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.
