Further important additional information on the topic of wood protection: What are use classes? Use classes classify wood products according to their change in strength depending on the wood moisture content. Use class 1 - dry area/dry region: The moisture content of the building material corresponds to the ambient temperature at 20 degrees Celsius and a corresponding humidity. This can exceed 65% for a few weeks a year, for example in buildings that are enclosed and heated on all sides. The wood's equilibrium moisture content in NK 1 is 5-15%. Use class 2 - humid area/humid region: If a building material is designated with use class 2, its moisture content corresponds to a temperature of 20 degrees Celsius and a humidity corresponding to the ambient air. This can exceed 85% for a few weeks a year, for example, in roofed, open structures. The wood's equilibrium moisture content is 10-20%. Use class 3: Weathered components For building materials with use class 3, weather conditions are recorded that lead to a higher moisture content than in class 2. These include, for example, structures exposed to the weather. The wood's equilibrium moisture content can be significantly higher than 20%. Durability class: The durability class indicates the classification of the natural durability of a wood. The durability of a particular type of wood depends on its components. Durability classes: 1 – 5 Durability class 1: Very durable – at least 25 years Durability class 2: Durable – approximately 15 to 25 years Durability class 3: Moderately durable – approximately 10 to 15 years Durability class 4: Not very durable – approximately 5 to 10 years Durability class 5: Not durable – approximately less than 5 years dach-holz.tv is the channel with professional tips for roofers and carpenters.
