Balsa is the lightest and softest timber used commercially. It
exhibits an unusually high degree of buoyancy and provides very
efficient insulation against heat and sound. The wood can be
adapted to a great number of special end-uses where these
properties are essential. The timber is white to oatmeal in colour
with sometimes a pinkish tinge near the hart. Still most commercial
material is from the sapwood. It has a coarse and even texture
resulting from the large and infrequent sap conducting vessels.
Straight grain. It is a short lived fast growing tree native to
tropical South and Central America but it is widely cultivated in
the tropics. Trees grow to 21m high and diameter of approximately
0.5m within seven years, reach maturity in 12-15 years after which
they deteriorate with increases in density leading to the formation
of hard and heavy wood and heartwood which tends to become
waterlogged. Although when planted outside their natural range, the
wood produced tends to be heavier and outside the commercially
accepted density range for balsa the species has been planted
successfully in Papua New Guinea, Malaysia, Fiji, and
Indonesia.
Characteristics of balsa wood make it a unique hardwood albeit,
when weight for weight basis is excluded, it is the weakest of all
commercial species. The logs must be converted promptly after
felling to prevent extensive splitting. Kiln drying is preferred to
air-drying due to low moisture movement and very high green
moisture content (200-400%). The timber works well with tools but
cutting edges must be sharp to avoid crumbling and to ensure a good
finish in planning. Material can be nailed, but its holding power
is poor. Glues well, stains and polishes satisfactorily but it is
very absorbent. Timber is prone to attack by Anobium, termites and
longhorn beetle. The sapwood is permeable, heartwood resistant to
impregnation. Timber cut form old trees is often brittle and
decayed.
Traditional uses include: surf boards, laboratory mounting boards,
fish net floats, aircraft construction and model making.
