This breaking down of the fibrous nature of the
timber is evidenced by something that looks like a fur or hair covering of the
timber surface, often orange/red in colour.
Found in coastal areas and areas where manufacturing processes
release chemical fumes and gases. Infact, fumes released from slow combustion
stoves when discharged into roof caverties, cause a faster rate of this
de-fibering effect than salt air. Because Douglas Fir and radiata pine timbers
are most often affected this way, we expect the occurrence of this problem to
increase significantly in the future because these timbers have been used
widely in buildings over the last 20 years. However it occurs both in pored and
non-pored wood.
