3 in. x 24 in. x 96 in. Styrofoam ST-100 Highload-60 Square-Edge Insulation Board, Gray | FMX3.0-60-28SE-DUP

Dupont's 3 in. x 24 in. x 96 in. 3 in. x 24 in. x 96 in. Styrofoam ST-100 Highload-60 Square-Edge Insulation Board, Gray supports efficient installation and long-term durability across commercial and industrial construction settings. The square-edge profile allows for tight seams and uniform coverage, helping maintain a continuous insulation layer. Its lightweight yet durable design simplifies handling and cutting, making it a practical choice for under-slab insulation, foundation walls, and other load-bearing applications where strength and thermal efficiency are critical.

• Highload-60 formulation provides enhanced compressive strength for demanding structural applications
• Closed-cell extruded polystyrene construction delivers consistent thermal performance and moisture resistance
• Square-edge design supports tight seams and efficient installation across flat surfaces
• Suitable for under-slab, foundation, and other load-bearing insulation applications
• Lightweight structure allows for easier handling, cutting, and placement on the jobsite
