Spray foam insulation FAQ
How much does spray foam insulation cost in Metairie?
Open-cell foam typically runs about $0.45 to $0.90 per board foot and closed-cell about $1.00 to $2.20, so many attic jobs land between $5,000 and $15,000. See our spray foam cost guide.
Is open-cell or closed-cell foam better for Metairie homes?
Open-cell is common on attic roof decks. Closed-cell is the usual choice under raised floors, in crawl spaces and on metal buildings because it resists moisture. See open-cell vs. closed-cell.
Will spray foam cause termite problems?
Foam doesn't feed termites, but it can hide them. In heavy-termite areas like ours, foam should stay clear of the ground so inspectors can see the foundation. Read spray foam and Formosan termites.
How long until I can go back in the house?
Most manufacturers recommend staying out of the work area for at least 24 hours while the foam cures and the space ventilates. Follow your installer's instructions.
Are there rebates for spray foam in Louisiana?
Entergy's efficiency programs offer incentives through participating contractors, and amounts change each year. The federal insulation tax credit ended for work completed after December 31, 2025. See rebates and tax credits.
Do you install the foam yourselves?
No. Metairie Spray Foam Insulation is a free referral service. We connect you with an independent local installer, who gives you a written estimate and does the work.
What is spray foam insulation?
A two-part foam sprayed as a liquid that expands, sticks to surfaces and hardens. It insulates and air-seals in one step.
How much R-value does spray foam give?
Open-cell foam gives about R-3.5 to R-4 per inch, and closed-cell about R-6 to R-7 per inch.
Can spray foam be removed later?
It can be cut and scraped off, but it's labor-intensive. Plan carefully before installation.
Does spray foam stop noise?
Open-cell foam dampens airborne sound well, which helps near busy roads and the airport.
Is spray foam safe once cured?
Cured foam is considered inert. Follow the manufacturer's re-entry time during installation.
Will spray foam help with humidity in my house?
It keeps humid outdoor air out of attics, crawl spaces and floors. A sealed attic may still need dehumidification.
Does spray foam affect home insurance?
Some insurers and inspectors ask about foam on the roof deck. Keep your installer's records and ask your agent if you have concerns.
