for the protection of the flame retardants used materialv wood choice depends on the diameter of the log desires and financial capabilities of the customer, the climatic conditions and seasonality of operating at home, as well as the requirements for the external aesthetics of log houses. In addition to the thickness of the logs, another important indicator of the aesthetic to the use of timber is its knotty. In pine at the bottom of the barrel there is little knots, so the most expensive, but better quality, is the so-called butt saw cut – the bottom 6-8 m of the trunk.

Some customers refuse to outposts logs for this characteristic of color and to avoid damage to the fibrous structure of the tree.
