Spray Foam vs. Cellulose vs. Fiberglass: Which Is Right?

Each material has its place. Here is an honest look at cost, R-value, and best use to help you decide.

Spray foam

Seals and insulates in one step with the highest R-value per inch and excellent moisture resistance, making it ideal for crawl spaces and rim joists. It is the premium option.

Cellulose

Eco-friendly blown-in fiber that fills gaps and dampens sound, perfect for bringing older attics up to modern R-values at a moderate cost.

Fiberglass & batt

The budget-friendly, proven choice for walls, attics, and floors when installed without gaps or compression. We help you choose the right material for each space and budget.
