Is bubble insulation as good as rigid foam?
I am having a home built. I want to install insulation on the outside of the home. I live in Southern Illinois, which according to BuildingScience.com is a mixed-humid location like Louisville, Kentucky.
I was planning to have 0.5 inch rigid foam insulation installed, but my framer stated he can get bubble insulation. He said he normally installs this under metal roofs, but it would be as good as R value wise as 0.5 inch rigid foam. Is this true? Are there any issues with using it as an outside wall insulation method? The walls are OSB with house wrap, and we will have vinyl siding.
