EPS Foam Sheets for Insulation, Construction & Packaging

Our expanded polystyrene (EPS) foam sheets are available in full 4 ft by 4 ft by 8 ft blocks and can be custom cut to meet your exact specifications. Lightweight yet durable, EPS is ideal for packaging, construction, insulation, signage, and custom fabrication projects. EPS foam sheets are also widely used for walk-in coolers and freezers, floor leveling, and sound deadening applications. For larger material needs, explore our foam billets, or view our custom foam displays for large-scale projects.

• Lightweight and easy to handle for construction and packaging applications
• Excellent insulation properties for buildings, walk-in coolers, and freezers
• Custom cut EPS foam sheets to any size, shape, or specification
• Durable and cost-effective rigid foam material for large-scale use
• Ideal for signage, molding, fabrication, floor leveling, and sound deadening

EPS foam sheets are manufactured by expanding polystyrene beads into a rigid, closed-cell structure that provides strength while remaining lightweight. The material can be cut, shaped, and molded with precision, making it highly versatile across industries including construction, insulation, packaging, and custom fabrication.

Density	Material Type	Tensile Strength	R-Value (per inch)	Best For
1 lb EPS	Lightweight	Lower strength	~3.6 – 3.8	Void fill, flotation, lightweight applications
2 lb EPS	Standard-duty	Moderate strength	~4.0	Construction, packaging, concrete replacement
2.5 lb EPS	High strength	Higher strength	~4.2	Structural applications, heavier loads
3 lb EPS	High-density	Highest strength	~4.4 – 4.6	High-load, demanding structural support
