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

Windows are a major source of heat loss in a building. 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 rental unit 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 rental unit comfortable and consistent. And the constant drafts are really unpleasant as well.

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

Simple to install, this lightweight, invisible custom-fit window insulation system looks great, works great and  can be removed without any damage to your rental unit when you move out.

Just press the WindowSkin™ against your existing window to add an extra pane 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, because of the patented design, you won’t even notice anything on your window!

Keep your existing windows and window treatments – all you need to do is upgrade with WindowSkin™ and you’ll upgrade your comfort and your savings.

Tell your landlord or property management company about WindowSkins and ask them to contact us to see if WindowSkins are a good fit for your property.

WindowSkins are not yet available direct to 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 the right) 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.
