Insulation Foam Core and structural Foam Core differ primarily in mechanical capability and intended use. Insulation Foam Core focuses on thermal resistance and moisture control, often with low density and limited load-bearing capacity. Structural Foam Core, on the other hand, is engineered to carry mechanical loads and resist shear and compression. Structural Foam Core undergoes more rigorous testing and quality control to ensure consistent mechanical performance. While insulation Foam Core may be sufficient for non-load-bearing applications, structural Foam Core is required for composite sandwich panels subjected to bending, impact, or dynamic loads. Understanding this distinction is essential to avoid underperforming or unsafe designs.
