DuroFoam Plus 40 insulation is a Type 3, closed cell and moisture resistant insulation. With an R-value of 4.3 per inch for the life of the product, DuroFoam Plus 40 is a high compressive solution with a 40 psi compressive resistance. It is easy to install and can be used in many applications such as exterior sheathing, continuous insulation, basement floor, under slab insulation and cathedral ceilings. The addition of the laminated film to the top and bottom surfaces of DuroFoam Plus 40 insulation board provides a more durable product that is less susceptible to damage.

The higher compressive strength of DuroFoam Plus 40 makes it an excellent choice for under slab and below grade applications. Not only does it maintain its R-value for the life of the product, but provides the compressive resistance needed to meet strict building codes.

DuroFoam Plus insulation resists water absorption so it will retain its R-value even in applications where severe temperature differentials occur. Marking provided on the printed face of DuroFoam Plus insulation assist in cutting to required dimensions and spacing of fasteners into framing.
