Fires in buildings pose significant risks to property and human lives, making material selection crucial for fire safety. This study evaluates the fire reaction of wood agglomerate boards, both treated and untreated, under controlled heat exposure. The tested boards include untreated wood chipboard, chipboard with varnish, intumescent paint, Formica coating, and a fire retardant chipboard (Fimapan IGN E-Z-Finsa). Results indicate notable differences in weight loss and carbonization, with varnished chipboard performing the worst. Intumescent paint proved highly effective, forming a protective char layer that extended ignition time and reduced material degradation. The Electric Radiator test provided valuable insights into the combustion characteristics of these materials. Applying fire retardants, especially intumescent paint, markedly enhances the fire reaction properties of wood agglomerates, bolstering their safety in construction. This study underscores the critical role of material selection in fire safety and provides valuable data for developing more fire-resistant building materials.
