Product Description
Birch timber is sourced from birch species like Betula Pendula
(lat. Betula Pendula) and Betula Pubescens (lat. Betula Pubescens).
Other Birch species also grow in Central Europe however due to
their small size (grow short) they have no economic value.
Most birch density would be approximately about 650 kg/m³ (with
moisture level content of 12-15 %). Due to this physical makeup,
birch wood maintains the stress-grades of an average to
high-density timber species. The birch lumber has an medium
hardness, being elastic and viscous and is highly resistant when
folded and difficult to split.
Birch is relatively easy treated with hand tools, and quite widely
in handcrafting. Machine processing used to plane, mill and more
can be used to manufacture bent timber details with often
outstanding results.
Birch Timber boasts excellent bending properties while maintaining
it’s hard to split integrity. General manipulation practices
include glueing, nailing and screwing birch wood details together
or with other materials.
Durability and Treatment
Birch lumber needs to be treated with special protection to be used
in high humidity environment, and to protect it against potential
rots and fungi. Properties of wood Betula Pendula and Betula
Pubescens are very similar. Fluffy birch species are of finer
fibre, and produce a harder wood.
