A wood structure will not last long if it is not
properly protected against environmental conditions and pests. While a
number of hardwoods have its own natural protection in the form of
tannins bound in cells, density of the wood, hardness and other
natural protective measures, giving all hardwoods a significantly longer
life time compared to soft wood, it needs to be treated and maintained
to extend the life time and protect it from exterior factors not dealt
with. In addition the moisture content , - called MC -, before the wood
is worked, cut and planed is of crucial importance for its life time.
These protective measures are: coating, kiln drying
and anti termite measures. At the left we present a number of links tp
pages where you can read all details.

species which are generally used in prefab wooden house building.
