With funding from the Energy Department, the National Renewable Energy Laboratory (NREL) is working to develop innovative insulating window film that preserves views while increasing occupants’ comfort and saving energy according to an article on Energy Department’s website.
This research effort creates a millimeter thick insulation film that results in clear insulation with values equivalent to R-20, which is equal to standard wall insulations. The new technology will boost the energy efficiency of current window retrofit technologies by as much as 80 percent and building and homeowners will not need to replace their windows to take advantage of the technology!
Considering the billions of square feet of installed windows in the U.S., the NREL research provides a ripe opportunity for saving energy, reducing costs and cutting carbon pollution. The result: This window film could reduce building energy use by as much as 33 percent, creating a simple payback for window retrofits of less than one year.
