Buydecorativefilm BDF S35 Window Film High Heat Rejection Reflective Silver 35 (Medium) - 36in X 24ft

Q: are the squeegy and knife included?

Yes. A small retractable razor blade knife and a small squeegee are included and work just fine. We used them to put the film on windows and glass cabinets and they worked great.

Q: What are the vt and shgc values?

I do not know what vt and shgc represent?

Q: What is the differents between bdf exs35 and bdf s35?

It looks like the BDF EXS35 is installed on the exterior side of the window and the BDF S35 is on the interior. I'm not sure how the BDF EXS35 would withstand the elements. You might want to consult with the manufacture before in stalling this on the outside. I would never do that.

Q: Could I put these on backwards with the mirror side facing the inside of my room to make big windows into big mirrors at nighttime?

There is an adhesive on one side only, but you can still get a mirror effect inside if the room is bright enough and the outside is dark enough. However, the mirror effect will not be as effective as the daytime. You should check out our Silver 5 and Silver 15 window films, which will create a better mirror effect (day and night), but allow less light in during the day. It would also help if you had bright lights indoors.
