration. High-temperature drying was associated with improved penetration of ammoniacal copper zinc arsenate and reduced penetration of chromated copper arsenate. The reasons for these effects are unclear.
