Wood properties

Board is a natural humidity and drying chamber. Dry board has a high strength, as well as it is not deformed and does not shrink, is very important for carpentry structures. Board of natural humidity is much cheaper, since it production cost and time manufacturing costs are much lower. Choose the board correctly, based on their goals and objectives.

Our drying chamber for the timber meets the requirements of European standards. In it we get the wood moisture content of 8-10%.

According to the degree of density wood is divided into three main groups:

  • Softwood: fir, cedar, pine, fir, juniper, linden, aspen, poplar, willow, alder, chestnut.
  • Hardwood: larch, beech, birch, oak, elm, elm, sycamore, maple, mountain ash, walnut, ash, apple.
  • Very hard wood: Acacia white, box, hornbeam, dogwood, birch, steel, pistachio tree, yew.

Of course, carpentry hardwood – more durable than from soft. However, this does not mean that only hard wood used by carpenters. Each species of wood are plenty of other properties that have become virtues. To try to understand some of them.

Pine

соснаEvergreen monoecious tree of the pine family, up to 45 m. The trunk diameter of up to 1 m, covered with reddish-brown, furrowed, exfoliating bark. The trunk of the trees growing in serried stands, slim, with an openwork crown held high. One of the most common conifers of the northern hemisphere. It grows on sandy and sandy loam soils. It grows in Central Europe, especially in the Alps, South of France, Switzerland, Austria and Bavaria, at altitudes of approximately 6,000 feet, and in the Carpathian Mountains at altitudes of approximately 9,000 feet. It is also found in Northern Russia and Siberia. Also known Siberian pine and Siberian cedar – a tree, for 100-200 years, reaching a height of 20-40 m, with columnar dense crown, with age becoming MNV. The area – Western and Central Siberia. It grows in the forest zone, together with spruce and fir, or forms pure stands – cedar. In the north spread to the forest tundra, mountain forms the border of the forest. Amenity plant. Green wood slightly reddish, but quickly becomes a regular pine color when exposed to air and sun. Universal timber, for all internal and external purposes, for furniture, high-quality architectural purposes and unique, handmade designs. The main feature of pine wood – many solid components. This makes it particularly suitable pine wood for decorative architectural purposes. Although units can be easily processed. It dries very quickly without the risk of deformation or verification. In spite of the high content of resins, varnishes and paints fit well. The volumetric weight of air-dry state: 450 kg / cbm.

Alder

ольхаIt reaches a height of 35 meters and a trunk diameter of 40 – 50 centimeters. Grow throughout Europe, Asia Minor and North Africa. For Russia are important: alder – the largest, most widespread tree with broad, emarginate at the top, shiny dark green leaves; white or gray alder – a small tree, often – a large shrub with smooth bark of the trunk and bluish – or grayish-green leaves, pointed at the top. The sapwood and mature wood a little different: they are light or have a reddish-orange hue. In the middle of the barrel frequent brown patches. Annual rings are mild. Alder wood is no different strength, but has a fairly uniform structure that facilitates the processing. The structure of wood is thin, uniform. It is a little resistant to fungi and pests, but responds well to impregnation. Smooth and thick trunks go to the crafts, joinery and lathe products. Especially appreciated having a very beautiful structure growths (caps) on the trunks of alder. Alder wood is stored under water for a long time, and therefore is used for small underwater structures. The dried alder – one of the most resistant to deformation of rocks. When exposed to light and air darkens alder wood. Before coating with polyurethane varnishes necessary to apply primers, excluding “ignition” of the wood. The volumetric weight of air-dry state: 420 – 640 kg / cbm.

Linden

липаTree up to 30 m, with furrowed dark gray bark and a spreading canopy, diameter 2 (5) m. Sometimes linden (Tilia especially European) live up to 500-1000 years. Basswood grows throughout Europe and in the CIS countries, although it is not planted systematically. In Western Europe, mainly linden planted in parks and is traditional to decorate the tree village squares. The color of the wood can vary from white to yellow, and sometimes red, color development can easily happen when Steaming. Linden is not very durable, if not protected from the environment. Easily machined. It is suitable for surfaces, as varnishes, polishes, etc. N. Release pattern veneer. Veneer is used for a narrow range of products, mainly for painting. Very often a linden tree used for carving. It is also used for the manufacture of matches, pencils and brushes. From the linden obtained excellent charcoal. The volumetric weight of air-dry state: 500 kg / cbm.

Maple

кленNorway maple, or platanovidny – maple tree in the family up to 30 meters high and sometimes up to 1 m in diameter. It grows in North America and Europe in conjunction with other deciduous and coniferous trees. The sapwood and mature wood is almost no difference. Maple wood ordinary white, sometimes with a slightly yellowish tinge, some yellowing with time. The texture is weak. Maple wood – exquisite material for interior decoration, creating a contrast background for dark furniture. It features uniform density and hardness. Wood Canadian sugar maple has irregular grain-layered arrangement of the fibers, why, after sanding and varnishing creates a unique visual effect. By its density in America Sugar Canadian maple earlier replaced the boxwood in the manufacture of boards engraving. If you moisten the sugar maple wood with a solution of ferrous sulfate, it becomes greenish. Maple is prone to cracking, so it requires very careful observance of the drying mode. To prevent cracking prerequisite is drilling holes for nails and screws. We do not recommend the use of paints, adhesives and primers, water-based (possibility of divorce). Before coating with polyurethane varnishes necessary to apply primers, excluding “ignition” of the wood. The volumetric weight of air-dry state: 530 – 650 kg / cbm.

Ash

ясеньA tree from the family of the olive, medium size (up to 35 meters in height). It grows mainly in Europe, although there are American and Japanese varieties of ash. Wood ash is light, slightly yellowish, with a distinct characteristic pattern texture on the cut. The sapwood and mature wood is almost no difference. Ash is harder than oak, but it is very elastic. He responds well to machining. Used for the manufacture of window frames, sports equipment, furniture, including curved, so-called “Viennese” furniture for parquet floors. Wood ash contains toxic substances and can cause some people have allergic reactions. Ash is prone to cracking, so its drying should be done very slowly and carefully. We do not recommend the use of paints, adhesives and primers, water-based (possibility of divorce). Before coating with polyurethane varnishes necessary to apply primers, excluding “ignition” of the wood. The volumetric weight of air-dry condition averaged about 700 kg / cbm.

Oak

дубThe well-known tree from the beech family. It reaches a height of 40 meters and a trunk thickness of 2 – 2.5 meters or more. It features a large variety, it has a total of about 200 species. Widespread in Europe, Asia, North America, North and South Africa. The sapwood of oak wood is light yellow. Mature wood grained, has shades from light-brown to yellowish-brown with a nice texture on the cut. It is strong, durable, resistant to external influences. Over time oak darkens a bit, which gives it a touch of noble antiquity. Oak Wood – an excellent building and ornamental material: she goes to the door and window frames, various buildings and a prussian, furniture, parquet and carpenter timber. It dries rather slowly with rapid drying is prone to cracking. The volumetric weight of air-dry condition averaged about 700 kg / cbm.
