The cypress species, macrocarpa (Cupressus macrocarpa), Mexican cypress (C. lusitanica) and Lawson cypress (Chamaecyparis lawsoniana) have all been classified as moderately durable (durability class 3).
Abodo’s field test results from weatherboard panels, dating from 1988 prove that heart douglas fir (Pseudotsuga menziesii) to also be moderately durable, at the lower end of durability class 3.
After 22 years of field testing, uncoated heart douglas fir weatherboards had no sign of decay.
