Hi, I’ve noticed with some new Low-E3 (Cardinal 366) windows that have  plastic wrap / protective film intact on inside and outside surfaces that the interior side of the windows in full sun gets pretty warm, measured about 98 degrees or so. Temp drops when the protective film is removed.

Wondering what the science behind this is, does the exterior or interior plastic interfere with the emissivity/reflectivity of the Low-E3 coating?

If we add impact or fragment retention film later, would this also affect the Low-E3 coating? If so which would be the better side to apply the impact film, outside or inside surface?

PS we do not have the i89/room-side coating.
