Reflective mirrored window film on double glazing?

Is it possible to put reflective mirrored window film (self-adhesive) onto double glazed windows? I've heard that doing so will cause the double glazing to crack due to the way the window film reflects the heat being incompatible with double glazed windows.

If this isn't possible will "blackout" film also cause the same issue as "reflective mirrored" film?

I understand that putting window film onto single pane windows is fine though.

Personally I would use what's called a one way blind it let's light in but you can not see in from outside and I have them very good

I know that reflective film works on single pane windows such as shops. Usually shop window glass is laminated safety glass. My personal opinion is I've never heard of any film that's been applied to glass whether it be single or double glazed to cause it to break.
