When you enhance the appearance of your home or office by covering unsightly radiators with custom-build radiator enclosures, you also increase your heating efficiency. Radiator enclosures direct warm air into the room – not to the ceiling or out back walls or windows – thus keeping a constant air flow which allows for consistency of temperatures. Not only do radiator enclosures provide an attractive alternative to ugly radiators, but they are also an energy-efficient means of dispersing heat. Tests by the University of Illinois have shown an increase in room temperature of 4½ °.
