Antiseptic
Antiseptic treatment is the application of a special antiseptic to the surface of the wood to protect it from a wide range of physical and biological agents. As early as ancient Egypt, exceptionally valuable wood products were impregnated with cedar oil to preserve their appearance and properties for longer.
For many centuries, wood preservatives such as wood tars and charcoal have been used to impregnate industrial wood. Today, the choice of wood preservatives is much wider and ranges from natural oils to specially formulated materials.
Fire retardant
Fire retardant is the application of a special fire retardant solution (fire retardant) to wood to reduce the flammability of wooden structures. Fire-resistant wood products are the basis for responsible building. This is because the chemical preservatives used in wood slow down the oxidation process that occurs when wood burns. As a result, the wood burns more slowly, emits fewer burning particles and produces less smoke, which has many benefits. In particular, more time can be spent safely evacuating the building. In addition, as the fire will spread more slowly than with untreated wood, the fire can be stopped more quickly. The likelihood of significant damage is then reduced.
