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.
