Hi,
We have a Subaru Forester that has privacy glass on all the windows behind the driver and passenger window. Before picking the car up we paid to have the drivers and passengers side windows tinted and all the rear windows to have a UV reduction film put on.
For the life of me I can see where the film was installed on the rear windows. The front two windows have also been done so
well its almost impossible to tell that it’s a film and not part of the original glass.
Is there a way to
test the rear windows to see if the UV reduction film has been installed?

With film, if you wind any window down and look carefully at the top inside edge, you should be able to see the edge of the film where it was cut. Another
test is to take a pin and carefull (close to an edge) try to pierce the (any) film. It should be very obvious to you if there is a film present or not. If there's no other way you can decide then I suggest you call into a window tinting centre and get them to
check for you. Good luck with it.

Thanks, I am just suspicious that I have paid for something I didn't receive.

Try heating a pin with a match and then 'pricking' the window in an obscure place. If there is any film there I think you will smell the effect of the heated pin on the plastic. Also a good way of testing some jewellery such as turquoise to see if it has been 'stabilised' with epoxy etc.

I'm curious; why did you fit a UV reduction film? I was under the (perhaps mistaken?) impression that ordinary glass filtered out the vast majority of the UV anyway?

Glass filters most UV but not all.
Most window tint film will remove over 99% UV.

Gotta agree with Mike, wind the window down(never owned a push button thingy to do it) get sunburnt. Leave the window up (if the a/c is working) no sunburn.

Ordinary Glass has 0% UV and lets too much light in.
Privacy glasss is 0% UV, its just coloured glass.
This rubbuish, privacy glass, is the same that gets put on $30K cars right up to $150K Mercs.
That is to say that even buying a $150K merc, you still need to get the whole car UV tinted.
Makes matching the front and back hard. And because you have to UV tint the whole car anyway, why do the manufacturers even bother putting on this farcical rubbish?

remove all clothing and sit on the back ledge was my initial response,
but seriously, i've just got a pair of those specs whot change shade on their own.
they only respond to uv and not sunlight, you could maybe
test the window with a pair of these.

Use the pin. A pin will slide across the glass, but stick into the polyester film on the windows.
If you look at the black ceramic edge around the windows, you shoul be able to see an edge of the film as
well.

Dustin.
If you look at a blue coloured object in the light coming through the window it will look greyer if the glass is uv filtering. Eric.
