3M Prestige 70 Solar Window Film Performance Demonstration

3M Prestige 70 solar window film has a patented construction that has no metals in it thus it is not reflective, will not affect 5G and will not corrode. The demonstration also shows how the film reduces solar heat gain associated with warmer, summer months. The demonstration used a BTU meter along with infrared heat lamps to measure heat transmission (gain) reduction. This demonstration was conducted at the NGS Solutions Center in Atlanta GA. This product is an excellent product to improve building energy efficiency- sustainability without having to replace the windows. NGS is a leader in supporting building sustainability and resilience. NGS has multiple contracting vehicles and installs nationwide.

It's a perfect solution for modern homes with floor to ceiling sliding glass doors or modern homes in general since a large portion of the house is made out of glass. This will mitigate the heat.

I’m considering putting this on a particularly large non-opening architectural window. BUT the window has lots of thin wood panes. Can it be installed over the panes as well to help with water leaks or does it have to be cut to each individual glass pane?

so.. im wondering why we have not seen window film solar panels. as in window tint thats also energy capturing solar panels. it only makes sense that buildings windows should by all means be solar energy capturing panels. Glass abundant skyscraper should be solar power plants considering how much sun light they are exposed to. hell one could argue most of its energy requirement could come from its own windows and exterior surfaces.

This product seems promising. But I'm not convinced from this type of demonstration. I don't think the testing environment is measuring what it intends to be measuring. Seems like you'd need at least two glass cube rooms, one of which would be the experimental room, covered with a single type of film, and the other glass cube room would serve as the control, with no film. A sun-simulating light should then be shone for the same amount of time on each cube, then measure the heat.

Nanoceramic is very bad product cause they don’t say
Glass increase heat like 60• C
