Are you tired of uncomfortable rooms, drafts, cold walls, and high energy bills?

If you answered yes to any of these questions, the injection foam insulation we offer for existing walls can help.

RetroFoam insulation can make your home quieter, stop those annoying drafts, and lowers your monthly energy bills.

Our injection foam has a superior R-Value and creates an air barrier while filling all of the gaps and cracks in the wall. It is customized to handle every area of your home’s walls, including those hard-to-reach areas in a framed out wall section, like octagonal and angle walls with tight corners.

RetroFoam stops airflow into the wall cavity space, creating a home that is more comfortable and energy-efficient. Best of all, the injection foam installation can be done with little intrusion to the house and is typically done from the outside.

Soon the benefits start rolling in — sound and noise reductions, a draft-free lifestyle, and lower energy bills.

Benefits of RetroFoam

RetroFoam Install Process

  1. A strip of siding is removed from around the house. This process can vary depending on the home’s exterior.

  2. Holes are drilled into each wall cavity, and the installer checks for obstructions. If the home has a brick exterior, three holes are drilled — one at the top, one in the middle, and one at the bottom.

  3. The RetroFoam insulation is injected into each of the wall cavities. The installer has been specifically trained to ensure the cavity is completely filled.

  4. The drilled holes are plugged, the siding is replaced, and the project is cleaned up.

Our Homeowners Say

Had a great experience with Indiana Spray Foam. They were on time, preformed their task in a timely matter, and cleaned up the mess. When they left you could not even tell they had been here and insulated the walls of our home. They will be back soon to do the the attic. Thank you!

RetroFoam FAQs

Yes, you can.
RetroFoam insulation is a very pliable material. Fishing new electrical wiring through the injection foam insulation isn’t a problem at all.

While rare, it is possible that the RetroFoam installation could cause your drywall to pop or crack.
There are a few reasons why this happens, including previous damage to the drywall or the drywall wasn’t installed properly.

RetroFoam installers have been specially trained on how to properly insulate walls to ensure they are completely filled.
This training includes checking for obstructions in the wall, timing, and techniques like injecting from the top to the middle and from the bottom to the middle of the cavity.

The difference between injection foam insulation and spray foam insulation is how the two are installed.
Spray foam is sprayed into open cavities in the attic, exposed walls, crawl space, and rim joist, while injection foam is best suited for enclosed existing walls.

The installation process varies depending on the exterior of your home.
If your home has aluminum or vinyl siding, then a row of siding can be removed. In some cases, the same is true for wood, but if the wood isn’t in great condition, it might make more sense to drill through it.
If the exterior is brick, then instead of the one drilled hole in each stud cavity, there are three holes drilled into the mortar — one at the top, one in the middle, and one at the bottom.
We will go through the installation process for your specific project at the time of your quote.

For the average home, the installation of RetroFoam takes less than a day.
The size of your home plays an important part when determining how long the installation will take. For example, a larger house will take longer than a smaller home.
