If your home uses a radiator as a heat source, then you likely know how expensive heating during the winter can get. But, aluminum can help your radiator be more efficient and help you save on your heating bill during the winter. To do so, mount some foil to the sides of your radiator and behind it in order to reflect heat away from your walls.
The heat will be concentrated back towards the center of your room and towards your radiator, meaning more efficiency and less heat loss. The end result is also cheaper heating bills.
