Insulation That Works Inside Your Existing Walls

Many older and existing homes have wall cavities with little or no insulation. This can allow heat to move more easily through exterior walls, making indoor temperatures harder to maintain throughout the year. Injection foam wall insulation is designed to add insulation inside suitable existing wall cavities without requiring the complete removal of interior walls.

The installation process involves accessing the wall cavities through carefully placed openings and injecting insulation into the available space. The result can help reduce heat loss during colder months and limit heat gain during warmer weather. Every home is different, so wall construction, existing insulation, accessibility, and other conditions are considered when determining whether injection foam insulation is suitable.

Why Homeowners Consider Injection Foam Insulation

Adding insulation to suitable wall cavities can help address common comfort and energy-efficiency concerns in existing homes.

Improved Indoor Comfort

Insulation helps slow heat transfer through exterior walls, which can support more consistent indoor temperatures throughout the year.

Suitable for Existing Homes

Injection foam can be installed in suitable existing wall cavities without requiring the complete removal of interior drywall.

Reduced Heat Transfer

By adding insulation inside exterior walls, the material can help reduce heat loss in winter and limit heat gain during warmer weather.

Hard-to-Reach Wall Cavities

Injection insulation provides a way to add insulation to enclosed wall cavities that may otherwise be difficult to access during a standard home renovation.

How the Process Works

How Injection Foam Wall Insulation Works

Home and wall assessment

We inspect the exterior walls and review the home's construction to determine whether the existing wall cavities are suitable for injection foam insulation.

Access points are prepared

Small access openings are carefully made in the appropriate areas of the exterior wall. These openings provide access to the enclosed wall cavities without removing the interior drywall.

Foam is injected into the wall cavities

Injection foam is introduced into the wall cavities through the prepared access points. The material fills available spaces and adds insulation between the interior and exterior sides of the wall.

Openings are sealed and the area is checked

Once the insulation work is complete, the access openings are sealed and the work area is cleaned. The completed installation is checked to ensure the wall sections have been properly addressed.

 Trustindex verifies that the original source of the review is Google. The Cozy Walls team was an absolute pleasure to work with. I have an older home that was originally built in the early 1900’s. It was drafty and I could hear a lot of road noise from inside my living room. That is until Cozy Walls did their thing. The noise reduction was the first thing I noticed. I couldn’t believe the difference. Erik was very informative and the Veteran Discount helped a lot! Definitely worth the cost as I’m already noticing a difference in my energy bill. Highly recommend!

 Trustindex verifies that the original source of the review is Google. Me and my wife just bought our first house and discovered that our bedroom was very cold compared to the rest of the house, and that our furnace was almost constantly running struggling to keep the house warm. Cozy Walls came out and insulated the entire house and garage and found out that most of our walls had no insulation anymore due to the age and the insulation deteriorating. Since having work done our bedroom is much warmer and our furnace runs a lot less, saving us money! Amy and Zach run a great business and their crew was very professional. And it was very affordable and cost-effective. They placed blankets over my motorcycles in the garage so they wouldn't get dirty during the work being performed and they cleaned up everything very well after. Cannot recommend Cozy Walls enough if you need any insulation done in your house

 Trustindex verifies that the original source of the review is Google. WELL worth the read! Customer service ?  This company is right on point! From Zack and Amy to the rest of their team, wow! Until I found these two companies, I had an awful and long time getting one to return my calls or come out for an estimate. I saw an ad on TV for Healthy Home Insulation, left a message on a Sunday, they came out the next day! Before Erik left he gave me an estimate for attic and basement (Healthy Homes) as well the walls from (Cozy Walls Insulation.) They were out here the following week to complete the job! I have HORRIBLE allergies that can cause my eyes to swell shut to causing vertigo. I was concerned that the smell of foam spray would be an issue. Amy, Cozy Walls said they would come out try a wall see how it went. If it was ok, complete the job, if not, we would figure something out. To me this is a company that truly cares about their customers! BOTH companies have gone above and beyond from start to finish. I would recommend them to anyone!

The project time depends on the size of the home, the number of walls being insulated, wall construction, and accessibility. The exact installation time is determined after the property has been assessed.

Can injection foam insulation help reduce heating and cooling costs?

Adding insulation can reduce heat transfer through exterior walls. This may help reduce heat loss during colder weather and heat gain during warmer weather, although energy savings vary based on the home’s existing insulation, HVAC system, air leakage, climate, and energy use.
