Compare cellulose vs. fiberglass insulation for attics, walls, and existing homes. Discover the best option for comfort and energy efficiency in NYC.
Which Insulation Is Right for Your Home or Building?
Choosing the right insulation can make a significant difference in your home’s comfort, energy costs, and indoor air quality. At Spray Foam Insulation NYC, we install both cellulose insulation and fiberglass insulation, helping homeowners, builders, and property managers select the best solution for their project.
Whether you’re insulating an attic, walls, ceilings, or an existing home, understanding the differences between these two insulation types is the first step toward making an informed decision.
How Spray Foam Insulation Works?
Spray foam is typically applied within the cavities of your home. It forms a continuous barrier on the surface it is applied to. The foam is typically stored as two separate chemicals and is mixed onsite as it’s applied.
Cellulose insulation is a premium loose-fill insulation made primarily from recycled paper fibers treated with fire-resistant minerals.
✔ Excellent thermal performance
✔ Superior sound reduction
✔ Dense installation that fills gaps and voids
✔ Helps reduce unwanted air movement
✔ Environmentally friendly with high recycled content
✔ Ideal for attic upgrades and existing wall cavities
✔ Great choice for retrofit insulation projects
Cellulose conforms around wiring, plumbing, and irregular framing better than fiberglass, making it an excellent solution for many older homes throughout New York City, Long Island, and New Jersey.
Fiberglass insulation remains one of the most common insulation materials due to its affordability and versatility.
✔ Budget-friendly
✔ Proven thermal insulation
✔ Lightweight material
✔ Naturally non-combustible
✔ Excellent for new construction
✔ Available in batts and blown-in applications
Fiberglass performs best when installed correctly with minimal gaps or compression.
Overall, hiring a professional spray foam insulation service contractor can help ensure that your insulation is installed correctly and efficiently, providing long-lasting benefits such as improved energy efficiency, reduced noise levels, and better moisture control.
We uphold the highest standards in all our projects to ensure our clients are happy with what we deliver.
For most attic upgrades and retrofit insulation projects, cellulose insulation offers better overall performance.
