rotfasthet
Rotfasthet is a term used in timber science and building to describe a material's resistance to rot, i.e., decay caused by wood-destroying fungi and other organisms. It encompasses natural durability and the effectiveness of protective measures, determining whether timber can withstand exposure to moisture, soil contact, and outdoor conditions without significant loss of strength or integrity. In practice, rotfasthet is a key criterion when selecting wood for exterior applications and for design and maintenance planning.
Natural durability varies widely among wood species. Heartwood often contains extractives that inhibit fungal growth, giving
Moisture, temperature, oxygen availability, and nutrient access strongly influence rotfasthet. Fungi require relatively high moisture content
Enhancing rotfasthet can involve selecting naturally durable species, applying chemical preservatives through pressure treatment, or employing
Rotfasthet remains a central consideration in timber construction, influencing material choice, treatment strategies, and long-term performance.
