Spray Foam vs Fiberglass Insulation

When it comes to insulating your home, two of the most popular choices are spray foam and fiberglass. Both have their pros and cons, but which one is right for you?

R-Value Comparison

Spray Foam (Closed Cell) has an R-value of about R-6.5 to R-7 per inch. It provides a superior air seal and adds structural integrity to your walls.

Fiberglass typically has an R-value of R-3.5 to R-4 per inch. While cheaper, it allows for air leakage if not installed perfectly.

Cost

• Fiberglass: The budget-friendly option.
• Spray Foam: Higher upfront cost, but significant long-term energy savings.

Longevity

Spray foam can last 80+ years without settling. Fiberglass tends to settle over time, reducing its effectiveness.

Conclusion

If budget is your primary concern, fiberglass is a solid choice. However, for maximum energy efficiency and longevity, spray foam is the clear winner.
