Attics in Indianapolis.
Open or closed cell spray foam for attics across central Indiana, applied where your attic actually needs the seal.
How we do it.
- If your ductwork is in the attic, we seal the roof deck.Foam goes on the underside of the roof, so the attic and your HVAC lines sit inside the seal.
- If it isn't, the attic floor can be sealed instead.Foam goes down onto the top of the ceiling below. Special situations get a look in person.
- Old insulation comes out first.Spray foam can't be installed correctly over it.
- Exposed foam is fine up there.In an attic, the foam can be left exposed.
What Indianapolis buildings are like.
Indianapolis is the largest town we cover in Marion County, and half of its 401,428 homes were standing before 1973. That is the era we do most of our retrofit work in, and it is why we usually start with the attic and the crawlspace.

Foam and thickness.
| Foam | Where it goes | Typical thickness | R-value per inch |
|---|---|---|---|
| Open cell | Roof deck or attic floor | 6 in + | R-3.8 to 4.2 |
| Closed cell | Roof deck or attic floor | 3 in + | R-7.6 to 8.1 |
R-value measures how well insulation holds back heat. Higher is better. Closed cell is rigid and also blocks moisture; open cell is softer and dampens sound. Ranges are from Universal Polymers (UPC) data sheets, tested at 1 inch. We choose the foam for each job. See the data sheets
Questions.
Do you do attics in Indianapolis?
Yes. Indianapolis is 32.4 miles from our base in Anderson, and attics is one of the twenty things we spray. That is a routine trip for us, on jobs of any size. Tell us about the building and we'll quote it.
Which foam goes in a Indianapolis attic?
Marion County is in climate zone 5, the colder of the two zones Indiana spans. We spray both open cell (R-3.8 to 4.2 per inch) and closed cell (R-7.6 to 8.1 per inch), and which one a attic needs depends on moisture and what the foam is going on. We tell you when we quote.
