Other names and DIN designation

With Spruce wood is often meant the wood of the North American Sitka spruce. Alternatively, one often finds the names "Sitka wood", "Sitka Spruce" or "American spruce".

Caution is necessary with the term "Spruce", because with this term all American spruce species as a whole can be meant (Engelmann spruce, white spruce and Bleck spruce). So you always have to specify exactly what you mean, because each of these spruce species has slightly different characteristics and a different and different frequent use.

Appearance

Grain

The grain is similar to our native spruce, but not completely identical, especially the sapwood is still well distinguishable in the American species. Pores are absent, resin channels are not visible to the naked eye. The annual rings, however, are clearly perceptible, the earlywood is always wider than the latewood. Overall, the structure looks very fine and decorative.

colour

The still recognizable sapwood is yellowish to whitish with partly gray tints. The heartwood is slightly pink to reddish brown and darkens to a lesser extent. American spruce species are therefore easily recognized by the Europeans due to their distinctly reddish color.

properties

The essential characteristics correspond as far as possible to European spruce. Spruce wood is very light, but has very good strength properties in view of the low weight. The workability is very good.

Shrinkage and drying

Even with the Spruce wood drying is quite fast, and relatively easy. The shrinkage behavior corresponds approximately to that of native spruce wood.

resistance

Like the native spruce, the Sitka spruce is not weather-resistant and only slightly resistant to fungal and insect infestation (resistance class 4-5).

use

As well as native spruce wood, Sitka spruce is also used in a variety of ways as wood for furniture construction, interior finishing and veneer wood. But unlike domestic wood, Sitka wood is also often used in boat building and musical instruments.

ancestry

Sitka spruces grow mainly in Alaska, but also on the North American West Coast. Some Sitka spruces are also grown in Europe, but then have a slightly lower quality and strength.

Tips & Tricks

Sitka is particularly suitable for painting and pickling (even better than domestic spruce). So for such surface treatments, you can grab well to Spruce wood.
