By attaching the foil to the back of the radiator (and not the wall), the heat is reflected back into the room and isn't lost. Because the radiator heat is now used optimally, your room is heated much more efficiently. This saves energy, which is good for the environment and your wallet. You attach the foil to the back of the radiator with the included magnetic tape, not to the wall. Because the foil is on the back of the radiator, you won't see it from the room. The easiest way to do this is with a clothespin trick: First, clean the top and bottom of the radiator. Weight the foil with some clothes pegs and let the foil drop from the roll behind the radiator Once the foil is in place, secure the bottom with the magnetic strip and remove the bottom clothes pegs Then pull the foil tight upwards and also secure the top with a magnetic strip You can cut away any remaining edges with a knife Product specifications Radiator foil with magnetic tape - 500 x 50cm Item description Radiator foil with magnetic tape - 500 x 50cm Item number 8717853700316 Product type Foils Country of origin China Dimensions: 50 x 500 cm (total 2.5m²) Including 10 meters of magnetic tape.
