Can one use cavity insulation in conjunction with continuous on ceiling and or walls?
Yes, insulation to be installed between furring or studs is entered in the Cavity R-Value column. If the installed wall insulation will be continuous (such as with exterior rigid insulation or interior “draped” insulation), the insulation R-value is entered in the Continuous R-Value column. A combination of insulation systems may be used. For example, installing R-13 batt insulation between the studs and R-5 rigid insulation on the exterior of the stud wall. Cavity insulation is insulation installed in the cavities between structural members, such as wood studs, metal framing, and Z-clips. Continuous insulation runs continuously over structural members and is typically rigid foam board. Cavity insulation is affected by thermal bridging, while continuous insulation reduces thermal bridges.
