Crawlspaces in Lawrence.
Closed cell spray foam for crawlspaces: insulation, a moisture barrier and a vapor barrier in one layer.
How we do it.
- Closed cell, 2 inches or more.It's a moisture barrier, a vapor barrier and an air barrier.
- Surfaces have to be dry.Moisture has to be below 8% before we spray.
- We need room to work.Foam is sprayed from 18 to 24 inches away, so the crawlspace needs clear access.
- Want it fully encapsulated?Encapsulation adds a vapor barrier with its own 10-year warranty.

Foam and thickness.
| Foam | Where it goes | Typical thickness | R-value per inch |
|---|---|---|---|
| Closed cell | Crawlspace | 2 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 crawlspaces in Lawrence?
Yes. Lawrence is 22.2 miles from our base in Anderson, and crawlspaces 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 Lawrence crawlspace?
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 crawlspace needs depends on moisture and what the foam is going on. We tell you when we quote.
