3M Prestige Exterior films for home windows

7 years ago

Anyone have any info/insight? Looks like these films go on the outside of the window which helps prevent the window itself heating up (since interior films would reflect heat from the film to in between the two glass layers of a double pane window). The PR70X shows a LSG of 1.6, with 63% visible light transmitted and a SHGC of .39.

What would the cons be? Durability, cleanability...?
