<strong class='bbc'>Wow guys, after checking out the town hall by edmunds.com out 580 posts tells me that no one there knows any true facts about window film it's just hearsay and crap. Huper Optic have made some claims that are alittle twisted to make them look better than they are! I see the best film made with only a 5 year warranty!!!!!!!!!!!!!!!!!!!!!! PLEASE. they don't publish what the heat rejection is for these films as it's not that great. Ultimate made by C.P Films e.g 50% rejects 38% of the heat @ 42% glare @ is only 5% reflective not 8% as per Huper Optic @ has a manufacturers lifetime warranty Nationwide with 300 dealers in the USA. try finding more than 3 dealers for Huper Optic. so don't get sucked in by twisted claims, there film rejects more heat only in certain nanometer wave lenghts. buyer beware!

Hi svtsean,
Could it be that the negative posts that you read is because of confusion between tinted films and solar films? Tinted film are coloured films that does nothing more than add colours to your windscreen. Along the way, these tinted film do cut out some heat, but that's secondary.
Solar film is made specifically to cut out heat, not colour your glass.
I'll be the first to admit that I was a sceptic once. In fact, I was so sceptical that this is what I did.
There are a few brands in Singapore, including Llumar, Huper and V-kool (with V-kool being around the longest and supposedly the best). I got llumar to install the "home" version on my apartment windows (the side that faces the afternoon sun). I chose Llumar because it was the cheapest. That set me back US$60 for 6 panes.
I was very impressed with the results. I tested the film by opening one side of the window and comparing the heat coming in against the side with the window shut. That made me a believer.
For my car, I installed the Huper which is supposed to be a better grade as far as infra red rejection goes (infra red is supposed to be the ones which causes most of the heat).
If you're wondering why I didn't stick with something which worked, that's because the authorities in Singapore require at least 70% visible light transmission through the front windscreens and windows (50% through the rear windows and windscreen). The tint on Llumar's film was stronger and complaince would have meant getting a lower grade than what was available on Huper.
But don't get the wrong idea. These are no miracle films. If you park your car under direct sunlight for hours, your car will be hot. It just slows down the heat build up, not eliminate it.
Below are two links to forums with members mostly in Singapore. If you do a search on words like v-kool and huper optiks, you can find some useful information. In fact, in the Seat forum, I'm currently trying to guage the effectiveness of the solar films by getting fellow Seat drivers to contribute fan speed readings. Will let you guys know once I get enough feedback.
