If you are wondering just how much more efficient Extruded Polystyrene is than Polyurethane in a walk-in freezer, complete the dimensions of your walk-in below.

This calculator estimates the energy savings consumers see over time from their Extruded Polystyrene walk-in unit compared to a Polyurethane walk-in unit. This is just an approximation and estimates many significant factors such as refrigeration, ambient temperature, etc.

You can save thousands of dollars with extruded polystyrene insulation vs. traditional foam-in-place polyurethane. For a full explanation of why extruded polystyrene is superior to foam in place, see Insulation Brochure (pdf) and Owens Corning Case Study (pdf).
