In summer, EnerLogic keeps the heat out, like traditional reflective window film. But in winter, EnerLogic does what reflective window film can't do: It locks the heat inside. So you get a perfect balance of energy efficiency, comfort and cost savings - all year long. Other window film technologies can help you save energy. But because EnerLogic's patent-pending coating delivers maximum energy efficiency in every season, no other window film can match its annual dollar savings.

When the window film is professionally applied to the inside surface of your existing windows as a microthin, ultra-powerful low-e window film, EnerLogic adds as much as 92% more insulating power to your window glass. Sunlight still enters, but harmful UV rays, discomforting heat and glare are substantially reduced.
