🏡 What's the Difference Between Fiberglass Insulation and Spray Foam?
Not all insulation works the same way.
🔹 Fiberglass Insulation
• Slows heat transfer
• Can leave gaps and air leaks
• May lose effectiveness if compressed or exposed to moisture
🔹 Spray Foam Insulation
• Insulates AND air seals in one application
• Expands to fill cracks, gaps, and hard-to-reach areas
• Helps reduce drafts and moisture intrusion
• Can improve energy efficiency and indoor comfort
Many homeowners are surprised to learn that air leaks—not just a lack of insulation—are a major cause of energy loss in a home.
If you're building a new home, finishing a shop, insulating a pole barn, or upgrading existing insulation, spray foam may be worth considering.
