When selecting insulation for your property, it's essential to understand the difference between open cell and closed cell spray foam. Each type offers distinct advantages depending on your building’s structure, the local climate, and your budget. Let’s dive into the details to help you make an informed decision for your next project.
What Is Open-Cell Spray Foam?
Open cell spray foam is a lightweight, flexible insulation option. It expands to fill even the smallest cracks and gaps, making it ideal for:
Crawl spaces, basements, and attics
Metal buildings and barndominiums
Applications needing moisture protection
Key Features:
R-Value: ~R-3.8 per inch
Density: ~0.5 lb/ft³
Air Barrier: Effective at 3.75” thickness
Vapor Barrier: ❌ Not a vapor barrier
Open cell foam offers excellent sound dampening and is often more cost effective for large areas. However, it doesn't resist moisture like closed cell foam does, making it better suited for interior spaces.
Cost Differences: Open-Cell vs. Closed-Cell
While open cell spray foam may have a lower upfront cost, it requires more thickness to achieve the same R-value as closed-cell foam. So depending on your goals whether it's budget savings or long-term performance one may suit your needs better.
Which Type Is Best for Homes in Sumner & Northeast Texas?
In Northeast Texas, we experience wide temperature swings, from cold winters to hot, humid summers. That’s why closed cell spray foam is often the better long-term investment especially in:
Attics or roofs
Crawl spaces prone to condensation
Metal structures
However, open cell foam can still be a great choice for interior walls or homes with smaller insulation needs where sound control is a priority.

Frequently Asked Questions
What’s the difference in R-value between open and closed cell foam?
Closed cell foam offers an R-value of about R7 per inch, while open cell foam provides around R 3.8 per inch. That means a closed cell performs better with less thickness.
Can I use open-cell foam in my attic?
Yes but in Texas climates, closed cell is often preferred in attics because it provides a vapor barrier and holds up better against humidity.
Is spray foam better than fiberglass or cellulose?
Yes. Spray foam expands to seal air leaks better than traditional insulation, improving both energy efficiency and indoor air quality.
Does closed-cell spray foam add strength to a structure?
Yes! It adds rigidity to walls and roofs, making it ideal for metal buildings or structures in high wind areas.
