High-density and durability
It is provided by higher density of Northern wood due to low growth rates of Northern trees in cold summer, lack of growth but strengthening in density during the rest time of the year
Due to lower temperatures, the Northern trees are extremely rarely infected with bugs, whose vital activity leads to loss of wood strength
Low humidity and high humidity resistance
It is caused by low circulation of moisture in the trunk of the northern tree due to its higher density. As a result, the northern tree is characterized by lower moisture absorption than the trees of more southern latitudes.
High microbiological stability
It is provided by high resin content in the trunk which prevents wood from rotting and increase wood durability, long periods of use of materials produced on its basis
