Founded in 1981 with the mission to provide its clients with an energy saving door, Nergeco entered the market with the customized Productivity Door. The high speed and short open/close cycle of this door helped conserve energy by reducing air exchange between rooms. Since then, Nergeco has continuously improved upon the product offering by introducing a soft-bottom edge to enhance safety. Nergeco continued its expansion by developing models suited to the specific needs of various industries, including food processing and clean room applications.

Interior High Performance Doors

Nergeco interior high performance doors are uniquely designed to help you cut energy spending by up to 30% at each opening / closing cycle. When closed, the flexible curtain fits securely in the customized sides of the structure creating a barrier between building sectors. During opening-closing cycles the flexible curtain gently slides upward ™just in time™ and then immediately slides down with the same speed but with less noise and wear due to the custom fit. Safety is ensured by the soft bottom edge that is flexible horizontally and vertically because it does not have a lower ballast bar.

Exterior High Performance Doors

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.
