Guest WillTint4$ Posted July 24, 2007 Report Share Posted July 24, 2007 Did a small flat job last week. Used a new film (its a silver 50). The exposure is due west, clear IG units. The customer has a very large glass coffee table between the sofa and the filmed windows. The reflection of the filmed windows on the glass table is one big rainbow of color. The reflection before film... no rainbow . Looking at the film from inside is fine. While sitting on the sofa watching the sun set you cant miss this swirl of color on the table. What causes this?????????? I think it looks really bad. Link to comment Share on other sites More sharing options...
Guest FilmBlazer Posted July 24, 2007 Report Share Posted July 24, 2007 I'm guessing polarization Link to comment Share on other sites More sharing options...

Guest haroldshouseoftint Posted July 24, 2007 Report Share Posted July 24, 2007 OK, my hypothisis (sc) of this situation, is that the film is removing the harmful UV rays, and refracting the light, thus in doing so, it is creating a "rainbow" effect on the coffee table when the light hits it at certain angles I almost sound smart, where's Vclimber to correct me Link to comment Share on other sites More sharing options...
Guest Marco Posted July 24, 2007 Report Share Posted July 24, 2007 I "almost" sound smart, I was thinking the same thing I have no idea what causes stuff like this Link to comment Share on other sites More sharing options...

Guest FilmBlazer Posted July 24, 2007 Report Share Posted July 24, 2007 I believe V is referring to the coffee table. I have seen this before... If you look at filmed windows with polarized sun glasses on, you will see a rainbow appearance with most dyed and metalized films. I always thought it was from viewing polarized glass through a polarized lens.... Polarization of a polarization if you will. Interior light will also cause this rainbow effect with certain metalized films like MM said, but it doesn't sound like a lighting issue here. Fluorescent lighting will cause the spectrum to appear on the filmed glass, not so much the coffee table. I'm with V, its got something to do with the glass on the coffee table. Do you think it is the PVB (Polyvinyl butyral) between the layers of glass in the coffee table? PVB is the resin between the layers of glass in laminated glass that holds it together during impact. I'm thinking the only way to fix it is to change the glass on the coffee table or go without film Link to comment Share on other sites More sharing options...

Dont get me wrong, im just curious. I always thought they were either just tempered or regular glass. I've broken a few in my day and most were just reg. glass.
