Fire resistance of timber structures This refers to the ability of wooden components to retain their load-bearing capacity and stability during a fire. Contrary to popular belief, wood does not immediately lose its properties when exposed to high temperatures. During combustion, a charred layer forms on the surface of the wood, which partially protects the deeper parts of the structure. As a result, the loss of load-bearing capacity occurs more slowly and predictably than with some other materials. Designers take the rate of charring into account as early as the structural calculation stage.
Carefully selected cross-sections ensure that the required strength is maintained for a specified duration of a fire. Fire resistance is also influenced by the type of wood, the moisture content of the material and the protective measures applied. Timber structures They often use additional fire-resistant cladding, which extends the fire resistance of the entire system. Thanks to modern solutions, timber can meet stringent fire safety requirements even in larger buildings.
