“I’m considering building a large walk-in freezer, approx. 2000 sq. ft. The freezer would be held at 0 degrees Fahrenheit or -18 degrees Celsius. From my research, the walls and ceilings would have to hold an R-value of 32 for those temperatures. Would you recommend using sandwich panels for this project? Or for freezers, is it better to go the traditional way and just install a pre-fab box? Are there sandwich panels with R-values that high? I’m only thinking of using sandwich panels for the walls and ceiling. The concrete floor will be refurbished another way to provide insulation.”
