Cellulose vs. Fiberglass Insulation: Choosing the Right Fit for Your Home or Project

What Are They Made Of?
Cellulose Insulation

• Made from recycled paper products, usually newsprint
• Treated with borate to make it fire-resistant, insect-resistant, and mold-resistant

Fiberglass Insulation

• Made from tiny strands of glass fibers
• Often made with up to 30% recycled glass
• Naturally non-combustible

​
​Which One is Better?
Choose Cellulose if you want:

• Superior air sealing and soundproofing
• A more eco-friendly insulation
• A great attic retrofit material that fits irregular spaces well

Choose Fiberglass if you want:

• A budget-friendly option
• Better moisture resistance
• Non-combustible material for added fire safety

Final Thoughts
​Both are excellent insulators when installed properly. The choice often depends on:

• Your budget
• The area being insulated
• Moisture levels in your space (like attics vs. basements)
• Your energy efficiency goals
