Nergeco exterior high performance doors are uniquely designed to help you cut energy spending by up to 30% at each opening / closing cycle. Because most cold air is lost when the door is open, Nergeco doors are designed to open ™just in time™ and close at the same high speed, minimizing open time. When closed, conduction through the door can be reduced with a double layer curtain fitted with insulation inserts. To resist high winds, the patented Trekking curtain has horizontal stiffeners that distribute wind resistance uniformly over the whole structure.
