Today, the use of timber and steel frame structures is increasing rapidly. However, fire safety in these building types is one of the most important topics in the design process. Fire-resistant partition wall systems help preserve life safety by delaying the spread of fire within the building. A1 class non-combustible boards and mineral wool infill materials used in timber frame systems are tested and certified to provide fire resistance for specific periods. Similarly, high-performance fire protection boards used in steel construction systems provide resistance up to EI 120 levels, enhancing the fire performance of buildings. The use of these systems is particularly important in critical areas such as technical spaces, shafts, escape corridors and fire compartments. Firesol contributes to the creation of safe and sustainable buildings by offering internationally compliant fire compartmentation solutions in timber and steel construction projects.
