The Mackinac Technology Company will develop an innovative, cost effective, retrofit window insulation system that will significantly reduce heat losses. The insulation system will use a durable window film that is highly transparent to visible light (more than 90% of light can pass through), but reflects thermal radiation back into the room and reduces heat loss in winter. The film will be microporous and breathable to allow air pressures to balance across the window system. The film will be bonded to a rigid frame that can be retrofitted to an existing single-pane glass window. Mackinac’s pane assembly will maintain a wrinkle-free appearance over an anticipated 20-year product lifecycle. The system will be fire resistant and lightweight (less than two pounds per square foot of window pane), which will help reduce stress on existing window panes.
If successful, Mackinac's window retrofit technology could save nearly one quad of energy if fully implemented across the U.S.
Increasing energy-efficiency is one of the easiest ways to reduce US reliance on energy imports.
The heating and cooling of buildings generates about 13% of the U.S. domestic greenhouse gas emissions. Through reduced building energy consumption, Mackinac’s retrofit system could help decrease these harmful emissions.
Mackinac’s window retrofit could be an inexpensive way to save on heating bills and improve indoor air quality and comfort.
