PIR Roof Panels
First-class thermal insulation and energy efficiency
The PIR roofing panel is filled with polyisocyanurate foam—a material boasting exceptional thermal insulation properties. With a low thermal conductivity of just 0.021 W/(m·K), it creates a robust thermal barrier on the roof. In summer, it prevents solar radiation and external heat from entering the building, reducing air-conditioning energy consumption; in winter, it effectively retains indoor heat, minimizing heating costs. This outstanding insulation performance helps maintain a stable indoor temperature and lowers users’ long-term electricity expenses.
Excellent fire resistance and high strength
The PIR roofing panel boasts exceptional fire‑protective properties. Its PIR foam core is inherently flame‑retardant and meets the stringent B1 fire‑resistance standard. When exposed to flame, it is less readily ignited, and during combustion it produces minimal smoke and toxic gases, providing critical protection for buildings. At the same time, the panel is reinforced with high‑quality metal facings—such as color‑coated steel sheets—giving it superior load‑bearing capacity. It can maintain its structural integrity and stability even in harsh weather conditions.
Simple installation and time savings
PIR sandwich panels are manufactured in a factory and assembled on-site. The panels are precisely sized and easy to install, allowing for rapid construction of the enclosure system and significantly shortening the construction cycle. Their scientifically designed tongue-and-groove joints ensure a tight connection, reducing installation errors while maintaining excellent insulation, sealing, and structural stability. The lightweight panels are easy to transport and hoist, effectively reducing labor costs and construction difficulty, and helping projects to be put into use faster. They are an ideal choice for the efficient construction of cold storage facilities, warehouses, industrial plants, logistics centers, and cleanroom projects.
