I really do not know if Nasa had anything to do with this insulation, but it is definitely a space age product. I actually stumbled up on this product building a hot rod. My son and I were building a 32 Ford coupe and needed something to insulate it with for heat. We decided to use this product and installed it between the roof of the car and headliner ( and everywhere else we could). While attending the street rod nationals in Louisville Kentucky in August, hot asphalt, not a tree in sight, 95 + degrees Fahrenheit, I knew we made a good choice. The hot rod is black and you could barely stand to reach out the window and touch the roof, but inside next to the insulation (we did not have a head liner in yet) it was barely warm.
After that experience I began using the insulation for it’s intended purpose which is housing. The other post frame house we built we used this product exclusively in the walls as well as under the metal roof. Also if you look at the pics (hopefully) you can tell we added another layer on the interior walls. This will give us a 1 1/2 inch air space, a layer of insulation, another 1 1/2 inch air space, a final layer of insulation between the wood and the metal on the exterior of the building. This has proved effective in my son’s house. It also allows not to build thick walls and use less lumber. If the advertisements are correct we should have slightly less than an R-30 in the walls (R-13 is the code requirement around here). You lose some of the R-factor when you do not have an air space on each side of the insulation. We have one layer sandwiched between the metal and the wood.
There is a link to the company that sells this insulation in the right column under construction materials.
