Fiberglass vs Cellulose Insulation

When it comes to attic insulation, fiberglass and cellulose remain two of the most popular choices. Both materials are efficient, cost-effective, and widely available—but they differ in composition, performance, and environmental impact.

Fiberglass insulation in Wichita KS is made from fine glass fibers and typically comes in batts or loose-fill form. It’s lightweight, non-combustible, and resistant to mold. Cellulose, on the other hand, is made from recycled paper products treated with fire retardants, offering excellent sustainability and sound absorption.

Comparing Performance and Value

According to Sustainability research, cellulose has an edge in eco-friendliness due to its high recycled content. It also provides better air sealing when densely packed, reducing drafts and improving efficiency. However, fiberglass retains its shape longer and resists settling over time.

Both materials offer similar R-values, but cellulose tends to perform slightly better in blocking air leaks. For homeowners prioritizing environmental impact, cellulose is the greener option. For those focused on durability and affordability, fiberglass remains a dependable and long-lasting solution. Choosing between the two depends on your home’s needs, budget, and performance goals.
