EnerLogic™ Low-E Energy Saving Window Film All-Season Savings. Rapid Payback. Smart Investment.

EnerLogic™ low-e glass insulation technology revolutionises window film. A building can only be energy-efficient to the extent that its windows are energy-efficient. In summer, windows allow too much heat to enter, forcing cooling systems to work harder and making cooling costs climb. But in winter, they allow too much heat to escape, forcing heating systems to work harder and making heating costs climb.

Historically, most window films have provided only a summer solution - a solution for only part of the year. EnerLogic™ is different. It works year round - like other major energy saving measures such as high-efficiency lighting, new control systems, and HVAC upgrades. In summer, EnerLogic™ keeps the heat out, like traditional reflective window film. But in winter, EnerLogic™ does what reflective 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. And EnerLogic™ does this with outstanding optical clarity that's fully compatible with high-efficiency lighting. It looks great in any light.

How does EnerLogic™ Work?

EnerLogic's patent pending low-e coating redirects solar and radiant energy back to their source... for energy savings in every season! When 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 percent more insulating power to your window glass. Sunlight still enters, but harmful UV rays, discomforting heat and glare are substantially reduced. So while your building's occupants enjoy a whole new level of comfort, you enjoy a whole new level of savings. And it looks great with high efficiency lighting (low iridescence).



How Does EnerLogic™ Upgrade Windows?

Putting this unmatched insulating performance to work, EnerLogic™ is able to transform existing poorly-insulating windows into energy-efficient windows. The insulating power of EnerLogic gives single-glazed windows the annual insulating performance of double-glazed windows - and gives double-glazed windows triple-glazed performance. To get such improvement in performance from a thin, transparent window film is impressive - and much more affordable than window replacement.
