8 Fastening wooden components In future, ever more buildings will erected with wooden support structures. The combustion rates are standard means for calculating the re- quired wooden cross-section, depending the de- sired fire resistance class. Coatings and panel- ling are also used the constructions, order to achieve fire resistance class all. However, there is fire, wood has very good property: When burn- ing, insulated layer created which delays further combustion. The combustion rates de- pend the type wood and the moisture content of the wood. And wood also be- coming ever more popular sustainable resource and, for environmental reasons, increasingly used in construction (structural engineering).

With suitable fire protec- tion measures, these buildings not present great- er risk during fire than buildings erected convention- ally. Wood combustible material and, with steel constructions, wooden components are firstly only suitable under certain conditions for the fastening of fire-tested electrical installations
