White Wood

Spruce (Picea abies)

General description

The species is widely distributed throughout continental Europe and is a timber tree of major economic importance. The large tree usually has a straight, cylindrical trunk and grows to a height of about 30 m (up to 55 m), with a large diameter of about 60 cm (up to 1,5 m).

 

 

Wood description

The colours range from creamy white to light yellow and to red-brown. Heartwood is not distinct from sapwood. Spruce is straight-grained with thin and regular texture. Resin canals are rather common. The wood is soft, low in weight and has medium density. The strength properties are good.
Sawing and machining is easy, also assembling. Spruce has a slight tendency to split when nailed.

Common uses

The typical end-uses for spruce wood are for structural end uses, indoors and outdoors, thus it is the most important building and construction timber in Europe. It is also used for decorative plywood, decorative veneer, domestic flooring, factory flooring, general carpentry, interior construction, joinery (external). Spruce wood from Central and Eastern Europe shows exceptional resonance qualities and is used for musical instruments like sound boards of pianos and bellies of violins and guitars.

 

Fir  (Abies alba)

General description

Fir is a typical tree growing in the shadows of higher trees. It is distributed over the whole of Europe, has a straight trunk and grows to a height of about 40 m

Wood description

The colour is white with a little tendency to grey-violette. Heartwood is not distinct from sapwood. The texture is fine to medium according to growing speed. There is no resin in the wood. The wood is similar to spruce: soft, low in weight and has medium density. Strength properties are good.
Sawing and machining is easy, also assembling. Fir also has a slight tendency to split when nailed.

Common uses

Fir and Spruce wood are often mixed for structural end uses, indoors and outdoors: general carpentry, interior construction, windows and doors.
