Fire protection measures should aim to prevent a fire starting and to delay the spread of flames and smoke, allowing people and animals to be rescued and fire-fighting to be performed effectively.
The risk of fire developing is totally unconnected with how flammable construction materials are.
In terms of fire protection wood frame construction is without exception viewed positively. When planned and installed with due care the performance of this type of construction in a fire is predictable.
Fire-protective cladding such as fibre-reinforced plasterboard works in combination with efficient comprehensive insulation to virtually prevent any fires developing in cavities.
Robust and stable over long periods
Wood also remains robust and benign in the event of fire as the charcoal layer that forms means that the wood actually burns away relatively slowly (soft wood e.g. 0.7-0.8 mm/min). Residual cross sections heat up only very slowly due to the low thermal conductivity of the wood and therefore retain their load-bearing capabilities for a long period.
Firemen know very well that they can still walk across burnt-down wooden structural elements when steel and concrete have long since failed. Steel wears out through the heat and can fail without warning and reinforced concrete elements can no longer bear loads once the steel rods have weakened in the heat.
