Natural Timbers

Lumer has been failed, still in its log shape

Wood is the material

Timber is the processed material

Hardwoods - Diciduous trees, loose there leaves in the winter
(Ash, oak, beech, teak, walnut)
Slow growing

Softwoods come from coniferous trees, trees with needles and cones, evergreens
(larch, spruce, scots pine, douglas fur)
Fast growing

Indiginous - point of origin (oaks from england)

Softwoods are cheaper to buy due to it being able to grow quicker, it is a more sustainable source than hardwoods.

The age of a tree can be found out by counting the amount of anual rings

the dark rings show the winter months, light rings show the summer, thickness determins how long the summer or winter was. In the winter the lines are dark due to the resin protecting the tree from the cold and in the summer less resin as it isnt as cold.

FSC symbol is placed on wood to show it is from a sustainable source, for every tree they cut down they replace it with two.
