If you’ve been researching home insulation, you’ve probably come across spray foam, fiberglass, and cellulose. Each has its place—but spray foam stands out for its energy performance, air sealing, and long-term durability.
Of course, it also comes with a higher price tag. So… is spray foam insulation really worth it?
Let’s break it down.
What Makes Spray Foam Different?
Here’s a quick rundown of each insulation type:
🔹 Spray Foam Insulation
Spray-applied liquid that expands into foam, filling every gap for a full air seal.
- Open-cell: lightweight, great for soundproofing
- Closed-cell: denser, moisture-resistant, and adds structural strength
🔹 Fiberglass Insulation
The most common traditional option, made of fine glass fibers and typically installed in batts or rolls.
- Easy to install but leaves gaps
- Lower R-value per inch
- Can sag or settle over time
🔹 Cellulose Insulation
Made from recycled paper, treated for fire resistance, and blown into attics or wall cavities.
Can absorb moisture and settle
Eco-friendly and affordable
Good for hard-to-reach spaces
What Makes Spray Foam Stand Out?
While fiberglass and cellulose do a decent job of insulating, spray foam goes a step further by sealing the structure.
That means:
- No drafts or air leaks
- No moisture intrusion
- No loss of performance over time
It’s not just insulation—it’s a building envelope upgrade.
Is Spray Foam Worth the Higher Cost?
Let’s talk money…
While spray foam costs more upfront, it often pays for itself in energy savings, comfort, and resale value within just a few years.
When Is Spray Foam the Best Choice?
Spray foam is ideal for:
- Homeowners planning to stay long-term
- Whole-home renovations or new builds
- Sealing attics, crawlspaces, rim joists, and basements
- Hot, humid, or variable climates (Texas, Florida, Midwest)
Fiberglass and cellulose can still be good fits for quick upgrades or budget-limited projects—but they can’t match the performance of spray foam over time.
The Bottom Line
So, is spray foam insulation worth it?
Yes—if you’re thinking long-term.
You’ll get better comfort, better efficiency, and fewer future headaches. While fiberglass and cellulose are budget-friendly in the short term, spray foam offers the best return on investment when you look at the full picture.
