What's the Difference between EPS (Expanded Polystyrene) and Polyurethane Panels?

Polyurethane Compared to EPS Panels

Our Polyurethane panels may look like other insulated cool room panels, but looks don’t tell the entire story. Many panel systems use Expanded Polystyrene (EPS), a product that’s been in use for over 50 years. EPS has an R-Value of 3.5 to 4.0 per inch.

Our panels use Polyurethane, which was invented to improve upon the shortfalls of EPS. Polyurethane has an R-Value of 7.0 to 7.5 per inch, making it the world’s highest-rated insulation per inch, which explains why it’s the choice of manufacturers of everything from freezers to water coolers to refrigerated semi-trailers.

Better Fire Resistance

EPS can be damaged by temperatures over 180 degrees, so it offers little fire resistance. Class I rated polyurethane—the kind we use—can withstand temperatures of 750 degrees without damage. At those temperatures, it chars but does not burn, so it minimizes the spread of fire. In fact, the material normally self-extinguishes.

Greater Density For Greater Strength

At a minimum density of 2.2 pounds, our panels are more than twice as dense as EPS, which provides greater strength.

Less Environmental Impact

Typically, EPS panels are created in standard sizes and cut at the job site to fit your room requirements. The scraps usually cannot be recycled. In comparison, our cool rooms are designed and hand made to your specific plans, so waste is minimal.

The polyurethane we use acts as its own adhesive, for a strong, consistent bond across the entire panel. EPS manufacturers have to use separate glues, with the quality of the bond dependent on how evenly the glue is spread and how long it dries.
