Energy Saving Window Film For Winter

November 8, 2012 | 7 comments

It’s almost energy saving season. That time of year when winter’s icy chill can make the temperatures drop and your heating bill skyrocket. But here’s an energy saving tip to keep you and your home from succumbing to the energy-robbing cold. You can add energy savings with EnerLogic® window film that helps insulate your home to keep more of your money from flying out the window.

Ways to save energy for less
A few tips on saving energy at home include simple things such as making sure your furnace has a clean air filter, installing weather stripping or caulking to reduce cold air leaking into your home, and programming your thermostat to a lower temperature while you’re away and at night. But once you get beyond those, many energy saving tips include more expensive options such as installing a more efficient furnace, adding insulation to your attic or crawl space, or replacing windows.

The latter targets one of the major sources of heat loss in your home – your windows. Windows typically account for 25 percent of annual heating and cooling costs, but they can account for as much as 40 percent. However, there are ways to save energy with your windows without the major cost of replacing them. Installing EnerLogic window film to your home improves the efficiency of your windows and can be a more cost effective energy saving option.

How does EnerLogic deliver energy savings?

Like most window films, EnerLogic blocks harmful UV rays (99%) and reflects solar energy to protect your house and keep it cool in the summer. But standard solar-control window films can have negative effects in the winter when you want to keep your house warmer. They block the sun’s warming rays from coming into your home and do nothing to keep the heat in. This is where EnerLogic stands out from the crowd as a year-round energy saving product. EnerLogic window film acts as an insulator that directs radiant heat back into your home to keep more of it and your money from flying out the window.

EnerLogic contains a special low-e coating that can add up to 92 percent more insulating power to the glass in your windows. From an efficiency standpoint, that essentially transforms your single-pane windows into double-pane windows without the sizeable cost of new windows. It also delivers savings to your monthly heating bill and helps lower cooling costs in summer too.

How to save energy at home

Improving your house’s efficiency is as easy as finding your nearest EnerLogic dealer. They’ll come to your home to conduct a free energy audit and can professionally install EnerLogic window film to upgrade your home’s energy savings all year long.

Winter is almost here. That means it’s time to forget about energy saving tips with ridiculously high price tags, and go with EnerLogic – the cost effective solution to increase your home’s energy savings in the summer and the winter for years to come.

    So, if I read this correctly, EnerLogic 70 blocks sunlight in the summer to help keep the room cool. Then, in winter, the film effectively increases the E value of the glass to reflect back into the room the heat loss from the room and its contents. Here’s where I get lost. In winter, is the film still reflecting the sunlight and thus reducing warming sunlight from entering the room? a) If it reflects infrared during summers only, that’ really something. b) If it reduces winter heating, what’s the NET gain from (summer savings) + (higher E values savings) – (the loss from free winter heating)?

    Hopefully this explanation will help: In the winter, the film does reflect a certain amount of the sunlight, preventing the free solar heat from entering the home/building. But it does this only for 3-4 hours per day per exposure. And in winter, there tends to be more cloudy days. But the improvement in the insulating value, from adding the VEP film, enables saving heating energy 24 hours a day, 7 days a week in winter. This additional number of hours of improvement usually overshadows the loss of free solar heat, thus providing a net heating savings. Typically, the savings are 5-10% of annual heating costs, and vary based on location, energy rates, amount and type of glass, and presence of overhangs.

    It has been my experience with window films that you can feel the heat on the windows. In fact, I would say they feel hot to the touch, but for whatever reason doesn’t seem to radiate into the house. In the summer, we have found a reduction in cooling from about $260/month to $180/month. Obviously this will likely change depending on where you live, but we found it highly effective. In the winter, we had even better results. We have electric baseboard heat, so anything that helps keep heat from escaping helps since there is no quick way to heat. Two years ago without the film, we were running around $300/month during the January/February months. This year with the -20 temps and a colder than normal winter our most expensive bill has been $225. Again, our home is all electric so it is likely a larger difference than looking at heat bills alone. But we have begun doing all windows including the north facing since it seems to make such an impact in the winter.

    Greg, glad you’re seeing these great year-round results with window film!

    Hey Vista team – Great post. How long have you been using the EnerLogic film? Is this primarily for residential windows or could you also use it on commercial projects? We’re obviously in a part of the country that sees a lot of sunlight and heat, therefore we are always looking for better films with energy-saving capabilities. This sounds like it could be a nice fit.

    Would love to learn more. Feel free to reach out, info @ Thanks!

    Hi Jaclyn, EnerLogic is definitely suited for commercial projects as well. It’s been used on commercial buildings across the country (most recently, we just watched it save a high-rise hotel 23% in cooling costs and 25% in heating costs annually after application!). We will get more information out to you soon!

    These incredible performers block out everything except your view, preventing up to 79% of solar heat from entering your home or workplace through the glass. This means a buildings energy efficiency can be improved to deliver annual energy savings of up to 35%*. The films also cut glare by up to 92% and block a remarkable 98% of hsarmful UV rays.
