The Soundproofing Benefits of Spray Foam

Whether they are commercial insulation for a quiet home to sleep or study, or simply want a space free of distractions, many homeowners will choose to invest in spray foam insulation. Not only does it provide superior thermal insulation, but it also helps block out noise. However, not all insulation can be used for soundproofing, and different types of insulation offer different benefits. Open-cell spray foam is better at reducing noise, while closed-cell offers more of a barrier to reduce airborne and impact noise.

Both types of spray foam reduce noise by blocking cracks and gaps where sound can travel. They also work to absorb and reverberate sounds, which helps minimize noise transmission between rooms. However, the key to soundproofing with spray foam is in proper installation.

Closed-Cell Spray Foam

Closed-cell spray foam creates a dense, rigid barrier when applied to walls, floors, and ceilings. This prevents airflow, which minimizes airborne noise such as music, television, and voices. It also blocks impact noise from footsteps and large appliances.

Open-Cell Spray Foam

The softer, more porous nature of open-cell foam makes it better at absorbing and reverberating sound waves, which reduces the amount of noise transmitted through walls. This allows it to have an STC rating of up to 35 or 40, which significantly reduces the amount of sound that can be transferred through a wall. This is why it is the most popular option for soundproofing in homes.
