Announcing ProtectoR™ HD

DSC_4066.jpg

Johns Manville introduced high-density polyiso cover boards to the market over ten years ago with Invinsa®.  Building off the proven success of that original innovation, Johns Manville is proud to announce ProtectoR HD, a ½” thick, high-density polyiso cover board with Grade 1 compressive strength (min. 80 psi up to 110) and an R-value of 2.5.  ProtectoR HD offers excellent resistance to harsh rooftop conditions including hail, wind uplift, puncture and moisture in a competitive package.  ProtectoR HD provides reduced FM 1-90 fastening rates with as few as 8 fasteners per 4’x8’ board.

This is up to a 50% reduction in fasteners and plates required to achieve FM 1-90 over min. 22 ga steel or structural concrete decks as compared to other high-density polyiso cover boards.
