Sooner or later someone will be seriously harmed by this practice so think first before you do something you may regret later.

I agree proper tinting of the screen is insanely stupid (IMO)
The only reason why I'd want the clear film is because its perfectly clear, thus not presenting a safety hazard at all, and the obvious plus point of reducing heat in the car.
I'm pretty sure the rules and regs were written to stop dark film being applied.
They are also out of date and not up to speed with new tech.
If the film is optically clear and can be proved so, I don't see any possible reason why any authority would object to it.
How do you get products ADR approved ?
Surely this is a product most of us would want ?

Just to keep the thread on topic.
This IS NOT about a dark film "tint". It has no darkness to it. It's CLEAR.
I'll make some calls tomorrow and get some proper answers.
For people to accept this is "illegal" and not question "Why" ? seems silly to me.

Does that also include inside the car, where most films are applied?

yep. regs dont state whether the film is inside or out. its the reduced visibilty thing they are regulating and that is pretty much the same if the film is aplied to the inside or outside of the glass.

infra red energy is the wavelength of light which creates the most heat when it tries to penetrate a dence/solid object. (ie; on a sunny day the roof of your car will be very hot, but hold your hand a metre above the roof and it will be much cooler, space in between will get hotter as you get closer to the roof because of radiated heat coming back off the roof).

Wikipedia
[edit] Heat
Main article: Thermal radiation
Infrared radiation is popularly known as "heat" or sometimes "heat radiation", since many people attribute all radiant heating to infrared light and/or to all infrared radiation to being a result of heating. This is a widespread misconception, since light and electromagnetic waves of any frequency will heat surfaces that absorb them. Infrared light from the Sun only accounts for 49%[8] of the heating of the Earth

if this film stops 97% of 49% of the heat coming into your car , its still going to help a lot.

UV or Ultraviolet light is at a shorter wave length and comes in UVA, UVB, and UVC bands. majority of UVB and UVC is stopped by the atmosphere. UVA and UVB are the most damaging. UV light does not create heat. that is why you can still get bad sunburn on a cold winters day.

wikipedia
The discovery of UV radiation was intimately associated with the observation that silver salts darken when exposed to sunlight. In 1801 the German physicist Johann Wilhelm Ritter made the hallmark observation that invisible rays just beyond the violet end of the visible spectrum were especially effective at darkening silver chloride-soaked paper. He called them "de-oxidizing rays" to emphasize their chemical reactivity and to distinguish them from "heat rays" at the other end of the visible spectrum. The simpler term "chemical rays" was adopted shortly thereafter, and it remained popular throughout the 19th century. The terms chemical and heat rays were eventually dropped in favor of ultraviolet and infrared radiation, respectively.[

i believe that the plastic film used in between the 2 layers of glass in laminated windscreens will stop most of the UV.

Can anyone see any reason why we can't apply a clear film to our screens ?

Read the specs on this 3M film

http://multimedia.mmm.com/mws/mediaw...zz&K2rjvZZZZ8-

Yes I realize that the product is for home/office applications, but I can't see any reason why it'd be a problem applying it to your screen.

After all no one would know

Are you trying to stop UV? As I'm sure you realise this film won't help with heat.

Only thought I have is your wipers might scratch it?

Did you read the PDF ?

This seems a great idea to me, wonder why it's not been done. As for the Renault etc purple tinge that's NOT tint it's a coating on the windscreen for the auto rain sensing wipers.

YOOT · 19-02-2009, 04:41 PM

Is it possible to apply tint to a curved surface? Won't it bubble when you follow the bend?

the rear and side windows on your car are curved arent they?

The dark automotive tint that is applied to windows, is able to be moulded when heated. When they tint you rear screen they place the film on the outside and cut it to size and basic shape then shrink it where needed, to fit inside the car.

graham_h · 23-01-2011, 08:24 AM

I'm going to revisit this idea and get it done.
I'll post results when I get them

Ben73 · 23-01-2011, 08:47 AM

Get one of those stupid sun protector things and put it on your window when parked. That will help get your wheel cooler

distortion · 23-01-2011, 08:57 AM

I know of and have used this film before... you will find it difficult to conform as it is not designed to do so. In fact, you pretty much have no chance of getting it on flat with no creases or bubbles... films tend to bend one way better than others (if at all) and the inside of a falcon's windscreen makes it a very difficult challenge even with a conformable film.

Sorry to be so negative! It is a fantastic idea, and there is a market for it!

I do remember one of the tint companies working on something like this a while back, never saw it getting to market though!

XRtowcar · 23-01-2011, 11:57 AM

This mob do a special process to reduce interior temps and UV.
http://www.protector.com.au/Windscreens-Windows.aspx
Oh and the Euro cars have an Athermic metal coating manufactured into the windscreen.
Cant seem to get them for a Falcodore.

Who says tinting is illegal?

ThaFlash · 23-01-2011, 12:06 PM

would of thought it would be wiser to put it on the outside like for freeway driving or similar, then peel it off like the V8 Supercars.....

zdcol71 · 23-01-2011, 12:16 PM

"Queensland Transport regulations allow the use of tinting film on side and rear windows of motor vehicles provided at least 35 percent of light still makes its way through the tinted glass.

For windows that already have a tint in the glass, the combination of the tint in the glass and the tinting film must still allow at least 35 percent light transmittance.

Tinted windows that allow less than 35 percent light transmittance are illegal.

Windscreens can be manufactured from tinted glass however they cannot be tinted using film. The exception is a band across the top of the windscreen no lower than a line drawn horizontally across the windscreen at the uppermost points of the vehicles original wiper blade travel, or no more than 10 percent of the windscreens area, whichever is the lesser.

Tint films must not have a reflectance of more than 10 percent.

For the purposes of vehicle roadworthiness, tint films must comply with the requirements outlined above and be free of bubbles and scratches that would significantly affect the drivers vision"

Not sure of other states but this is a summary of QLD legislation on the issue.
Would be surprised if other states didn't have similar.
(very old thread by the way, I'm sure this has been addressed elsewhere, though I understand the OP is in regards to a specific product)

They do read; bottom of page 2 of that NSW link given by AWD Chaser which also implies medical grade clear film is allowed.

Obviously tinted front glass was/is OK in the US. I have been wondering how I would go if I imported and fitted this to my LC Lancer (the Oz equivalent of the Plymouth arrow):

Ben73 · 23-01-2011, 05:59 PM

The rear and back passangers windows on my American car is darker then 35%.
More like 20-15%.... But it was like that from the factory last year, sooo I guess it's legal. It has no tint film, it's just dark windows.

HLC · 23-01-2011, 07:54 PM

get a sunshade/steering wheel cover? lol

After work on a hot day put your hand on the screen 10 minutes down the road and it will still be HOT!!!

I'm fairly sure Renault has a new windscreen that blocks out UV, however that's not going to stop the interior getting hot.

Bad Bird · 24-01-2011, 01:22 PM

Ummm, glass is only partially transparent to UV light, and is actually opaque to the lower wavelengths. They don't need to add anything.

It's infrared - the longer wavelengths - that mostly contribute to the heating of the car.

I was also thinking - for all the arguing that this thread has created... a simple visit to Autobarn/supercheap and the purchase of a dashmat, and a steeringwheel cover could have sorted this problem...

Even a beachtowel in the car could sort it short term...

I'm confused...

Unless I misread, legalities aside, a couple of posts indicate it is possible to reduce the heat generated inside the car. Definitely my preference.
