Let's talk windscreen/windshield Options

[Montreal914]

I am currently looking into getting a windscreen (as the UK or parts catalogs calls it) but I am only interested in one that would have the original shape (rounded top).

I saw a few restored 914-6 on display at Rennsport VII with the OE windscreen shape and they were Pilkington, not Sigla. I wasn't able to confirm if Pilkington is the new supplier of Porsche 914 windscreen replacement part, but I have a strong feeling it is.

These OEM windscreens are available in clear or tinted per these two part numbers.

Clear: 914-541-101-10
Tinted: 914-541-102-10

By tinted, I am not sure if they mean with a dark shaded band at the top or overall tint like the side glass (Delodur-1 and Delodur-F, -1 clear and -F tinted).

If someone has this information, please comment. (IMG:style_emoticons/default/smilie_pokal.gif)

My car has the Delodur-F (tinted) side windows and I would like to get the correct windscreen for it. That being said, I am not interested in having any dark shaded green band at the top, I would prefer clear, hence the question above.



For those who aren't familiar with what I am referring to as the shape, I found these two pictures trying to show it. The orange car (Porsche's 914-8) obviously has the genuine windscreen while the red car has a generic replacement. You can see how the top part of the windscreen is "bubbled up" creating a nice flowing live vs a sharp transition.

I know what you're talking about, and noticed this phenomenon with the windshield in my 1973 914 in the early 1990s. Fwiw, I actually preferred the looks of the replacement windshield, which lost the "bubble" vibe of the first one, and still do.

But I'd love to know more about this detail.

As for tint, my current windshield ordered through a Porsche dealer is all clear—but I think I preferred the way the tinted upper section in my last one was super subtle yet hid the gangly visor hardware in my car, old Automotion stuff that allows you to swivel the visors to the side windows to block a hard sun.

@horizontally-opposed : Are your side windows tinted (Delodur-F) or clear (Delodur-1). Is the windshield matching your clear or tinted windows? Just wondering if by "tinted" Porsche is referring to the upper colored band, or the overall light green shade tint like the -F side glass.

Here are the two cars from Rennsport with Pilkington windshield. All same number but probably a different production year, notice the variance in inscriptions.








EDIT: I think I have found my answer. Looks like the top colored band is too modern and was never offered on our cars. The tinted is for the whole glass per images taken from Sierra Madre Collection Website, both Genuine Porsche.

i can decode those screens montreal914.
they are both identical.
they are clear screens (laminated safety glass).
these days clear is defined as more than 70% light transmittance.
this is pretty much where clear screens are in the modern era.
at 70%. slightly darker than a clear screen in the late 60s early 70s.
the indicator of that is the two vertical marks II above or next to the E! in the circle.
E1 in the circle means it meets german standards and is a screen sourced from germany.

if it was a tinted screen (ie less than 70% transparency it would have a V above or next to the E in a circle.

it really depends on the country whether you can have less than 70% trans.
i know in australia you can't. any darker tinting is restricted to a band above the central zone at the top of the window. most modern screens if you look real close have a line and and an arrow marking on either side down about 6 inches or so from the top.
above that line a darker tint can be applied.

both those screens are identical.
only thing different about them is when they were made.
that is indicated by the dots and the number which is the last line of the markings.
the number of dots tell you which month. the number indicates the year.
for instance the bottom one of those two was made in feb 2007.

i think what there is to understand these days and this relates to your question. tinted screen or not is that pretty much all windscreens are produced with glass at around the 70% transmission point. this is for reasons of health. ie skin cancer. that the limit in most countries by regulations so they take it to there. and thats called a clear screen.
and a tinted screen gets the darker band at top above the line and arrow markings.
and its an applied coating.

back in the 60s and 70s i think it went like this.
a tinted screen was a darker glass that went down to the 70% transmission threshold.
and a clear screen was much clearer with higher light transmission.
in the current age i don't think you can easily get a screen as clear as original ones used to be.

but if your car is meant to have a tinted screen to match tinted side glass then the current pilkington screen as you have photographed from two cars would i believe be the closest thing to what was in fact the tinted screen back in the day.
