The word Styrofoam™ is often used to describe expanded polystyrene (EPS) foam; however, ‘Styrofoam’ is actually a trademarked term for closed-cell extruded polystyrene foam made for thermal insulation and craft applications. EPS foam is the correct term for any form of expanded polystyrene.

Expanded Polystyrene insulation is lightweight, rigid, closed cell insulation. EPS is available in several compressive strengths to withstand load and back-fill forces. This closed-cell structure provides minimal water absorption and low vapor permanence.

Commonly used as insulation for walls, foundations and roofing, there are many benefits to selecting EPS products:

• Long-term R-Value (“R” is the resistance to heat flow)
• Energy efficiency
• Constant thermal resistance
• Measurable energy savings
• Strength

• Sustainability
• No growth of bacteria, nor will it decay over time
• Dimensional stability
• Chemical inertness
• Low cost

A cost efficient, high performing alternative to extruded (XPS) foam, EPS is the perfect choice for many insulation and construction applications.
