XPS Rigid Foam Board Insulation R-5, 1 in. x 2 ft. x 2 ft. (4 sq. ft.)

Extruded Polystyrene (XPS) Rigid Foam Insulation provides a diverse selection of insulation boards in various sizes, thicknesses, and edge styles, backed by a Lifetime Limited Warranty for the duration of the home or building's life. These foam insulation boards are simple to handle, score, cut, and install, requiring no special tools. Rigid foam insulation can be applied to wood, steel framing, or concrete walls. XPS is moisture-resistant and maintains its R-value even after exposure to standing water and wet soil. It is the only XPS foam to achieve GREENGUARD Gold Certification and the first to be certified by Scientific Certification Systems (SCS) for containing at least 20% recycled content.

• When using low-perm insulation, always verify the moisture vapor flow and dew point properties of the wall system, and consult local building codes for vapor retarder/barrier information
• For interior construction applications, painting is not recommended as it cannot be left exposed and must be covered by a 15-minute thermal barrier such as drywall
• For craft projects, acrylic or latex-based paints can be used with XPS products
