Before insulating your basement, ensure proper waterproofing if needed, as InSoFast panels are not a waterproofing solution. Our panels come in two thicknesses—2” (R-8.5) and 2.5” (R-10.5)—and can be combined with rigid foam for an R-value up to 21. Installation is simple with basic tools, and our website offers videos, articles, and sample kits to help you get started.
