Select your siding type and watch these short install videos to see how RetroFoam is installed from the outside or the inside.
Vinyl and Aluminum Install Video
Whether your home has aluminum or vinyl siding, the process to install RetroFoam injection foam insulation is the same.
The installers will remove a row of siding around the entire home. Generally, a 2 ½-inch hole is drilled into each of the stud cavities, and the foam is injected. The installer will run the injection hose up to the top of the cavity and begin injection. Once they get to the middle of the cavity, they will then run the hose from the bottom to the middle. This method ensures the cavity is completely filled.
Once the injection process is complete, the holes drilled into the sheathing are plugged, and the siding is replaced.

Brick Install Video
The insulating brick exterior process is obviously different from other siding materials as it doesn’t make sense to remove brick to gain access to the wall cavity.
In this installation process, three 5/8-inch holes are drilled into the mortar to reach the wall cavity. A hole is drilled at the top, middle, and bottom. This ensures the foam is injected into the cavity and completely fills it.
Once the foam has been installed, the holes are filled with mortar.

Wood Install Video
The condition of the wood siding will decide how the installation of the injection foam is done.
If the wood is in good condition, it can be removed, and the holes would be drilled into the sheathing underneath. Once the installation is complete, the holes are plugged, and the wood siding is replaced.
If the wood is brittle, there is the chance it could break, so it makes more sense to just drill through it.
In both cases, the actual injecting of the foam is the same as vinyl or aluminum siding – the hose is run from the top to the bottom to ensure the foam completely fills the cavity.

Block Install Video
The installation process for concrete block walls involves drilling holes into the middle of the wall to access the cores.
The bricks' cores are lined up, so once the holes are drilled, injecting the foam fills those, as well as any other nooks and crannies.
Once the cores and openings are filled, the holes are filled with mortar.

Stucco Install Video
When insulating homes with stucco siding, three 5/8-inch holes are drilled at the top, middle, and bottom of each cavity.
This method ensures the wall cavity is completely filled with foam.
After the holes have been drilled, the foam is injected into the wall through each hole. Once the job is done, the holes are filled with mortar.

Drywall Install Video
When installing RetroFoam from the inside, the prep is vital as you don't want to have drywall dust all over everything.
Your installer will make sure all surfaces and items in the area of the home where the injection foam will be installed are covered in plastic.
Once everything is covered, the installer will do a chalk line on the walls and drill the holes centered on that line.
The installer then runs the hose up to the top of the cavity and begins injecting the foam. The hose is run from the top to the middle and from the bottom up to ensure the cavity is full.
Once the foam has been installed, the holes are plugged, and a rough patch of drywall mud is applied.
