Protection of structural timber is a set of actions aimed at protecting wooden elements against biological (fungi, mould, insects), physical (moisture, fire) and mechanical (damage during transport and installation) factors.
Adequate timber protection is crucial for the durability of the structure and the safety of the building. Chamber-dried and four-sided planed timber is primarily used in timber frame construction. This reduces its moisture content and makes it less susceptible to biological corrosion. In addition, the wood can be impregnated with chemicals - pressure or surface treatment - to increase resistance to external agents.
Protecting structural timber also includes proper storage and installation. The timber must not be exposed to prolonged moisture or contact with the ground. In some cases, the following is also applied fireproofing, e.g. fire retardant impregnations or special panels in the interior.
