Về công ty
ESS has been extremely rewarding for all of us concerned with energy conservation and Their business. In 2002, ESS Energy Product, Inc. (then Energy Sentry Solutions, Inc.) introduced a new product offering to insulate and seal attic pull down ladders. While there were a number of existing products already available, the ESS kit (called the Energy Guardian® and the subject of a pending patent application) had some unique characteristics which have come to distinguish it from any other alternatives. First, the kit offered a revolutionary air seal with a seemingly simple new and innovative art form - the lip of the lid fit into the frame of the kit to form a revolutionary air seal.
