Is this film safe on all types of glass? Do I have to worry about glass breakage on a low E pane?

This white film has a reflective gloss finish and a very low absorption rate so it should not cause any issues on the glass. Here is a link to the spec sheet showing it is safe for all glass types: https://www.decorativefilm.com/mm5/graphics/00000001/SXF-5050%20TotalLightBlock.pdf
