How thick is r8 insulation? The insulation is (9/16″ to 5/8″) thick with large single bubble insulation in the center, sandwiched by two thin layers of single bubble insulation. Each roll of insulation includes two rolls of spacer strips. In order to achieve the R-8 value, the spacer strips must be used and placed every 2′ on the ducting.
