Soundproofing is a major concern for homeowners and business owners in Huffman, AK, where external noise from traffic, weather, and nearby activities can disrupt comfort and productivity. Spray foam insulation has gained popularity as a solution for sound control, but not all types of spray foam are equal. The debate between open-cell and closed-cell spray foam often centers around their effectiveness in reducing noise. In this guide, we’ll explore how each type performs, helping you make the right choice for your property.
Spray foam insulation is a versatile material used to improve energy efficiency, reduce air leakage, and enhance soundproofing. It comes in two main types:
Both types offer benefits, but their soundproofing capabilities vary significantly.
Before comparing open-cell and closed-cell spray foam, it’s essential to understand how soundproofing works. Sound travels in waves and can penetrate walls, floors, and ceilings through air gaps and vibrations. Effective soundproofing materials achieve the following:
Spray foam contributes to soundproofing by sealing air leaks, dampening vibrations, and adding mass to walls or ceilings.
Open-cell spray foam is highly effective at absorbing airborne sounds, such as voices, music, and television noise. Its porous structure allows it to trap sound waves, preventing them from bouncing off hard surfaces. This makes it an ideal choice for:
However, open-cell spray foam is less effective at blocking low-frequency sounds (such as heavy machinery noise) because it lacks the density to prevent sound waves from traveling through walls completely.
While closed-cell spray foam does help with noise reduction, it primarily functions as a sound blocker rather than an absorber. It prevents sound transmission by adding mass to walls and ceilings, making it useful in:
Because of its density, closed-cell spray foam does not absorb sound as well as open-cell foam. Instead, it helps by reinforcing structures and reducing the resonance of sound through walls.
The answer depends on the type of noise you’re trying to reduce:
| Feature | Open-Cell Spray Foam | Closed-Cell Spray Foam |
| Sound Absorption | High | Low |
| Sound Blocking | Moderate | High |
| Best For | Airborne Noise | Structural Noise |
| Density | Low | High |
If your goal is to absorb sound inside a room and reduce echo, open-cell spray foam is the better choice. If you need to block external noise and add insulation, closed-cell spray foam is more effective.
If you live in a quiet residential neighborhood and need to minimize indoor noise transfer, open-cell spray foam is an excellent option. However, if you live near a busy road, industrial site, or experience extreme weather, closed-cell spray foam may provide better results.
For optimal soundproofing, some professionals recommend combining both types—using open-cell spray foam for interior walls and closed-cell spray foam for exterior walls and ceilings.

Spray foam insulation significantly reduces noise levels but does not eliminate all sounds. It absorbs and dampens sound waves, making spaces quieter but not entirely soundproof.
Yes! Many homeowners and businesses use open-cell foam for interior walls and closed-cell foam for exterior walls to achieve a balanced soundproofing effect.
No, open-cell spray foam is not waterproof. It is more breathable and allows moisture to pass through, which is why it’s not recommended for moisture-prone areas.
Yes, closed-cell spray foam has a higher R-value and provides excellent thermal insulation, helping to reduce energy costs and improve indoor comfort.
Spray foam insulation can last 20-30 years or more with proper installation, providing long-term soundproofing and energy efficiency benefits.
Yes, once fully cured, spray foam insulation is safe and does not release harmful chemicals. However, professional installation is recommended to ensure safety during application.
The cost varies based on the type of spray foam, the size of the project, and installation complexity. Contact Turnagain Spray Foam for a personalized quote.
Yes, spray foam can be injected into existing walls, but the process may require cutting small access holes for proper application.
