Its applications include soil stabilization, road banks, sheathing, below grade applications, insulation, tapered roof insulation, pools and landscaping. The materials also differ slightly in R value, which is the measure of heat flow resistance, aka — thermal insulation effectiveness. Additionally, EPS geofoam price is generally lower in cost which brings higher value when weighing out its durability and effectiveness as a fill material.

The differences ultimately stem from the way they are manufactured, with Styrofoam formed by an extrusion process and EPS form via expansion. The unique formation gives Styrofoam and EPS different attributes. While both Styrofoam and EPS sheets and blocks are often used interchangeably as construction fill and insulation material, there are some big advantages of using EPS in specific situations.

For those looking for a lower-cost insulation material that is more resistant to moisture damage and more durable against harsher external factors like weather and compression, EPS geofoam blocks is the better option.
