..........Actually, Poly Eurethane is made by mixing Polyol and Isocyanruate together under high pressure so it is the same thing.
The reason I ask is I have worked in the Poly Eurethane manufacturing industry off and on since 1981. When I built the addition on my mobile home I salvaged garbage bag test shots from the factory I worked at, sawed them in slabs about 3 inchs thick and just a 1/4 inch wider than the stud openings and stuffed the pieces in the studs and the rafters. You wouldn't believe how snug and cozy this made the home. I installed a wood burner in the new addition and until about 2000, I never burned more than a full cord of wood in my stove. This was the only source of heat we had in a total of 1500 square feet of house here in West Tenn.
Then in 2000, I decided to install a central heat and air system but we still use the wood. Now I fill my 10 x 10 woodshed almost full and have 2 years supply of fuel to burn.
I was wondering if anybody had used it and if there were any issues. Like mentioned, flexability, or glue. As far as the foil, I would think you could remove it. Just be careful about getting rid of the scraps. Don't burn them because the Iso side of the chemicals puts out a fume that shuts off the air supply. It is fire retardant, but not fire proof usually.
By the way, that 1 1/2 inch that Bruce put in the roof would equal an R value of about 10.5. That is very close to 3 inches of fiberglass bats.

Dave I'm using the Insulated Steel door cupons from french door cutouts at home and building both trailers. It insulates great at home and in the trailers. The door blanks are 1 5/8" thick x 20" wide x 80" long. It was a great find for me. They even make Summer cottages entirly out of this stuff; leaving the steel clad in the cupons and scarfing the edges and using "Gorilla Glue" and selftapping sheet metal screws for fasteners. They claim the doors are an R-19 value. I have Three layer in my attic which is fantastic ( insulation and a floor at the same time ).
