Wood combustible material and, with steel constructions, wooden components are firstly only suitable under certain conditions for the fastening of fire-tested electrical installations. And wood also be- coming ever more popular sustainable resource and, for environmental reasons, increasingly used in construction (structural engineering). Coatings and panel- ling are also used the constructions, order to achieve fire resistance class all.8 Fastening wooden components In future, ever more buildings will erected with wooden support structures. The combustion rates de- pend the type wood and the moisture content of the wood. With suitable fire protec- tion measures, these buildings not present great- er risk during fire than buildings erected convention- ally.2. The combustion rates are standard means for calculating the re- quired wooden cross-section, depending the de- sired fire resistance class. However, there is fire, wood has very good property: When burn- ing, insulated layer created which delays further combustion.
