Rigid foam board insulation in gray, supplied as a flat panel for use as a continuous insulating layer on walls, ceilings and floors. Boards of this type are made from lightweight cellular plastic and are cut and fitted on site rather than being fitted into cavities like batt insulation.

At three-quarter inch thickness the panel is a thin-profile board, the kind used where a modest insulating layer or thermal break is wanted without giving up much room depth or pushing trim and siding details out of alignment. It handles like a sheet good, scores and snaps with a utility knife, and is light enough for one worker to place overhead.

Foam board is installed over framing or sheathing with cap-head fasteners, furring strips or a compatible construction adhesive, with joints butted tight and taped or sealed as the assembly requires.

Key Features

• Rigid cellular foam panel, gray
• Cuts cleanly by scoring with a utility knife and snapping, no power tools required
• Lightweight sheet that one person can carry and position
• Installed as a continuous layer over framing or sheathing rather than in cavities, reducing thermal bridging through studs
• Joints butt together and can be taped or sealed to limit air movement
• Fastened with cap-head nails or screws, furring strips, or foam-compatible adhesive
• Does not absorb or hold water the way fibrous insulation does

Applications

• Continuous insulation over exterior wall sheathing behind siding
