Q: Can spray foam insulation reduce noise?
Yes! While it’s not classified as soundproofing, closed-cell and open-cell spray foam significantly reduce airborne noise like traffic, voices, and even barking dogs.
Q: How does it block sound?
Spray foam fills cracks, gaps, and cavities — reducing the space sound travels through. Open-cell foam is especially effective at absorbing sound waves.
Q: Is spray foam better than traditional insulation for noise?
Traditional fiberglass insulation does little to reduce sound. Spray foam provides both thermal and acoustic benefits in one application.
Q: Where should I apply it for the best sound dampening?
Great spots include between interior walls, in attic spaces, or around noisy utility rooms like laundry areas or home gyms.
