Foam Sheathing Board Insulation
Foam sheathing board is the latest continuous insulation solution from Johns Manville, made from a uniform closed-cell polyisocyanurate foam core. We offer three foam board products that are lightweight, non-corrosive and easy to handle and cut.
With R-values up to R-25 and a thinner profile, foam board offers an efficient way to dramatically increase the overall thermal efficiency of walls and roofs. Manufactured to meet the latest environmental regulations, it works well with all other types of JM high-performance commercial and residential products.
Foam board can be used in both new and retrofit construction, including interior and exterior insulation, and roof decks. Its range of uses in walls includes masonry cavity walls, below-grade basement walls, crawlspaces, framed walls (wood and metal), pre-engineered metal buildings, cathedral and flat ceilings.
CI MAX™ foam sheathing board is designed for exposed interior wall use, made from a uniform closed-cell polyisocyanurate foam core bonded on each side to a printed foil and glass mat facer for lightweight, noncorrosive thermal efficiency.
AP™ Foil-Faced foam sheathing board is lightweight, uniform closed-cell polyisocyanurate foam core bonded on each side to a foil facer for superior wall thermal efficiency, moisture resistance and fire safety.
R-Panel™ Roof Insulation is a rigid roof insulation board composed of closed cell polyisocyanurate foam core with high thermal efficiency that is compatible with BUR, modified bitumen and single-ply membrane roofing systems.
