Rigid foam board insulation in a standard sheet format, used as continuous insulation over framing, under slabs, and against foundation walls. The gray color is typical of graphite-enhanced expanded polystyrene, where graphite particles are added to the foam cell structure to reduce radiant heat transfer.

Rigid foam is cut with a utility knife or fine-tooth saw and fastened with cap nails, plastic-cap screws, or construction adhesive rated for use with foam. Boards are typically installed with joints staggered and taped or sealed to limit air movement through the assembly.

Panels are lightweight and handled by one person, and unlike batt insulation they hold their shape and do not compress in the cavity or against masonry.

Key Features

• Gray graphite-type rigid foam board panel
• Closed-cell rigid foam construction holds its shape and resists compression
• Cuts cleanly with a utility knife or fine-tooth handsaw for field fitting
• Lightweight enough for single-person handling and installation
• Provides continuous insulation across framing members to reduce thermal bridging
• Joints can be taped or sealed to limit air movement through the assembly

Applications

• Continuous exterior insulation over wall sheathing or framing
• Foundation and basement wall insulation, interior or exterior side
• Under-slab and slab-edge insulation
• Crawl space wall and rim joist insulation
• Insulating furred-out masonry and concrete walls
• Roof deck and cathedral ceiling assemblies where rigid board is specified
