More than 80% of UK homes lose heat through the wall behind their radiators. Fitting these panels behind your radiator is fast and simple and will greatly reduce heat loss. Like all the best ideas it's a brilliantly simple concept - the highly reflective panels 'bounce' heat back into the room so you can enjoy the warmth rather than the wall heating up. This reduces the time it takes to warm up chilly rooms and the wider spread of heat virtually eliminates cold spots, making your radiators much more efficient.
