Quiet Comfort: How Spray Foam Insulation Helps Soundproof Homes and Commercial Spaces

When most people think of insulation, they picture energy savings and temperature control. But spray foam insulation offers another powerful benefit that often goes overlooked: soundproofing. Whether you’re looking to quiet a home office or reduce noise transfer in a busy commercial building, spray foam delivers more than thermal protection. It helps create peaceful, productive spaces by reducing airborne and structural sound. 

At MY Insulation, we install high-performance spray foam across residential and commercial properties—and many of our clients are surprised by how much quieter their space becomes after the job is done. 

Spray Foam Sound Control in Homes and Businesses

In today’s world, background noise is everywhere. In homes, this might mean barking dogs, noisy HVAC systems, or teenagers with loud music upstairs. In commercial buildings, it could be foot traffic from adjacent units, echoing hallways or conversations between rooms. 

Uncontrolled noise doesn’t just distract—it can affect sleep, reduce productivity and even trigger stress. That’s where spray foam soundproofing becomes part of your building envelope strategy. And while no insulation can fully block all sound, spray foam insulation significantly dampens it, especially when compared to fibreglass or blown-in materials. 

How Spray Foam Insulation Reduces Noise 

Spray foam works differently than traditional insulation. When applied, it expands and hardens to fill every gap, crack and void—creating an airtight seal. This helps prevent the passage of sound waves through walls, floors and ceilings. 

There are two types of spray foam: open-cell and closed-cell. Open-cell spray foam is particularly effective for interior soundproofing because its soft, flexible texture absorbs more airborne noise, such as voices, TV sound or office chatter. Closed-cell foam also contributes to sound control, especially in walls that need both insulation and structural reinforcement. 

Combined with proper installation, spray foam provides both thermal and acoustic benefits, improving comfort on every level. 

Ideal Applications for Soundproofing with Spray Foam 

Spray foam insulation can be used in both new builds and retrofits across a wide range of settings. Here are just a few examples of how clients use it to reduce noise: 

Residential bedrooms and basements: Homeowners use spray foam to limit noise between floors and insulate basement suites. 

Home offices: As remote work continues, sound control in shared homes has become a high priority. 

Multi-unit housing: Property developers use spray foam to reduce sound transfer between condos or rental units. 

Retail spaces: Businesses want to isolate noise from neighbouring tenants in shared commercial buildings. 

Medical or wellness clinics: Privacy is essential in therapy and treatment spaces, and insulation plays a role in protecting confidentiality. 

Restaurants and cafés: Spray foam reduces echo and helps diners enjoy quieter, more comfortable environments. 

Bonus Benefits to Insulating with Spray Foam 

While soundproofing may be the main goal, clients also enjoy spray foam’s added value in terms of regulating indoor temperatures, reducing HVAC strain and sealing out allergens and pests. Whether you’re renovating a family home or building out a professional space, you’ll get more performance from every inch of your walls. 

Spray foam also contributes to energy savings and green building goals, supporting long-term sustainability and comfort.
