DuroFoam® Insulation
Durable, rigid insulation

DuroFoam® Insulation is used in Cathedral Ceiling, Continuous Insulation, Exterior Foundation, Interior Basement Walls, Basement Floor and Under Slab.


DuroFoam insulation is a closed cell and moisture resistant insulation with a
green film laminated to one side, and a silver film on the other side. It is
easy to install and can be used in many applications; exterior sheathing,
continuous insulation, basement floor, under slab insulation and cathedral
ceilings. It has an R-value of 3.75/inch for the life of the product. The
addition of the laminated film to the top and bottom surfaces of DuroFoam
insulation board provides a more durable product that is less susceptible
to damage.

The reflective facer on DuroFoam insulation contains a thin layer of foil
embedded within the film. The reflective facer does not increase nominal
R-value of DuroFoam insulation (for additional information see Plasti-Fab
PIB 253 - Facts About Thermal Resistance of Reflective Insulation).
