White rigid foam board of the type used for continuous insulation and general sheathing work. Expanded polystyrene boards like this one are lightweight, dimensionally stable and easy to handle on a ladder or scaffold by a single worker.

The thin profile suits jobs where a modest thermal break is wanted without building out wall or ceiling depth much: behind siding, over masonry before furring, or as a backer layer under finish materials. Boards score and snap cleanly with a utility knife and straightedge, and can be trimmed around outlets, pipe penetrations and framing irregularities without special tools.

Foam board is combustible and, in habitable spaces, is normally covered by an approved finish material such as gypsum board. Fasten with wide-head nails, plastic-cap fasteners or foam-compatible adhesive, and tape or seal board joints where a continuous layer is intended.

Key Features

• White rigid foam insulation board
• Lightweight panel that one worker can carry and place
• Scores and snaps with a utility knife; trims easily around penetrations
• Thin profile adds insulation value without significantly increasing assembly depth
• Non-structural; used as an insulating layer rather than a bracing sheathing
• Accepts foam-compatible construction adhesive and wide-head or cap fasteners
• Requires a code-approved covering in occupied spaces

Applications

• Continuous insulation layer behind siding or over masonry walls

• Insulating foundation, crawl space and rim joist areas
• Garage and accessory building wall and ceiling insulation
• Insulating board for cold-room, duct chase and utility enclosures
• Cut-to-fit filler pieces between framing members
