Closed-Cell Spray Foam
A higher-density spray polyurethane foam that delivers a dense, rigid insulation layer for interior spaces and demanding exterior wall and roof assemblies.
What it is
Understanding Closed-Cell Spray Foam
Closed-cell spray foam is a higher-density spray polyurethane foam with cells that cure into a dense, rigid structure. It provides thermal resistance, can help reduce air movement through an assembly, and adds durable coverage where space is limited. Its rigid finish makes it especially useful in metal buildings, garages, and other demanding spaces.
How It Works
The material is spray-applied in layers and cures in place, adhering to many prepared surfaces. Its density allows it to deliver substantial thermal resistance in limited thickness, while its moisture-related characteristics depend on the installed thickness and assembly. A professional evaluation helps determine the right approach for interior cavities, exterior walls, roof decks, and retrofits.
Common applications
- Interior walls and ceilings
- Exterior wall assemblies
- Exterior roof decks
- Metal building assemblies
- Garages and workshops
- New construction
- Targeted retrofit areas
- Areas with limited cavity depth

Energy-efficiency considerations
Closed-cell foam can support an efficient building envelope when it is selected for the correct location and installed as part of a complete strategy. It is not universally better than every other insulation type.
Installation considerations
The application surface, layer thickness, curing conditions, and intended assembly all need professional evaluation. Building-code and moisture-control requirements should be considered before installation.
Important considerations
Plan Around the Full Building Assembly
Closed-cell foam has moisture-related characteristics that must be considered with the complete wall or roof assembly.
The right material depends on the application, budget, existing conditions, and project goals.
Professional installation is important for correct coverage, thickness, and adhesion.
