Still looking to buy a small floral walk-in.
My big hang-up is what insulation is better:
Polystyrene (styrofoam) or Polyurethane foam?
I have read that polyurethane has been recommmended often, but also that liquid can permeate urethane - something very undesirable.
Why are most cheap coffee cups made of styrofoam, not polyurethane? Is it because urethane is too costly or is it because it cannot contain/hold water?
I'm looking at SRC Refrigeration out of Michigan who uses polystyrene and Bush Refrigeration out of New Jersey who champions polyurethane.
