Some properties of Russian coniferous trees wood

дом из лиственницы, оцилиндрованное бревно, дома  из оцилиндрованного бревна, профилированный брус, срубы  из оцилиндрованного бревнаNorthern latitude trees grow very slow during short summer only. So, tree rings are very thin hardly exceeding 1 mm while fibers bear against each other. This explains the wood high firmness. Northern wood logs last longer and are resistant to deformations, humidity influence and temperature drop. Moreover, this type of wood is very attractive to look at.

 

Pine (pinus sylvestris)

лафет лиственница, коттедж  из профилированного бруса, проекты  из оцилиндрованного бревна, брус оцилиндрованный, бани  из оцилиндрованного бревнаAccording to the doctrine of the tree curative effect pine is considered to be the tree of calmness and courage. Pine wood is mechanically reliable, fabricable, with low heat conductivity. Pine wood has bright distinctive texture pattern. It neither fades nor bleaches while becoming darker and acquiring reddish tinge due to large amount of resins over the years.

Wide sap wood is from yellowish to pink in colour. Rings are well seen in all the sections with clear border between early and late wood. Wood rays are not seen.

Pine from Russian northern regions (the Arkhangelsk Region and Karelia) possess the best properties. It has narrow-ringed dense wood with high amount of late zones as well as narrow sap wood. Rings amount in 1st centimeter is 10 to14. Wood density is medium (from 540 kg/m3 for the wood with natural moisture content).

European fir-tree (picea abies)

пиломатериал еловый обрезной, оцилиндрованное бревно продажа, брус профилированный цена, производство оцилиндрованного бревна, оцилиндрованное бревно купить, производство профилированного брусаFir-tree - non heartwood exploitable species which has low amount of resin fluxes. The wood is regular, of white color with yellowish or sometimes pink tinge. Rings are well seen in all the sections; late wood is darker than the early one. Wood rays are not visible. As opposed to the pine larger snubs are situated in nodes between which single snubs of smaller sizes can be met.

The wood is less fabricable because of the majority of snubs and their hardness.
Merits: regular structure, long fibers, stable white color, low resinousness.

The fir-tree does not turn blue for a long time; that is why fir tree of natural moisture content can be transported and kept for long.

Larch (siberian larch)

дом из лиственницы, строительство  из профилированного бруса, дома  из оцилиндрованного бревна цены, проекты бань  из оцилиндрованного бревна, строительство домов  из профилированного бруса, изготовление оцилиндрованного бревна Siberian larch is the only penaceous kind of coniferous tree with needles falling off in winter.

The unique larch wood is world famous for its usage in the Venice construction. Experts say that some Russian houses and churches will exist more than 800 years. «Tree of eternity». Premium class product.

European standard relates larch to the group of extra firm species of wood. Relative biological stability (fungus and insects degradability) of the wood is twice higher than that of the pine.

Apart from its peculiar firmness and resistance to environmental conditions larch is characterized by good color and perfect structure.

Larch wood considered to be the best in relation to its resistance to atmospheric conditions. Long-term researches have shown that combination of high density and resinousness (with its specific structure) makes larch being the most decay resistant wood as well as twice firmer than oak, ashwood and pine. Moreover it almost totally resistant to wood-destroying insects attacks.

Larch is the only coniferous tree which wood is related to ironwood on level with oak, beech and walnut. Brinnel Hardness is 3.2 (oak, beech-3.9, pine - less than 2). It gets only harder and heavier in course of time.

Larch is related to the wood which is high resistant to decay due to high tannins content. So it can be used without any chemical treatment in those cases where other species are liable to stain and decay. Larch excels the oak in these qualities.

According to the Moscow State University of Forestry researches larch wood is twice more fireproof that that the pine wood.

Larch color grade increases architects' and designers' possibilities greatly. Its rings are well expressed and seen.

The parquet of the Ostankino Earl Sheremetev's Palace and window frames of Zimny Palace prove that the larch wood can serve for years without application of special antiseptics.
