InfraStop 48" X 125' White Single Bubble Reflective Foil Insulation

I am a big fan of this insulation, I have used it on my walls, under my flooring, and ceiling in my shed/sewing area. I have even used it to make Roman shades, it insulates well keeps cold out, but has been awesome to keep the heat out in my south facing window.Before making my Roman shades I had just cut a piece to fit the window and needed nothing to hold it up on the window. I have made pet beds, floor mats (I get very cold feet) it is awesome stuff. Keep finding new uses for it so, I keep on buying it over and over again. I like the white because the silver side sort of aggravated my nerves a bit. Both work great!
