Is closed-cell foam worth it for your house?
Closed-cell foam insulation is a dense spray foam that hardens into a rigid layer, and in San Angelo homes and shops we use it where you need the air sealed and moisture held back along with the heat. Its R-value, the number for how well insulation slows heat, runs about R-6 per inch, and at its usual thickness it also stops moisture vapor from passing through.
Most people who call about it have a room over the garage that never feels right, cold floors over a crawl space or a metal shop, and they've heard foam is the fix. The price mostly turns on how much area gets foam and how thick it goes, since closed-cell expands less than open-cell and uses more material to fill the same space. It also depends on whether old insulation has to come out first through insulation removal. That same prep sets the schedule, along with lining up a place for your family to stay while the foam goes in, and the estimate gives you the figure for your house.
How we install closed-cell foam insulation
I start by looking at what's already there and how many inches you have, because foam sprayed over insulation that got soaked or full of droppings just seals the problem in, so that comes out first. Closed-cell costs more, so I only point you to it when you need the rigid layer and the moisture blocking it brings, and if anyone at home has asthma or a chemical sensitivity, we talk that through before we pick any foam at all. On install day our crew covers anything that shouldn't get foam, makes sure the gaps around can lights, pipes and the hatch get closed, and sprays an even layer that's as full at the edges as it is in the middle, then trims it back and cleans up.
If a space only needs the air sealed and the heat slowed, open-cell foam insulation does that for less money. Shops, metal buildings and offices get the same care under our commercial insulation work.
Rim joists and tight framing
This suits the board that runs along the top of your foundation wall, where outside air sneaks in under the floor. A thin layer of closed-cell seals that gap where open-cell would need a lot more depth.
Metal buildings and shops
This suits steel walls and roof panels, because the foam bonds right to the metal and keeps moisture vapor from reaching it. You end up with one rigid layer instead of batts sagging off the purlins.
Closed-cell foam insulation in San Angelo and what the city decides
Whether a foam job needs a permit is up to the city's Building Permits & Inspections office, so I check with them on every job and we take care of any permit they call for, and you don't have to chase it. The city works from the international energy and home building codes, and when a permit is needed, residential applications go to the city by email, which is our part of the job.
Around San Angelo and the cities around it, we find a lot of rooms over garages, cold floors over crawl spaces and metal shop buildings. Those are the spots where I'll usually point you to closed-cell, because that's where a rigid, sealed layer earns its price.

Frequently asked questions
What's the difference between closed-cell and open-cell spray foam?
Closed-cell foam dries hard and rigid and, at its usual thickness, stops moisture vapor, while open-cell stays soft and doesn't give you that moisture block. Open-cell costs less, so it's usually the better pick when you only need the air seal and the insulation.
How much does closed-cell spray foam insulation cost in San Angelo?
Closed-cell spray foam in San Angelo usually runs about $1 to $1.40 per board foot, which is one square foot of foam one inch thick. That's the going rate in the area, not our quote, and your total depends on how much area gets foam and how thick it goes. I'll give you your number when I come out.
How long does it take before we can go back in the house after spray foam?
Plan on being out during the install and for at least 24 hours after, which is what federal product safety staff advise. EPA guidance adds that you shouldn't come back until the foam has finished curing and the house has been aired out and cleaned. We agree on your return time before the crew starts, so you can line up a place for the kids and pets.
Is spray foam insulation safe if someone in my house has asthma?
It can be, but federal product safety staff say people with asthma, respiratory allergies, skin conditions or a past isocyanate sensitization should read the product information closely first. Isocyanate is a chemical used to make the foam. If the product isn't a fit, those households can look at another type of insulation instead, and we'll go over the options with you.
How thick does closed-cell foam need to be on rim joists?
To seal the air at a rim joist, closed-cell foam needs a finished layer at least 1.5 inches thick. Open-cell needs at least 5.5 inches to do the same job, which is why closed-cell is usually the pick for that tight spot.
What is the best way to insulate an attic, spray foam or blown-in?
For most attics, sealing the gaps and topping up the loose fill does the job for less than foam. Foam costs more because it seals air while it insulates, and it usually earns that when your ductwork runs through the attic. I'll tell you which one yours needs once I'm up there.
