Rigid foam board is widely used in residential construction, commercial buildings, and industrial insulation systems. In building envelopes, rigid foam boards are commonly installed on exterior walls, roofs, basements, and foundations to improve thermal efficiency and reduce energy consumption. The material is also used in prefabricated wall panels, structural insulated panels (SIPs), and cold storage sandwich panels. Because rigid foam board provides both insulation performance and dimensional stability, it is suitable for applications where continuous insulation layers are required to minimize thermal bridging. Additionally, many refrigeration and cold chain logistics facilities rely on rigid foam boards to maintain consistent internal temperatures.
