Open Cell, Closed Cell and What They Cost

Spray Foam Insulation in East Gull Lake raises the same question in almost every home: open cell or closed cell? East Gull Lake is a Cass County city of 986 residents where Gull Lake is the largest lake within the city limits and resorts such as Cragun's, Madden's and Kavanaugh's line the shore. Homes range from older cottages to large newer lake houses, and the right foam often varies from room to room.

Closed-cell foam

Dense and rigid, closed-cell foam rates about R-5 to R-7 per inch in HomeGuide's figures, and it slows vapor and resists water. That suits rim joists, crawl space and basement walls, floors that sit over open air, and shallow roof framing where every inch counts. HomeGuide lists closed-cell at $3.00 to $5.00 per square foot installed.

Open-cell foam

Softer and more expansive, open-cell foam gets about R-3.5 to R-3.7 per inch. It seals air well and dampens sound, but it lets vapor through, so it needs a vapor control layer in Minnesota's cold climate. It fits deep roof framing, interior walls for sound and large cavities where depth is not a constraint. HomeGuide lists it at $1.50 to $3.50 per square foot.

Those ranges are national survey figures from HomeGuide. Your price depends on access, thickness and how many areas are involved, so the written estimate we give after the visit is the number that counts.

Local conditions

Minnesota's energy code map places Cass County in Climate Zone 7, where the Department of Energy's goal for an attic with no insulation is R-60. East Gull Lake had 792 housing units in 2010, many of them near the water, where damp summer air makes vapor control especially important.

East Gull Lake Questions

Which foam is better for an East Gull Lake basement?

Closed-cell is usually the choice for basement walls and rim joists because it slows vapor and does not absorb water. Open-cell is rarely used below grade.

Why does open-cell foam need a vapor barrier in Minnesota?

Open-cell lets water vapor pass through. In a cold climate, warm indoor moisture can move through it and condense on cold surfaces. A vapor control layer on the warm side prevents that.

How much does spray foam cost per square foot?

HomeGuide lists open-cell at $1.50 to $3.50 and closed-cell at $3.00 to $5.00 per square foot. Your written estimate after the visit is your actual price.

Can a single house use both types of foam?

Yes, and many do. Closed-cell might go on the rim joists and floors, with open-cell in a roof or interior walls. We explain the reason for each choice.
