Open-cell foam insulation in Memphis TN - a sealed attic that stops leaking air
Hot upstairs rooms and ducts baking in the attic? We spray foam under the roof deck so the attic sits inside the house you cool.
Is open-cell spray foam right for my attic?
Open-cell foam insulation is a soft spray foam we apply to the underside of the roof deck in Memphis, TN homes. It insulates and blocks air leaks in one pass, so the attic becomes a sealed space your system heats and cools along with the rest of the house.
It's worth weighing when your ducts or heating and cooling equipment sit in the attic, when you plan to finish the attic into living space, or when the roof is hard to vent, because in those houses the ducts are sitting in the hottest part of the house. If none of that fits, attic air sealing usually does more for the money, and I'll say so. The price moves with the size of the roof, how deep we spray, any roof repair and whether the foam needs a protective coating. The schedule turns on that roof work and the time you're out of the house while the foam cures. Your own figure comes from the estimate, once we've seen the attic and the roof.
How we install open-cell foam insulation
I start with the roof, because foam sprayed under a deck that leaks hides the leak instead of stopping it. We look the roof over first. If it needs repair, I tell you before we spray, and if it's close to the end of its life, replacing it first belongs in your budget. Then our installers cover floors and stored items, close off the old roof vents the sealed attic no longer needs, and spray the underside of the deck and the gable walls. We keep the depth even out to the edges where the roof meets the walls, because thin edges are where foam jobs usually fall short, and we clean up before you come back in.
We also take on commercial insulation for property managers and building owners, with the same care about doing things in order. If you'd like the space under the house looked at too, ask about our crawl space vapor barrier work when I'm out.
Whole roof deck with ducts above
This suits a house with the air handler and duct runs in the attic, because sealing the roofline brings that equipment inside the space you cool. It's the job most people mean when they ask about spray foam.
The room over the garage
Foam on the sloped ceiling and short walls fits a bonus room that runs hot, because it fills the odd angles and gaps that batts leave open. We usually price it as its own area at the estimate.
Air sealing and loose fill instead
If your ducts aren't in the attic, I usually point you to sealing the gaps and a top-up of blown-in insulation, which is loose fill blown through a hose. Foam costs more, and without ducts up there it rarely pays its way.
Permits and attics for open-cell foam insulation in Memphis
Construction Enforcement issues construction permits and inspects building work in Memphis, Germantown, Lakeland, Millington and the unincorporated parts of the county, and it holds that work to the state's building code. Whether your foam job needs a permit is their call, so we check rather than guess. When a job calls for one, we handle the application and set up the inspections with the city or county office that covers your address.
We're based in Memphis and work across the cities around it in Tennessee, Mississippi and Arkansas. A lot of the houses we see have the air handler and duct runs in the attic, plus hip roofs and add-on sections that are hard to vent, and we find the same setup on jobs in Southaven.

Why call us for open-cell foam
I do the estimate myself
I come out to look at your attic and roof and give the estimate myself, and our installers do the spraying. You hear the plan from the person who decides how the job is done.
A heating and cooling background
I spent years in heating and cooling before starting this business in 2021, so I treat your ducts and equipment as part of the attic plan. On a foam job that matters, because the ductwork is usually the reason to seal the attic at all.
Licensed and insured on foam jobs
We're licensed and insured. In Tennessee, the Department of Commerce and Insurance requires contractors bidding directly to you to hold a license on projects of $25,000 and more, so it's fair to ask any bidder about theirs.

Spray foam questions from Memphis homeowners
Is open-cell or closed-cell spray foam better for a Memphis attic?
For most attics with ducts up there, open-cell under the roof deck is our usual pick. Open-cell foam has an R-value, its resistance to heat, of about 3.6 per inch and lets moisture vapor pass, while typical closed-cell foam runs about R-6 per inch and slows moisture. Closed-cell earns its higher price where space is tight or moisture has to be stopped, and a roof deck with room between the rafters usually doesn't need that.
How much does spray foam insulation cost in Memphis, TN?
Spray foam insulation in Memphis usually costs about $1 to $5 per square foot, and that range covers spray foam in general, not open-cell alone. Roof area, foam depth, a protective coating and any roof repair decide where your job lands, and the estimate gives you your figure. Low-income homeowners who live in their Shelby County home can apply to MLGW's Share the Pennies program, whose grants list attic insulation among eligible repairs.
How long do we have to stay out of the house after spray foam?
Plan on being out from the start of spraying until the foam has cured and the house has been aired out and cleaned, which is what EPA guidance says. Some foam makers recommend 24 hours for professional high-pressure foam, but it varies, so book a night away for the family and the pets. We give you the re-entry time, when it's safe to come back, for the foam we're using.
Does open-cell spray foam have to be covered with drywall or a coating?
Sometimes. A thermal or ignition barrier, a coating or drywall that shields the foam from flame, goes over it where the product or the code requires one, and not every spray foam needs it. We sort out which applies at the estimate, because it changes the work and the price.
How do I keep moisture from building up in an attic sealed with foam?
Plan a way to remove it before the attic is sealed, because closing the vents takes away the path moisture used to leave by. Usually that means tying the attic into the heating and cooling system or adding a dehumidifier, and we build that into the plan instead of leaving it for later.
Is it safe to spray foam an attic with a gas furnace or water heater up there?
It is when those appliances are direct-vent, sealed-combustion units, the kind that pull air from outside and vent back outdoors. A sealed attic shouldn't be feeding an open burner, so I check what's up there at the estimate and tell you plainly if a unit has to change before we spray.
