It makes absolute sense when you think about it. A large proportion of the heat from your radiators gets lost in the wall it is mounted on.
But not any more, because now you can reflect the heat and energy lost, back into the room.
Simple but brilliant, the Energy-saving Radiator Reflector Foil  is an earth-smart way to save energy around the house. The insulating foil helps keep those cold days at bay while reflecting the warmth from your radiators back into the room rather than losing energy through the walls.
Quick and easy to position, it can be cut to size and comes with fixing tape.
This form of insulation is especially important on outside walls where any heat loss will simply escape outside.
