This means that these historical pieces of cast iron will not end up in a landfill-they will get to live on elsewhere, protecting another family for generations! Using firebacks protect both our hearths and our planet by reducing harmful emissions caused when heat escapes through chimneys. It saves energy since it reflects heat back into the room instead of out into the sky. A lot of people don’t know this but even open fires contribute significantly to air pollution so every little bit helps towards making your home safer for your family while also being better for the environment.
