One of the best things that has ever happened for the window film business has been the increased credibility of our film solutions by the National Fenestration Ratings Council.
You have seen their stickers before on new windows.
Documented performance of the energy efficiency of a particular window compared to another manufacturer’s.
The window film industry has been provided a path toward receiving Energy Star status.
The logical first steps were to independently test and document a film’s performance of standard retrofit glass configurations.
The first company to complete the process was Eastman Chemical Performance Films with our Vista and LLumar brands.
They were followed by Southwall (Huper Optik and V-Kool) Later Madico, Solar Gard, Johnson and my alma mater 3M.
Leaving aside the minutia that might make your eyes glaze over (pun intended!) How does all this mumbo jumbo help the consumer?
The true measure of a window films efficiency is the solar heat gain eliminated by the window film.
So despite the baloney by 3M that their prestige film works better at an angle compared to other films, or their fable that they created a special test to prove this.
The truth is that there simply is no such criteria or factual basis behind their claim of uniqueness.
