CI Max® Foam Continuous Insulation

Johns Manville CI Max is a high-efficiency rigid foam sheathing designed for exposed interior applications. It is composed of a uniform closed-cell polyisocyanurate foam core bonded to a glass-mat reinforced 1.5-mil embossed aluminum facer that is meant to be left exposed. Available in a white or silver finish, CI Max is approved for use without a thermal barrier and provides an attractive, durable interior finish.

CI Max is suitable for wall or ceiling applications in residential, commercial, agricultural, and industrial buildings. It provides a continuous layer of insulation that reduces thermal bridging and improves energy efficiency. Maintaining a minimum thickness of one inch, it qualifies as a Class I vapor retarder. CI Max is produced with an EPA-compliant hydrocarbon blowing agent with zero ODP and virtually no GWP.
