Gary, are those trailers refrigerated or dry vans? I just curious what sort of insulation they make. I had a customer in Anaheim that I used to service before I retired that did insulation for oil and natural gas pipelines. Their insulation was a mix of two components applied as a spray foam in place. The components of the foam were shipped in refrigerated trailers and trucks because 90 degrees f was the critical temp. If the temperature of the component products reached 90 degrees, it would spontaneously combust with explosive force! The chemicals were in 55 gallon barrels. I was called out there on a hot day in August, and found them hosing down a trailer load of barrels. The reefer had quit working and they said that the chemical was explosive enough to level a few of blocks of the city! They were using the water to keep the temp down around 70 degrees or lower to give them plenty of cushion on the 90 degree critical temp.
