ASH

Ash timber includes numerous kinds of woods, especially found in North America and Europe.

Description

Botanical name: Fraxinus excelsior
Overall character: Highly structured, decorative hard wood with porous rings, a high elasticity and a variety of colors that range from off-white to olive to brown.
Color and structure: Ash sapwood is white to yellow and very wide (up to 19 centimetres). The heartwood keeps the light yellow color of the splint. In old age, an optional color core can form.
Characteristics/features: The natural durability of the ash as well as its color core, is poor according to DIN EN 350, which places it in durability class 5 because the core materials are not encrusted in the cell walls.
Areas of use: Due to the low natural durability, this wood is mainly used indoors. Here it is especially suited for decorative veneers, flooring, stairs and furniture. Ash timber is also used for items that are very dynamically challenged, such as sports equipment, tool handles, ladders, boat paddles and musical instruments.

BEECH

The Beech makes for about 15% of the German forest area, making it the most important leaf tree of the country. Due to newer silvicultural concepts, an increase in beech wood is to be expected.

Description

Botanical name: Fagus sylvatica
Overall character: A light, homogenous simple wood with a solid and dense surface, that is characterized by its wooden rays.
Color and structure: The sapwood has a grey-pink to yellow tint and occupies the entire cross-section of the trunk. A red core can develop over the years (starting after approximately 80 years).
Characteristics/features: Pursuant to DIN EN 350, the natural durability of the beech, including that of the red core, is poor (durability class 5), since the core materials are not encrusted in the cell walls.
Areas of use: Due to the very good strength properties, hardness and the sleek appearance, the un-cored Beech is requested for production within the uniform furniture and door industry as well as for stairs, floors and plywood peeled veneers.

OAK

Oak timber includes all woods of the speciose Quercus species within the Fagaceae family. Because it can differ immensely in look, structure and technical characteristics, Oak timber is divided into three sections: white, red and evergreen Oak.

Description

Botanical name: Quercus spp.
Overall character: The porous rings and large wood rays give this wood a significant structure. The light and medium brown colored colored versions of this wood are mostly part of the white oaks, while the pinkish brown toned woods belong to the red Oaks.
Color and structure: Depending on location, age and species, the splint has a width of 2-8 centimetres and a white to light grey (white oak) or light grey to pale pink (red oak) color. The heartwood has a light brown leather color, and sometimes can have a reddish brown hue. Red Oaks can be a light reddish grey or light brown shade.
Characteristics/features: White oak heartwood has a good resistance against wood-destroying fungi, whereas the unprotected red oak is only moderately durable and unfit for outdoor use.
Areas of use: Due to their similar strength properties, white Oak and red Oak can be used in the same ways in (interior) construction and in equipping (living room, office and kitchen furniture, wall and ceiling coverings, solid wood and prefabricated parquet, wood pavement, stairs).

Characteristics/features: Robinia is one of the few wood species cultivated in Europe that are classified in durability class 1-2 pursuant to DIN EN 350).
Areas of use: The Robinia is suitable for outdoor use with ground contact as well as for decorative indoor use. In outdoor areas, the wood is used in gardening and landscaping, on children's playgrounds and in frame construction.
