Insulation - Rigid Board
Dow - Rigid Foam Insulation
Dow Rigid Foam Insulation replaces non-insulating above-grade sheathing products like plywood, fiberboard and OSB, and eliminates the need for additional air barriers such as housewrap.
Johns Manville foam boards are used as insulation/nailbase underlayment for a variety of roofing systems and sidewall applications.
For installation convenience and exceptional, long-term performance, the all-in-one ZIP SystemŽ R-Sheathing panel provides a new approach to sealing and insulating the building envelope. One panel delivers thermal, air and moisture resistance, while providing excellent strength and durability.
