Polyisocyanurate (PIR) Sandwich Panel is a building component with modified polyisocyanurate foam as the core material. By tightly bonding the core to metal facings, it enhances air-tightness and water-tightness at joints, effectively preventing thermal b
Roofing Product Series: Huaneng™ Polyisocyanurate (PIR) Metal Sandwich Roofing Panels.
Polyisocyanurate (PIR) metal sandwich roofing panels use modified isocyanurate (PIR) as the core material, tightly bonding the core material to the metal panel. This improves the airtightness and watertightness of the joints, effectively preventing thermal bridging and creating a waterproof, convenient, and aesthetically pleasing integrated building roofing panel.
After molding, the panels have high strength, heat insulation and energy saving characteristics, and fire resistance up to B1 level, providing an excellent choice for building roofing systems with high insulation requirements.
Product Performance Characteristics
High Efficiency and Energy Saving: Excellent thermal insulation performance reduces building energy consumption.
Good Fire Resistance: Thermosetting insulation material, no flame spread.
Strong and Durable: High board strength and superior mechanical properties.
High-Crest Design: Improves board surface load-bearing capacity while also balancing water flow.
Watertightness/Airtightness: Polyurethane has good water repellency, and the interlocking structure of the boards ensures good airtightness.
Selection Table for Performance and Thermal Properties of Polyisocyanurate (PIR) Metal Sandwich Roofing Panels
This table is based on a PIR density of 40 kg/m², an outer steel plate thickness of 0.6 mm, and an inner steel plate thickness of 0.5 mm. For more parameters, please consult our engineers.
