Annual sawn timber production : 810.000 m3
Douglas Fir : Pseudotsuga menziesii
Originate from North America, Douglas-Fir has been
introduced in France in 1842. Wide-spread today, its
production keeps growing (+15% a year).
Its rapid growth gives birth to tall trees (50 meters),
with a large diameter (2 meters), straight-grained,
thick and checked bark.
Its reddish-brown heartwood is distinctive from its
cream white sapwood. Douglas-Fir is straightgrained,
with medium texture and sound knots.
Conditions of implementation
Oak heartwood has naturally high durability.
It is used without any treatment (Class 3: timber exposed to weathering). Sapwood is easy to treat.
After impregnation, Oak can be use in class 4 ( contact with water ).
