Thermocol (Expanded Polystyrene – EPS) and Polyurethane Foam (PUF) are widely used thermal insulation materials. Thermocol is lightweight, affordable, moisture-resistant, and ideal for construction/packaging. PUF offers superior thermal resistance (higher R-value), greater durability, and structural strength, making it better for long-term cold storage and demanding industrial applications. Thermocol Insulation is a white, cellular plastic foam composed of small, trapped-air polystyrene beads. PUF Insulation is a high-performance rigid foam material created by mixing chemicals, usually produced in sheets or panels.
