Wood is a unique material with respect to fire. Despite being combustible, it is a stable structural element when confronted with flame due to its low thermal conductivity and characteristics of its chemical degradation (Pyrolysis). The level of fire resistance is determined by the mass, size, and configuration of the constructive elements used.<\/p>\n

When wood is used as a cladding material, takes the form of boards, plates, or other thin strips, therefore its behavior is subject to its combustibility. This risk is why building fire-safety codes and regulations in many countries have been increasingly restricting the use of combustible claddings.<\/p>\n

In this study we used modeling techniques and computer fire simulations to evaluate the influence of facade configuration on fire trajectory and the level of protection it can offer at the facade surfaces.<\/p>\n
