Woods/Man Made Boards

Woods
There are two types of woods softwoods and hardwoods.Hardwoods come from broad-leaved angiosperm trees,mostly deciduous, but not necessarily, in the case of tropical trees.
Where as softwoods come from which comes from conifer trees. On average, hardwood is of higher density and hardness than softwood, but there is considerable variation in actual wood hardness in both groups

Softwoods are sometimes harder than hardwood trees.Douglas fir, a softwood, is harder and stronger than many hardwoods, balsa is technically a hardwood, is much softer than even most softwoods.In general softwood is easy to work with.Softwood has a huge range of uses, it is a first choice material for structural building components, but is also found in furniture and other products such as millwork (mouldings, doors, windows).

Hardwood joinery is expensive compared to softwood. In the past, tropical hardwoods were easily available but the supply of some species such as Burma teak and mahogany is now becoming restricted due to sustainability issues.
