Closed-cell spray foam is the dense, rigid type of spray foam. It cures into a hard layer that bonds to wood, metal and concrete and provides about R-6 to R-7 per inch, the highest R-value of any common insulation. It also resists water and adds strength to the surfaces it covers.
In Bixby, that combination is useful in several places: vaulted ceilings in custom homes where rafters are too shallow for other insulation, damp areas near the Arkansas River, garages and bonus rooms, and the metal shops and barns on acreage south of town.
It costs more than open-cell foam, so we use it where it earns its price. Every free estimate shows where closed-cell goes, how thick, and the R-value you will get.
Bixby tip
Closed-cell foam cures best in passes of roughly 1.5 to 2 inches. Ask how many passes your project needs if the plan calls for 3 inches or more.
Where Closed-Cell Foam Makes the Most Sense
- ✓Vaulted and cathedral ceilings
- ✓Garages and walls next to living space
- ✓Damp areas near the river
- ✓Metal shops and pole barns
- ✓Rim joists and band boards
- ✓New construction walls that need maximum R-value
Vapor Barriers, Air Gaps and Thickness
At about 1.5 inches, closed-cell foam becomes a vapor retarder, so a separate plastic vapor barrier is generally not needed and can even trap moisture. It also needs no air gap; it bonds directly to the surface.
Typical thicknesses are about 1 inch for condensation control on metal, 2 to 3 inches in walls, and 3 to 5 inches in vaulted ceilings. It runs about $1.00 to $2.00 per board foot installed.
