What Is Spray Foam Insulation?
Spray foam insulation is a modern alternative to traditional materials like fiberglass or cellulose. Applied as a liquid, it expands rapidly into a thick, durable foam that fills wall cavities, gaps, cracks, and hard‑to‑reach areas. Because of its expanding properties, spray foam creates an exceptional air seal—something traditional insulation materials cannot achieve on their own.
This makes spray foam a favorite among both residential and commercial builders. It’s ideal for improving energy efficiency, reducing air leakage, and providing long‑lasting thermal protection.
Open‑Cell vs. Closed‑Cell Spray Foam: What’s the Difference?
Spray foam insulation comes in two primary types: open‑cell and closed‑cell. Each offers unique benefits depending on your home’s structure, budget, and performance goals. Understanding the difference helps you choose the right material for your project.
Open‑Cell Spray Foam
Open‑cell spray foam is lighter, softer, and more flexible than closed‑cell foam. When applied, it expands significantly—often up to three inches—allowing it to fill irregular spaces with ease. This makes it ideal for:
- Attics
- Interior wall cavities
- Crawl spaces
- Basement walls
- Underside of roof decks
Because of its expansion and lower density, open‑cell foam typically requires only a single application to achieve effective air sealing.
Benefits of Open‑Cell Spray Foam
- Excellent soundproofing
- Mold‑resistant properties
- Lower cost compared to closed‑cell foam
- Allows bi‑directional drying (helps manage moisture)
- Ideal for hard‑to‑reach or irregular spaces
Open‑cell foam is a great choice when you want strong air sealing, noise reduction, and affordability.
Closed‑Cell Spray Foam
Closed‑cell spray foam is denser, more rigid, and offers a higher R‑value per inch than open‑cell foam. Because of its structure, it provides superior moisture resistance and adds structural strength to walls and framing.
Closed‑cell foam is commonly used in:
- Exterior walls
- Basements
- Crawl spaces
- Rim joists
- Areas prone to moisture
- Spaces requiring maximum insulation performance
Benefits of Closed‑Cell Spray Foam
- Higher R‑value per inch
- Exceptional air and moisture barrier
- Adds structural rigidity
- Ideal for flood‑prone or high‑moisture areas
- Provides long‑term durability
If you want maximum energy efficiency and moisture protection, closed‑cell foam is the premium choice.
