RetroFoam injection foam insulation is an excellent solution for enhancing the comfort and energy efficiency of homes or commercial buildings with concrete block walls. The installation process is straightforward yet highly effective. Our team begins by drilling ⅝-inch holes into the middle of the wall to access the empty cores within the concrete blocks. These cores, which allow unwanted airflow, are then filled with the foam insulation. For taller walls, additional holes are drilled at the top to ensure complete coverage.

Once injected, the foam expands to fill not only the cores but also any tiny crevices or gaps left during the construction of the walls. This process creates a robust air seal that prevents air leakage, keeping your indoor spaces more comfortable and reducing energy costs. After the foam is in place, the drilled holes are neatly sealed with mortar, leaving your walls well-insulated and visually intact.



By choosing RetroFoam for your concrete walls, you’re investing in a long-term solution that improves your building’s insulation, enhances comfort, and boosts energy efficiency.
