Save Money, Stop the Cold. And Enjoy Improved Comfort.

Windows are the major source of heat loss in your home. The next cold night, put one hand on a window and the other hand on the wall – you will literally feel the difference. In fact, as much as ONE THIRD[1] of the heat in your house can leak out of poorly insulated windows.

When heat escapes — or when it is allowed in during the summer — your furnace or air conditioner has to work that much harder to keep the temperature inside your house comfortable and consistent. Drafts contribute to your discomfort.

If you’ve done any shopping at all, you know that windows can be really expensive to replace, especially if you try to replace all of them at once! And if you have historic or handcrafted windows, replacing them will be even more costly.

WindowSkin™ is the easy, affordable solution to all these problems.

Simple to mount, this lightweight, custom-fit window insulation system looks great and works great too. Just press the WindowSkin™ on to your existing window to add an extra layer of efficiency and comfort. It’ll keep the heat in and the cold out all winter long and in summer, it’ll keep the heat outside and the cool air conditioning inside with no messy films or damaging tapes to hassle with. Best of all, WindowSkin™ is nearly invisible and doesn’t interfere with the use of your windows or window treatments.

All you need to do is install a WindowSkin™ today to upgrade your comfort.

WindowSkins are not yet available direct purchase by consumers. But we are building a network of Certified WindowSkin Installers and will notify you as soon as there is one in your area. Join our mailing list to stay informed as we bring WindowSkins to market near you.

Independent Validation

Taitem Engineering P.C. in Ithaca, NY has validated WexEnergy's Basic WindowSkin™ prototype performance. This validation was performed in Taitem's test facility for testing window insulation performance.

The validation study of a single pane window with the earlier prototype mounted on the Base Window found a 33% reduction in heat transfer rate compared to the same single pane window, alone. This result corresponds to 82% of the improvement expected by replacing the single pane window with a new air-filled double pane window. WexEnergy LLC anticipates improved test results when the current prototype is tested. 

These test results will be posted as soon as testing is completed. The validation study of a double pane window with WexEnergy's Basic WindowSkin™  found a 23% reduction in heat transfer rate. This corresponds to a 24% improvement in energy efficiency performance or the equivalent of a current Energy Star rated window for Southern US Climates.

Innovation Fund AwardS

WexEnergy LLC received a 2016 Innovation Fund Award from the Syracuse Center of Excellence in Environmental and Energy Systems (SyracuseCoE). Under this award contract, independent validation of WindowSkinTM performance was conducted by Taitem Engineering, P.C. in Ithaca, NY at a facility designed to test window performance. The study also  modelled energy savings for WindowSkin™ prototypes, including low-E prototypes (next generation), on an air-filled double pane window. This window type was chosen because it most closely mimics the energy performance of  double-pane windows that are at least 25 years old.

The energy modelling found an average decrease of  ~11.5% in Natural Gas usage (range of 35% to 9%) when WexEnergy's Basic WindowSkinTM is mounted on an air-fill double pane window.  An average decrease of 26% in Electric Energy usage (range of 40% - 25%) was found when the next-generation WindowskinTM is mounted on an air-filled double pane window.
