Choosing Between EPS and XPS Rigid Insulation Thermaboards

A number of studies show that EPS retains less moisture than XPS. A case in point is a side-by-side analysis of the two rigid foam types installed on a commercial building foundation. When extracted and tested after 15 years in service, the EPS had 4.8% moisture content by volume, compared to 18.9% for the XPS (a four-fold difference).

Comparing EPS Insulation and XPS Insulation - Which is Better?

The higher the density of the product, then the higher the R-value will be. When you compare EPS and XPS insulation at the same R-values, EPS insulation can be between 10 to 30 percent less expensive and costs about 19 cents per sq. ft. for a single, 1-inch 4×8 sheet.

EPS vs. XPS: You Be The Judge : Plymouth Foam

Jun 05, 2014  EPS (expanded) and XPS (extruded) are both closed-cell rigid insulation made from the same base polystyrene resins and manufactured differently, EPS is beads that are molded or cut into various sizes and shapes while XPS is extruded sheets. During manufacturing, EPS’s blowing agent leaves the beads rather quickly creating thousands of tiny ...

Apr 06, 2020  Apr 06, 2020  When building a slab on grade, EPS rigid foam insulation is the most common choice of insulation, for performance and cost. I wouldn’t go as far as saying you 'couldn't' use spray foam below a slab, but I’m not sure why you’d want to. Spray foam for sure has uses where it is the best choice by a long shot, but under a slab is not the place.
