RetroFoam FAQs

Questions? We have answers.

Will the interior drywall bow, crack or pop during installation?

Although this is rare, it is possible.

Our installers go through rigorous training to ensure the wall cavity is filled with injection foam insulation. This special training includes checking for obstructions in the wall, running the injection hose from the top down to the middle and from the bottom up, as well as listening to the sound of the hose as the foam is injected.  It’s important to share any areas of concern with the PHI team so everyone is on the same page before the install takes place.

Can you run wires through your walls after RetroFoam is installed?


The foam is very soft and pliable, which makes it easy to fish wires through it. So, if you want to add an outlet or change a light switch, you won’t have any problems.

How do installers know when the wall cavity is full?

Early on in the installation process, the installer makes sure that the wall cavity is accessible from the bottom to the top.

During the actual installation, the installer runs the hose for the injection foam from the top of the cavity to the bottom, ensuring it is completely filled.

Can I insulate just one problem wall?

You definitely can, but there’s a catch.

It’s always important to approach your home as an entire system. If you only insulate one wall, you probably won’t see the results you’re hoping for.

Does RetroFoam insulation work for sound deadening?

Yes, RetroFoam can help make a home a little quieter, but that’s not what it’s designed to do.

If you’re looking to make your home quieter or completely soundproof a room, you might want to look at options specifically made for that.
