3. Indow Windows
Indow Windows are thermal window inserts that simply press into the inside of your window frames to give you money-saving, double-pane window performance, but at a fraction of the cost. As a bonus, they reduce the noise that comes through your windows by 50% and may dramatically reduce fog and condensation on your windows. Indow Windows were a finalist in the 2011 Cleantech Open National Business Competition.
