The moisture content of wood varies with the humidity (not to mention the direct hit of water, such as rain). In case of fluctuations of relative humidity, wood seeks to balance the moisture, ie, it dries out, losing moisture and expands (swells) when wet. This can lead to significant warping of wooden structures and products, so it is essential to reduce the inherent timber capacity for water absorption.

But the main enemies of the tree are different microorganisms (molds, algae, bacteria, fungi and antimitsety), insects and, of course, fire. Protection of wooden materials from these harmful external influences – a serious problem.
