Is open-cell spray foam the right insulation for my house?

Open-cell foam insulation is a soft spray foam that we put into attics and walls in San Angelo, TX, where it expands to fill the gaps, stops drafts and quiets the rooms around it.

Most calls start with a hot upstairs, a room over the garage that never feels right or a power bill that keeps climbing, and the first thing I figure out is whether foam is even the answer, because sometimes sealing the gaps and adding loose fill does the job for less. The price turns on how many square feet we're covering, how deep the foam goes, whether old insulation has to come out first and how hard the space is to get into. The schedule turns mostly on that removal and prep, plus the time your family spends out of the house while the foam goes in. If you're weighing it against closed-cell foam, the questions below lay out the trade, and your estimate gives you the figure for your own house.

How we put in open-cell foam insulation

Open-cell is the easier foam on the budget and it quiets a room nicely, so I point people to it when price and noise matter more than getting the most out of every inch. We start with what's already in the attic or wall, pulling out anything soaked or full of droppings through our insulation removal work, because new foam laid over a problem just hides it. Then we close the gaps the foam won't reach on its own, mask off what needs protecting, spray an even coat from edge to edge instead of piling it up in the middle, and clean up before we leave. When the foam goes under the roof deck, I want that attic sealed tight first so moisture doesn't turn into trouble.

Business owners call us about shops and metal buildings too, and that falls under our commercial insulation work. If the cold is coming up through the floors, the fix may be under the house, and a crawl space vapor barrier keeps ground moisture down before any insulation goes in.

  • Under the attic roof deck

    This suits a house where the ductwork or the air handler lives in the attic, because spraying the underside of the roof brings that space inside the part of the house you heat and cool. It's also the job where I'm strictest about checking the roof and sealing the attic before we spray.

  • Inside open walls

    Walls make sense when they're already open for a remodel or an addition, or when you want a quieter bedroom, office or room next to the garage. The foam fills the whole cavity around wires and boxes, so there's no gap left for a draft to slip through.

Open-cell foam insulation in San Angelo: permits and what we find

Permits here come from the city's Building Permits & Inspections office, and its handouts list new construction, additions and renovations without naming insulation, so that list doesn't settle whether your foam job needs one. We check with that office on every job and take care of any permit it calls for, so you don't have to chase it.

The houses we work in tend to show the same things. Older homes have tired attics with a thin layer that's been walked flat or soaked by an old roof leak, rooms over garages run hotter than the rest of the house, and shops and metal buildings often have next to nothing in them. We see those patterns on jobs all over San Angelo, and it's why I look at what's already up there before I say a word about foam.

Frequently asked questions

Should I get open-cell or closed-cell spray foam for my house?

Open-cell is usually the better pick when a lower price and quieter rooms matter more to you than getting the most insulation out of every inch. Closed-cell is about twice as efficient per inch and costs more, while open-cell is a much better sound barrier. Open-cell expands to about 3 inches per layer, so walls only fit one layer but attics often have room for two, which is why it gives you more in an attic with space to spare.

How much does open-cell spray foam insulation cost in San Angelo?

Open-cell spray foam in San Angelo usually costs about $0.60 to $0.90 per board foot, which is one square foot of foam an inch thick. That's what the work typically runs around here, not our quote, and your own figure depends on the square footage, how many layers go in and the prep the space needs. I'll give you that number at the estimate.

Do we have to leave the house when spray foam insulation goes in?

Yes, plan to be out while we spray and for at least 24 hours after, which is what federal consumer safety staff advise. Line up a place for the family and pets before the crew arrives, and ask us which foam we're using and what safety steps we'll take. If anyone at home has asthma, respiratory allergies or a skin condition, go over the product information with us first, and if it's a concern we'll talk about a different insulation.

What causes moisture problems with spray foam under a roof deck?

Roof leaks and condensation cause most of them, and foam under the roof deck has had only isolated failures, such as rotted sheathing, the wood layer under your shingles. These roofs can work well as long as the attic is airtight and winter humidity in the house stays under control. So I want any roof leak fixed before we spray, and I want that attic sealed tight.

Does open-cell spray foam block moisture?

No, open-cell foam stops air, but water vapor can still pass through it. In a damp spot like a crawl space it isn't the foam I'd reach for, and a crawl space vapor barrier or closed-cell foam usually makes more sense.

How do I know if spray foam needs to be covered with drywall?

Foam facing the inside of your living space should be covered with a fire-rated material such as drywall, according to federal building guidance. Foam sprayed into a wall that gets closed up with drywall is covered that way, and at the estimate I'll point out any spot, like a bonus room or a garage wall, where the foam would otherwise be left showing.

  • Commercial insulation

    When the building is a shop, warehouse or metal building rather than a house, this is how we insulate it.

  • Crawl space vapor barrier

    If the floors feel cold or the crawl space smells damp, a barrier on the ground is often the first fix to make.
