Ah ha! I knew there had to be more to the story. Looks like a retail/showroom/working dairy. I can see why you went with the higher end building products for that. I've installed a ton of Marvin windows and even been to the Marvin window Factory in Minnesota but Ive never seen them in a barn. It makes more sense now.
We dont use a lot of real butter in our household but when we do it is Kate's. Nothing better with lobster
Someone was just telling me about the company and how they essentially make all their product in a house in Old Orchard. Interesting to put all these pieces together. When will you be open for tours???:licking: I'll bring some freshly baked bread.:thumbsup:
Ive done staple up radiant, quick track radiant, warm board radiant, radiant with crete hete, radiant tied to wire mesh, and electric radiant. I see what you are saying with spray foam and Im sure it works well, I just dont seem how the ecomomics works out in favor. We typically figure that the cost of installed ridid insulation is around $.90-1.00/SF and that is 2" thick. Spray foam is around 1.00/BF and you will need at least two inches. So that works out to twice the cost of spray foam. You would have some slight savings because you probably dont need a separate vapor barrier. Also the irregularity of the surface of spray foam would make it difficult to figure concrete quantity accurately. I dont doubt it works well and If you like it thats all that matters.
I'm guessing you are a mechanical engineer? Did you model the building to get an energy load?
