## Spray foam insulation Spray foam insulates and air seals in one step. That makes it the right material in specific places — and an expensive overkill in others. Here is where it actually earns its cost. ### Closed-cell vs open-cell | | Closed-cell | Open-cell | |---|---|---| | R per inch | ~R-6.5 to R-7 | ~R-3.6 to R-3.8 | | Vapor barrier | Yes at 2"+ | No | | Water resistant | Yes | No | | Adds structural rigidity | Yes | No | | Cost per board foot | $1.25 – $2.00 | $0.45 – $0.90 | For most Minnesota applications — rim joists, crawlspaces, below-grade, cathedral ceilings — **closed-cell** is the correct product because it handles moisture and hits high R in a thin cavity. Open-cell makes sense in interior sound-deadening walls and in deep attic applications where cost matters more than moisture control. ### Where foam is worth the money - **Rim joists** — the single best foam application in any Minnesota house - **Cathedral and vaulted ceilings** — no room for R-49 of blown material, and no vent channel - **Crawlspaces** — walls and rim, as part of encapsulation - **Bonus rooms over garages** — the classic freezing-floor room - **Cantilevers and overhangs** - **Additions and new framing** where the wall is open anyway - **Odd geometry** — trusses, chases, and framing that batts cannot fill cleanly ### Where it usually is not An open attic floor. You can hit R-60 with blown cellulose for a third of the cost of foam, and the attic floor is easy to air seal separately. Foam belongs where you cannot get depth or where you need moisture control. ### Planning ranges (Twin Cities, estimates) | Work | Typical range | |---|---| | Closed-cell, per board foot | $1.25 – $2.00 | | Open-cell, per board foot | $0.45 – $0.90 | | Rim joist, average home | $1,200 – $2,800 | | Cathedral ceiling, 600 sq ft | $4,000 – $8,000 | | Crawlspace walls and rim | $3,000 – $7,500 | | Bonus room over garage | $2,500 – $6,000 | Estimates for planning. ### Practical notes Foam is installed to a temperature range and needs the space vacated during application and curing — typically 24 hours. It expands hard enough to bow framing if over-applied, so lift thickness matters. And once it is in, it is in; plan wiring and plumbing runs before the foam, not after.
