Hi Guys.Just need to clear up something here.I heard a myth that the old style of cars for example my 1970 Beetle,does not have a laminated(right word?) Windscreen this means that if a rock hits it,it will Shatter or crack much more than other windscreens would.My front windscreen is marked Sunzone,but all the others are marked Armourfloat.Does this tell me anything?If this is true ,i intend on taking it to a windscreen place and getting them to laminate it.if they can.

Any info would be greatly appreciated.

Is there any more markings on the glass, down low in one corner possibly, etched.

I would be very surprised if its possible to laminate an existing screen. Laminate meens 'to layer', so its done at the factory, a flexible membrane between two layers of glass. So if broken it still holds together. The non-laminated will shatter into thousands of tiny cubes.

You can do a test to see if its not laminated. Hit it really hard with a hammer, if it shatters into thousands of cubes ... it was the old style.
Do I need to add that I'm joking?

on all the original glass if its amourfloat it will


have a look at the armourfloat and there will be a dot above one of the letters

you can work out what year from that

dont know when they started doing it but in 68 itll be over the 8th letter, 69 9th, 70 10th and 71 is the back to the first and so on

Sunzone is zone toughened. It is toughened glass, being original style. It may have been replaced sometime in it's early life, but it was replaced with a toughened glass. You do not have to replace it unless it is sandblasted or unservicable in some way. You may wish to replace it with a new laminated glass anyway. You will find the new glass will give a clarity that you did not realise until the new glass is fitted.

Supply and fit a new laminated glass is about $180 from a reputable windscreen place. If your rubber seal is old, it may be hard and will need to be replaced also to do the job properly. A new good quality seal will cost about $50.

yeah true,Do you think those mesh windscreen protectors(at top) help with rocks? i never thought they did because its only the top couple inches that the windscreen thingo protects.I think they are mainly for shade on your dash.

never heard of sunzone...

but usually, a laminated glass will have that printed on it..

I replaced mine when doing the resto...

I had My share of windscreens shattering all over My face....

then the blood trickled from My forehead

true....

I still have My original one too...

and Joel,
My Son has a few old beetles still with original windscreens
lol

He doesn't drive any of those... lol

the shatter type of windscreens-

they are made of toughened glass and the later ones had a zone in front of the driver that was heat treated so it didn't shatter as much & You could still see where you were going if it shattered at low speed...

high speed.. didn't matter... all over you....

guess they forgot about that part on my celica

it was late at night and raining but as i came into a corner i passed another car and my windscreen completely shattered
i thought they must have thrown a rock but looking around the next morning i found one very bent up wheel beauty ring.

when it shattered i couldnt see a thing, i just remembered i was in a corner and hit the ancors
came off the road abit but luckily there was nothing to hit

had to knock a hole in it with my jack so i could see to get home

There was a simple test for toughened screens (they are not allowed at the race track, by the way) - look at it though a pair of Polaroid sun-glasses. If you see a pattern of 'blotches' it's toughened. You can also make out the 'safety zone'. Not sure if Polaroids are still around - ask your grand-parents, perhaps!

Toughened glass screens are harder to break and harder to chip, but when they do go, they break into approx 3mm chunks, except for the toughened area in front of the screen with is more like 5-6mm to allow some extra vision.

Laminated screens chip/crack more easily but allow you to continue your journey and can in the case of minor chips can sometimes be repaired.

I've had a toughened one let got at 100km/h on the hume highway approaching Goulburn. The area in front of the drivers seat was still okay to see through to pull off the road. I didn't get any cuts.

I've also had multiple laminated ones break.

Personally I would not worry about the toughened screen. Just carry a roll of tough clear plastic in the car and some electrical tape so you can rig up a temporary screen to get you home, if it ever happens.

I have broken several toughened screens over the years - mostly I have had them stay intact and been able to see through the clearer chunks in front of the driver.
The first one I broke was as a young bloke and it was on a wet day. The wipers still worked on it OK, and I drove straight to the VW dealer (still the place to go back then - late 70s) to get it fixed before I got any rain in. I pulled up at the dealership OK, got out, then closed the door. Unfortunately, this compress of air in the car with all the windows up (to keep out the rain) blew the windscreen out over the bonnet in a sheet of little bits. lol.
If you do break a toughened windscreen and want to keep it intact, dont close the door with all the windows up.

Will shade tinting have the same affect?
Thanks for all your help

They must be Polaroid sunnys. To toughen the glass, the blow cold air onto the hot glass from jets in a grid pattern. The pattern varies from maker to maker, but ,with the help of the Polaroids, you can see rows of circles in a grid (except for the 'safety zone' ). A laminated screen should be clear, with no pattern. Hope that's - excuse the pun - clear.

Yeha they were polaroid sunny's(i think) all i could see was like a small colourfull oil mark,like when oil is left on the road.I think that might be from when i washed it.i coudlnt see rows of circles.but i will have another look.

more random and useless info... The small colored dots you see on car glass when looking through polarized lenses are from the cooling jets when the glass is made

like my grandma used to say " it didn't break 30 years ago, why would it break now? " hahaha
no about 10 years ago on my way to school in dad's 504 peugeot ute. sitting at the traffic light.
it was toughened glass
it just completely shattered by itself
there were a lot of small 3-5mm pieces everywhere.

I still have Armourfloat windscreen

Just today I had to pull apart a Melbourne hail damage 1962 Beetle for repairs. The front screen was Armourfloat toughened still. The screen came out no problems. The owner wants a new laminated one fitted at his cost for the glass when reassembled. He is in a lucky position where the labour part is taken care of by the insurance. The repairs to this Beetle will be metal finished as per my usual standard of panel restoration repairs.

If you guys want a bit more info on:

Laminated glass check out, http://www.azom.com/Details.asp?ArticleID=88

Toughened glass http://www.azom.com/Details.asp?ArticleID=87

Sorry shameless plug for the site I run, but hopefully this explains it all a bit.

Bottom line is, they will both shatter if hit hard enough.

Toughened glass will be more resistant to shattering due to the fact that the heat treatment induces compressive stresses in the glass, but when it goes, it goes.

Laminated glass will crack more easily, but the fact that it has a plastic (PBT) layer sandwiched between 2 layers of glass means that the windscreen will be more likely to stay in place even if badly cracked.
