Fumed Larch Veneered Panels & Jointed Veneer
Fumed Larch veneer (also known as Fumed Siberian Larch) is produced by passing the natural larch veneer 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.
Larch is a most unusual conifer in that it is deciduous and therefore drops its leaves in autumn. It is found right across the Northern hemisphere in Europe, Asia and the north-western US in the form of three different groups. The Asian and European larches have been cross-bred to create a hybrid that has high growth potential and resists larch cancer very well.
Larch wood changes abruptly from early wood to late wood. That can easily be seen from the growth rings. The late wood is also darker than the early wood. The heartwood is yellowish brown to orange & golden-brown, darkening in the light and with age, is well demarcated from the sapwood, which is generally not more than 3cm wide, and yellowish white in colour.
Although in general Larch is inclined to exhibit small and tight knots, when it is well grown the best logs can be very straight grained and free of knots.
Finishing fumed larch veneer correctly poses no problems. The resin-rich parts should, however, be degreased before finishing the wood with paint, varnish, wax or stain.
The properties of Larch veneer are similar to those ofDouglas Fir, and these species are sometimes sold mixed together.
