Abstract

While building exterior wall insulation systems enhance energy efficiency, fire safety concerns have become increasingly prominent. This paper explores the enhancement of fire resistance in these systems by analyzing the combustion characteristics and fire risks of commonly used insulation materials. Key technologies such as inorganic insulation materials, fire isolation strips, and flame-retardant coatings are highlighted for their crucial role in optimizing fire performance. Through comparative analysis of thermal stability and flame retardancy across different materials and structural designs, a multi-layered fire protection framework is proposed to achieve synergistic improvements in both insulation and fire resistance. The findings provide technical references for architectural safety design and engineering applications.
