Maharaja Environment Technologies is manufacturer of pine and larch wood in Russia. Thanks to cool Russian climate trees grow slowly what results in prime quality of logs. We are using two types of Russian wood which proved their quality by thousands years of usage: these are Pine and Larch.
According to the doctrine of the tree curative effect pine is considered to be the tree of calmness and courage. Russian Pine is a large coniferous tree standing up to 90-130 feet tall and with a bowl diameter (at the breast height) growing up to 30-50 inches.
According the characteristic of heat protection pine wood exceeds the same indicators of such materials as aluminum and PVC. 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.
Heartwood species are with resin fluxes (concentrated mainly in the latewood). 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 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 to 14. Wood density is medium (from 540 kg/m3 for the wood with natural moisture content). However fiber of Russian Pine is better due to the colder climatic conditions. Dry summers with short vegetative periods induce Russian pine to shade brunches in early stage of bowl development. Thus, lumber recovered of pine logs is less knotty.
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 ashwood and pine. Moreover it almost totally resistant to wood-destroying insects attacks. 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. Larch is the only coniferous tree which wood is related to ironwood on level with oak, beech and walnut. It gets only harder and heavier in course of time. According to the Moscow State University of Forestry researches larch wood is twice more fireproof than 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 (well-known old architectural buildings in Russia) prove that the larch wood can serve for years without application of special antiseptics.
