Spray Foam vs. Traditional Fiberglass Insulation: Douget's Explains the Difference
“Both types of insulation have been used successfully for a long time, but spray foam gives you that added air seal,” said Joel Douget. “You’re filling those little cracks and gaps that traditional insulation may not seal, and that can make a real difference in how comfortable the building feels.”
Douget’s explains the differences between spray foam and traditional fiberglass insulation and why air sealing matters for Texas homes and businesses.

MADISONVILLE, TX – If you’re looking at insulation for a home or commercial property, you’ve probably come across two familiar options: fiberglass and spray foam. Douget’s Spray On Spray Foam Insulation LLC explains what separates the two and why more people may want to take a closer look at spray foam.

Fiberglass has been around for decades, and there’s a reason it’s still widely used. It slows down heat transfer and, when installed correctly, can do a good job insulating a building. You’ll typically find it in batts, rolls, or loose-fill insulation.

Spray foam does more than that. It’s applied as a liquid and quickly expands, allowing it to get into cracks, gaps, and tight spaces that can be difficult to seal with traditional insulation.

That’s where the biggest difference comes in. Fiberglass helps slow heat transfer, but it doesn’t necessarily stop air from moving through small gaps around a building. Spray foam helps insulate while sealing those gaps at the same time.

“Both types of insulation have been used successfully for a long time, but spray foam gives you that added air seal,” said Joel Douget. “You’re filling those little cracks and gaps that traditional insulation may not seal, and that can make a real difference in how comfortable the building feels.”

In Texas, that’s worth paying attention to. When it’s hot outside and the AC is running, you don’t want cooled air finding its way out through cracks and gaps. A tighter building can help keep temperatures more consistent and make it easier to stay comfortable.
