Why Choose EPS?
Bacteria and mold resistant
Resistant to aging
High compression strength/ft2
What is EPS?
Expanded polystyrene (EPS) is a innovative, versatile cellular plastic material made of small hollow polystyrene beads and air – not greenhouse gases like its competitor. It is this closed cellular construction that gives EPS its noteworthy characteristics making it an excellent choice for eco-friendly construction, packing and creative materials.
Innovation Building provides EPS in many forms.

Is EPS Styrofoam?
No, EPS (expanded polystyrene) is made by expanding polystyrene beads with air. Styrofoam is actually extruded polystryrene (often called blue sheets) and is made using chemical blowing agents such as harmful chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs). EPS is available in various shapes, sizes and densities and is generally more cost effective than Styrofoam (XPS).
How does the R-value of EPS compare with other insulation?
EPS is filled with air and thus the R-value of EPS is stable and will not change over the life span of the building. Other insulation materials use chemical blowing agents that have a high resistance to heat resulting in high initial R-values. But similar to a helium balloon, these gases will diffuse out over time reducing the R-value. Some test have shown that the insulation value of these products can reduce as much as 30%. EPS does not use these types of blowing agents, therefore, its insulation performance remains stable over its entire life resulting in a better long term R-value.
Is EPS moisture resistant?
EPS is a closed-cell structure and thus non-hygroscopic so it does not take-up or retain moisture. It is mold and fungi resistant. EPS is often used for boat docks, marinas, boathouses, and piers.
Is EPS cheaper than other insulation materials?
The R-value of EPS will not reduce over time like other thermal insulation materials making EPS one of the most cost-effective insulation materials available.
Can EPS act as a vapor barrier?
EPS has a low water vapor transmission rate, but EPS is not a vapor barrier. EPS "breathes", and therefore does not require expensive venting as do other insulation materials, which trap moisture within walls and roof assemblies.
