Foam sheathing like Neopor® and Neopor® BMB can be installed as continuous insulation. Continuous insulation is “insulation that runs continuously over structural members ( thus significantly reducing the effects of thermal bridging) and is free of significant thermal bridging; such as rigid foam insulation above the ceiling deck. It is installed on the interior, exterior, or is integral to any opaque surface of the building envelope” (Office of Energy Efficiency and Renewable Energy).
Did you know, depending on the type of studs used in framing between 15% - 50% of energy loss can be caused by the effects of Thermal bridging? (Fundamentals of Thermal Bridging)
According to the Foam Sheathing Committee of the American Chemistry Council, continuous insulation is “more effective than cavity insulation because it is not thermally bridged by framing members” (Foam Plastic Applications for Better Building). Recent energy codes, including the 2024 International Energy Conservation Code (IECC) and ASHRAE 90.1-2022, have prescriptive requirements for continuous insulation (ci) in essentially all of the climate zones in the United States (Building Thermal Envelope 101).
