Do Your Existing Walls Need Updated Insulation?

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 spaces, and rim joist, while injection foam is best suited for enclosed existing walls.

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.

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.

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.

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 reason why this happens, including previous damage to the drywall or the drywall wasn’t installed properly.
