Spray Foam Insulation on the day: sealing, depth and cleanup
Spray foam is powerful and frequently oversold. It air seals and insulates in one operation, which is genuinely valuable, but it costs several times what blown insulation does and there are houses where it is simply the wrong answer.
Closed cell is denser, adds structural rigidity and resists moisture. Open cell is cheaper, more permeable and better at sound. Using one where the other belongs is the most common specification error in the trade.
Foam over damp or unsound framing seals the moisture in permanently. If there is a crawl space or roof leak problem, that gets solved first — not covered up.
Sealing a house tightly changes how combustion appliances behave. A gas water heater that vented happily in a leaky house can backdraft in a tight one, so that gets checked before rather than discovered after.

FAQ
Spray Foam Insulation: what homeowners want to know
Open-cell or closed-cell spray foam?
Open-cell for walls and roof decks where a vapor-permeable, sound-absorbing foam at a lower cost is the aim; closed-cell where a vapor barrier, structural stiffening or a thinner application is needed — rim joists, crawl space walls, under a floor. Both are applied at a specified thickness by a trained crew; foam that was applied too thick or over damp framing is a problem, and it is why the preparation matters.
Is spray foam worth the extra cost over blown insulation?
Where it does what blown insulation cannot — sealing and insulating in one, in a roof deck to bring the attic inside the envelope, in a crawl space, in a rim joist — yes. For topping up a flat attic floor, blown insulation over proper air sealing does the job for far less. The right answer is usually a combination, and it depends on the house.
