How is RetroFoam Insulation Installed in Walls with Stucco Exterior? (Quick Answer)
When working with a stucco exterior, RetroFoam installers drill three 5/8-inch holes at the top, middle, and bottom of each wall cavity. The foam is injected into the holes, and once they are all filled, the holes are filled with mortar.
Now let’s get into the gist of how RetroFoam insulation is installed when a home has a stucco exterior.
Your exterior walls can be a significant pain point in your home’s comfort and energy efficiency, so updating your exterior wall insulation is a great fix.
Here’s your lingering question – How is RetroFoam insulation installed in exterior walls with a stucco exterior?
This article will explain in detail how injecting foam insulation into existing walls with a stucco exterior is done.
RetroFoam Injectable Insulation for Existing Homes with Stucco Exterior
The process of installing RetroFoam home insulation to exterior stucco walls is very similar to how it’s done for brick.
Three 5/8-inch holes are drilled at the top, middle, and bottom of each wall cavity. This is done so the installer can make sure the foam completely fills the cavity.
After the foam has been injected into each cavity, the drilled holes are filled with mortar. The installer uses mortar because it can give your exterior the same texture where the holes were drilled as the stucco.
If you would prefer not to have the installer drill into your stucco, you do have the option to have the RetroFoam installed from the inside.
