Energy-saving door solutions /Global/Sustainability/photos/Energy-saving-door-solutions524x224.jpg ASSA ABLOY Americas is leading the way in energy-efficient door opening solutions. When ASSA ABLOY Americas division started to create its Green door solutions it already had a number of energy-efficient products in its product portfolio that could be certified under LEED (the Leadership in Energy and Environmental Design Green Building Rating System, developed by the US Green Building Council). Some were originally developed for cold weather in Alaska and have a high level of thermal resistance. Stacey Callahan, Director of Marketing and Innovation for the Door Group in the Americas Division in the USA, says: “Using these products saves energy in any building; they are just as useful in a warm climate where you want to keep the heat out and the cool air-conditioning in.” Callahan says the division is continuing to develop Green and energy-efficient products. Maiman’s Thermal Fused Flush doors are made from 75 percent recycled material. Ceco’s metal doors are constructed using a high percentage of scrap steel and other recycled material. The TRIO steel-stiffened hollow metal door from Ceco Door and Curries is filled with polyurethane foam, which expands to fill the core, eliminating air pockets that could allow thermal leakage. The Trinity door-closer from Norton Door Control needs no batteries or power wiring. Any movement of the door of 10 percent or more is enough to generate the necessary power for closing.
