This customer in Naples, Florida reached out to us because he was adding air conditioning to hit quonset hut and need to help keep it cool. Quonset huts are made out of metal and as many South Floridians with metal buildings know, an uninsulated metal building can get roasting hot! We applied 3" R20 closed cell spray foam to the upper part of the roof and 2" R13 closed cell spray foam to the upper part of the walls to eliminate the radiant heat and to allow the A/C to actually do it's work efficiently. If you have a Quonset hut and are interested in making it cooler, contact us today to see how we can help!
