FTC underslab insulation issues

Unknown

Because there is currently no test to determine the R value of reflective material the FTC can only consider thickness as the determining factor which is how they come up with R-2. According to Insulation Solutions' tests, which were done under a slab with a mean temp of 65*, they claim to have achieved R-7.54. They went on to say that the FTC required a mean temp of 75* which reduces that R value to 6.83 and this is where the issue lies. They continue to stand by their product based on it's actual performance and claim there have been no incidents where a job failed because the product did not perform to specs. They were supposed to email me documentation but that has not happened as of yet. As I've stated in other posts, I do use the product and have had acceptable results with it. When I present it to the customer I also present the option of the styrofoam board and explain the differences, pros/cons of each etc but thus far all my customers have chosen the tarp.
