I always wondered how they made those giant refrigerated warehouses for beef or poultry processing. I guess it makes sense that they would use polyurethane foam–I wonder if the same type of thing is used in normal every day refrigerators? One thing the article doesn’t mention at all is the cost or alternatives. I wonder if there’s viable alternatives to polyurethane foam for insulation. From the way the article sounds SPF foam must be the standard? Or is it, I just wonder. Reply
I am working on cold storages for sea food to vegitable. Do not understand why your item is not available in Bangladesh. There are good demand and the price proposed if it is accepatable for food grade insulation than I am willing to import and sell to local cold store builder. it is also suitable for the top floor of growing apartment building where it is too hot in summer. Our building are cement concrete and M>S Rod and sand brick made one.Not wooden buildings as shown in your video. Looking forward to hear more. Reply
Spray foam production requires expertise and very expensive equipment. You must find a local contractor. We are thousands of miles away, and unfortunately, unable to help. Reply
I always wondered how they refridgerated things large scale. I have never heard much about refrigerated warehouses before. Reply
