Only 1/2-inch thick though. Good catch... I could see cutting it into 4 6" by 50' rolls and wrapping a riser with it like fiberglass pipe insulation... I couldn't understand their listed R value ratings and how they relate to thickness and density (cf6 @ 6lbs/cubic foot, and cf8 @ 8 lbs/cubic foot)... I think they are not listing the R values correctly for all thicknesses and weights. I am assuming like fiberglass insulation, more density = higher insulative value... And thus CF8 should perform better at the same thickness. Can anyone confirm this is correct or backwards? |
