Fumed Douglas Fir Veneered Panels & Jointed Veneer
Fumed Douglas Fir veneer is produced by passing the naturaldouglas firWood through an ammonia kiln to permanently change its colour.
This process gives the wood a much darker, exotic colouring that has a more '3D-like' character, and is more UV stable than the natural wood or any other form of colouring, e.g. dyed veneers. Its improved UV-stability makes it more resistant to bleaching after prolonged exposure to the sun.
Also known as British Columbia Pine and Oregon Pine, Douglas Fir can be found in central & western North America from Mexico to central British Columbia. in 1880, the species was introduced in the north of Germany to enrich the tree composition of German forests with foreign species and this is now a most important source of Douglas Fir, especially Fumed Douglas Fir.
Douglas Fir sapwood is whitish to pale yellowish and narrow in old-growth trees but as much as 7cm wide in second-growth trees. Young trees have reddish heartwood, while very narrow-ringed heartwood of old-growth trees may be pale yellowish brown. The grain is usually straight, sometimes showing curly or wavy characteristics displayed best on rotary cut veneers from old and large trees.
Douglas Fir veneers with narrow growth rings are quite uniform in texture while those with wider rings are very often uneven textured.
