Harnessing Physics to Maximize SAVINGS AND Comfort

WindowSkin™ is a completely transparent custom-fit window insulation system that easily mounts onto existing windows, upgrading energy efficiency and indoor comfort. The result is an easy and affordable way to make single-pane windows work like more efficient double-pane windows, or to make your existing double-pane windows work like triple-pane options.

The science behind WindowSkin is well known, yet our implementation is both elegant and unique. When the WindowSkin is attached, a volume of air is trapped between your existing window and the panel. Like the gap between panes in a double-pane window (or the pockets of air in a down comforter), it is this layer of enclosed air – and its thickness in particular – that creates an insular barrier and improves the efficiency of the window.

WindowSkin is designed specifically to optimize the thickness of this enclosed layer of air, maximizing its thermal insulation properties. Plus, each super-lightweight WindowSkin is custom-manufactured to fit your window exactly, with a patented design that minimizes the possibility of air leakage, so you get to enjoy the benefits of an ideal thermal barrier, each and every time.

We guarantee the custom fit of your WindowSkin when you use WindoWare™, our highly accurate, patented software measuring tool which was developed by our sister company, WexEnergy Innovations LLC.

INDEPENDENT VALIDATION OF the Technology has been shown on single-pane and double-pane windows.

There’s never been an easier, more cost-effective option to quickly and efficiently upgrade all the windows in your home or building. WexEnergy’s WindowSkin delivers greater comfort and savings, by design.

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  an earlier prototype mountedon 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 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.
