What is the difference between fiberglass and cellulose insulation?

Fiberglass insulation is composed of fine glass fibers and is usually available in batts or blown-in form. In contrast, cellulose insulation is made from recycled paper that has been treated for fire resistance. While cellulose tends to have better density, fiberglass is more moisture-resistant and requires less maintenance over time.

Which is better: fiberglass or cellulose insulation?

The choice between fiberglass and cellulose insulation depends on your specific goals. Fiberglass is generally more affordable and widely used, while cellulose offers superior coverage and air resistance. Both types allow for air movement, so additional air sealing may be necessary for maximum efficiency.

Is fiberglass insulation cheaper than cellulose?

Yes, fiberglass insulation is typically the most budget-friendly option for attic insulation. Cellulose usually costs a bit more due to its higher material density and installation requirements.

Does cellulose insulation settle over time?

Yes, cellulose insulation can settle and compress over time, which may reduce its effectiveness. This settling can necessitate the addition of more material to maintain proper coverage.

Is fiberglass insulation affected by moisture?

Fiberglass does not absorb moisture like cellulose, but it can lose effectiveness if it becomes wet or is improperly installed. Managing moisture is crucial for both types of insulation.

Which insulation is better for attics?

Both fiberglass and cellulose are commonly used in attics. Fiberglass is ideal for cost-effective upgrades, while cellulose can provide better coverage in irregular spaces. However, neither provides full air sealing without additional measures.

Do fiberglass or cellulose insulation stop air leaks?

No. Both fiberglass and cellulose insulation slow heat transfer but do not fully stop air movement. Proper air sealing is required to prevent energy loss and drafts.

Which insulation is better for humid climates like Texas?

Fiberglass is generally more resistant to moisture issues, while cellulose can absorb moisture and potentially lead to mold or deterioration in humid environments.

How long do fiberglass and cellulose insulation last?

Fiberglass insulation can last 10–15+ years, while cellulose may require maintenance sooner due to settling and moisture exposure.

Can fiberglass or cellulose insulation lower energy bills?

Yes, both insulation types help reduce heat transfer and improve energy efficiency. However, performance depends heavily on proper installation and air sealing.
