Transform Your Home by Insulating Existing Walls with RetroFoam Injection Foam
Old cellulose and fiberglass in exterior walls are not good enough to stop airflow in your home.
If you have no insulation, it's worse -- nothing will stop that air from getting in or heat from getting out.
Injection foam insulation creates an air seal that will stop air movement. Stopping that air leakage can make a huge difference in the comfort of your home, as well as the energy efficiency.
