Sweet chestnut is a hardwood found in South
west Europe, Australia, North Africa and Asia. It's a very
strong wood much like oak, but not as strong. It cleaves well (see
picture No.5) when the grain
is straight and should always be pre-drilled before nailing
because of its tendency to split. Sweet chestnut is a wood that
highly recommends for roundwood timber framing, wind braces,
cladding and shingles.
