Facts About XPS

To ensure peak efficiency and endurance for our walk-in coolers and walk-in freezers, Amerikooler uses only the highest quality insulation in our panels, incorporating ultra premium foam insulation (manufactured by Dow Chemical Company) into each of our panels. This superior insulation not only meets, but exceeds U.S. Federal requirements with R-29 for coolers and R-32 for freezers.  It also provides enhanced energy efficiency and features other prominent benefits, including:

  • Hydrophobic properties, so moisture will not deteriorate the R-value.
  • A dense, consistent closed-cell structure.
  • Exceeds federal requirements from the US Energy Independence Act of 2007 (EISA).
  • No voids or pinholes that allow thermal conductivity.
  • Production with precise control over density and cell size and orientation.
  • Environmentally-friendly construction.
  • An unprecedented 50-year thermal warranty.
  • The ability to lower your energy costs for years to come.


Show No Weakness

The proprietary extrusion process used to produce Amerikooler’s insulation provides precise control of compressive strength, cell density, size and orientation to ensure uniform composition for uniform performance. While the polyurethane panels some of our competitors use can often suffer from bubbles and voids during the expansion process (compromising the integrity of the walk-in cooler), the AK-XPS insulation used on Amerikooler products do not suffer these defects and ensure that panel integrity remains strong. Amerikooler products, unlike hard-nose manufacturers, do not contain low R-value materials like wood or high-density urethane along the perimeters that allow for thermal movement.

Keep Dry, Keep Kool

Walk-in freezers and coolers should provide lasting efficiency. Amerikooler’s AK-XPS™ insulation contains strong hydrophobic properties to prevent water absorption, ensuring that moisture present in low-temperature situations is not absorbed into panels. Since extruded polystyrene’s R-values decrease at a much slower rate, there is less thermal conductivity and less energy consumption. The lower power bills are just a perk of the peak efficiency and quality of our products.

Guaranteed Value

Our AK-XPS insulation is so effective that we offer Dow’s 50-year thermal warranty to back up our promise of lasting efficiency. No other polyurethane insulation is backed by this assurance!
