Influence of Properties of Building Materials in Wooden Sandwich Constructions on Overall Fire Resistance

By choosing suitable individual building materials for a sandwich structure, we can ensure an increase in the fire resistance of the entire structure. The influence of the properties of individual building materials on the overall fire resistance in sandwich constructions has not been well researched. It is for this reason that we focus our contribution on the influence of the properties of building materials in wooden sandwich structures on overall fire resistance. In the wooden sandwich constructions we created, we worked with reference constructions composed of thermal insulation with different surface treatments and with constructions that have the same thermal insulation, but we added 40 mm thick mineral wool to them. Subsequently, we tested the structures according to the EN 1365-1 standard [4]. After processing the obtained results, we came to conclusions about the effect of mineral wool and its combination with suitable thermal insulation on overall fire resistance.
