Low-E Storm Windows
Low-E stands for low-emissivity. It is an extremely durable coating on glass that minimizes the amount of infrared energy that can pass through, without compromising the amount of visible light that shines in. Low-E storm windows are less than half the cost of full window replacement, and can be installed without the help of a contractor. Plus, you can get 25% off Low-E storm windows at participating retail locations.
