How much does spray foam insulation cost in Carson City?
Spray foam insulation in Carson City usually costs about $2 to $5 per square foot of area sprayed, and that's the going rate around here, not a quote from us. Your own number comes from the on-site estimate, once I've seen how much space there is and what's already in it.
How long do we have to stay out of the house after spray foam?
Plan on at least 24 hours away, which is the minimum consumer safety guidance gives for spray foam. The safe time to come back varies with the product, the kind of house and whether children or older relatives live there, and EPA guidance says to wait until the foam has cured and the house has been aired out and cleaned, so line up a place to stay before we set the day. If anyone at home has asthma, respiratory allergies, a skin condition or a past reaction to isocyanates, the chemicals in spray foam, the guidance says to look over the product information carefully, and a different insulation may suit your house better.
Should I choose open-cell or closed-cell spray foam?
Pick the foam that suits how moisture moves in that space, because open-cell is excellent at stopping air but lets vapor through, while closed-cell foam, the dense kind, blocks moisture too. In a vented attic, federal energy guidance has open-cell working as the air barrier at 5.5 inches or more and closed-cell at 1.5 inches or more, so ask any contractor which thickness their quote assumes. On a worn roof, closed-cell sprayed at the roof can hide a leak because water won't pass through it, which is why I look at the roof before suggesting it.
Does spray foam in the attic need a fire barrier?
It can, because some foam makers require a thermal or ignition barrier, a protective layer over the foam, when it's sprayed at the roof. Ask whether a quote includes that covering when the product calls for one, since two quotes only compare fairly when they cover the same job. When the foam maker requires it, we include it in ours.
