Spray Foam Insulation
Highest R-value per inch — one option among several, matched to the right application
Overview
How Spray Foam Works
Spray foam offers the highest R-value per inch of any common insulation material and creates its own air seal as it's applied, which makes it a strong option for crawl spaces, rim joists, and tight or irregular cavities. It isn't the right fit for every part of every home — we'll tell you honestly where it earns its cost and where blown-in or batt makes more sense.

Spray Foam — Frequently Asked Questions
It depends on the application — spray foam's air-sealing properties make it worth the premium in crawl spaces, rim joists, and irregular cavities, but for a straightforward open attic, blown-in or batt often delivers comparable winter performance at a lower cost. We'll give you an honest comparison for your specific project.
