What is spray foam insulation?
Spray foam is a liquid that expands into a solid foam. It fills cracks, seams, and gaps that other insulation types often miss.
That matters because air leaks are a big reason homes feel drafty and uneven. Spray foam helps block that uncontrolled airflow, so your house holds temperature better.
There are two main types: open-cell and closed-cell. The right choice depends on the area, moisture risk, and what you are trying to fix.
Open-cell
Lighter foam. Often used where you want air sealing without maximum density.
Closed-cell
Denser foam with higher R-value per inch. Often used where strength and moisture resistance matters.
When do you need spray foam?
If your main issue is air leakage, spray foam is usually the strongest fix.
- You feel drafts even when the heat is running
- Some rooms stay colder or hotter than the rest of the house
- Your home is older and has lots of small air leaks
- Rim joists, crawl spaces, or basements feel damp or chilly
- You want the best performance in tight or irregular cavities
- You are upgrading an attic and want real air sealing, not just more insulation
How does spray foam work?
Spray foam is applied as a liquid and expands within seconds. That expansion is what makes it different. It fills the small cracks and seams where air sneaks through.
Once those leaks are sealed, your home holds temperature better. That usually means fewer drafts, fewer hot or cold spots, and less work for your HVAC.
The key is applying the right foam, in the right thickness, in the right location. We focus on prep, ventilation, and clean coverage so the result performs like it should.
