Poor seal fit after windscreen replacement - Page 1 - Boxster/Cayman - PistonHeads UK

I had the screen replaced in my 987 CS last week after a stone put a large crack in it, but am dissatisfied with the fit of the seal where the screen joins the roof. They are coming back on Friday to remove it and attempt a better fit, but I was wondering if anyone here could throw some light on why this should have happened.

screen looks like it need to sit in another 3mm to me.

Yes when I complained to them they sent out a different fitter who suggested that the new screen may have an incorrect curvature to it.

Should'a gone to Paul at Glasstec! Out of interest Trev, who fitted it? I appreciate you may not have had the choice of fitter depending on your insurance... I'm sure Glassman can shed some light on your issue, he's on here - just pm him.

Is it an OEM screen or an aftermarket?

my insurance only fit oem In the 1st 3 years life of the car after that its a pattern part, I ended up paying my OPC for a screen my self in the end to keep it all Porsche.

Out of choice I would have gone to Glasstec, but my ins co would only contribute £150 if I used anyone other than their recommended company. And since an OE screen is circa £600, I didn't consider the extra to be worth it on an eight year old car. I'd rather not say who fitted it at the moment just in case I need to take it further.

Understood Trev, one of those things. Maybe try Manning next time your insurance is up for renewal - they don't take the peewee and have a Porsche specifc policy underwritten by Amlin. Open choice of glass replacement, £100 excess, along with track cover etc etc

Had exact same issue. When the 2nd installer arrived he said the replacement screen seal was no better and requested a genuine screen be ordered. When that was fitted my problem was solved. Even though the first and second screens were branded by same company that made the OEM screen, the seal, tinting and antenna Design was not the same as the genuine part.

There are other factors, but it would be easy to assume without knowing all the facts (which usually become apparent once you remove the screen have have a nosey). The best available part - especially in this type of Porsche windscreen is without question, OE original Porsche branded. I am yet to see a decent aftermarket version although if I were ti place one at the top of the pile in terms of quality, Saint Gobain (Sekurit) does stand out somewhat. This is the type of windscreen that if it doesn't look right within a couple of minutes of putting it in place, it never will no matter what the fitter does.

I was under the impression that the ST Gobain (Sekurit ) was an original Porsche fitted screen .It is on my 987 Spyder and my previous 987 screen had to be replaced and the window company Auto Windscreens fitted that brand after I insisted on original screen as the car was less than 3 years old .It did not cost me any more that the £75 excess and was done in my own garage took around 3 hrs and no issues .

The screen they have fitted is a Pilkington.

I've read a fair few threads of Cayman owners having issues with windscreen replacement. I made a point of requesting an oem screen on my gen 1 car and it took whoever did it two attempts. The first time it went in I didn't notice any issue until I heard wind buffeting on the motorway that wasn't there before and when I looked at the lower edge of the screen there was a big gap to the black plastic seal that cases in the wipers.

They - like other automotive glass manufacturers - produce a premium glass for the (car) manufacturer (and their after-sales parts network). They also manufacture 'another' version of the screen which may not be as good as the OE. In fact, there are usually differences in quality such as the quality of the mirror or trim hardware not being as good. The two are rarely made in the same factory (or even country!)

Can confirm as far as Saint-Gobain Sekurit are concerned, i was offered a SG Sekurit branded screen by National on first diagnosis, and was told this screen would be "exactly the same" as the Porsche one, minus the 'P' insignia above the logo in the bottom right hand corner. Another example of Porsche tax it seemed initially. However this screen I was told would come from South Africa apparently....and SG is a French company, so this set the alarm bells ringing a bit louder. Further research on here and a call with Glassman confirmed that there is a definite difference between the OEM and aftermarket versions produced by SG Sekurit, and I went with OEM as my insurer (Manning) covers this. Should be more transparent of course, but in this case aftermarket appears to carry a greater risk of poor fitment/quality. Pilkington are allegedly a few more rungs further down the quality ladder...If you're not offered a choice, doesn't make it easy!

anonymous said: [redacted] Good point. Removing a windscreen intact, and without damage it or the car requires a bit of extra skill, and will. As with a normal application, the consumer sees a new windscreen sitting where a windscreen should; what you do not see is any sin or damage which will the new glass will be hiding. Any corrosion issues (or water ingress/wind noise resulting from poor prep) will not manifest itself until some time later (or after the new owner inherits them with the purchase of the car).

Just to update this thread. Autoglass sent two fitters out to me today with another screen and I'm pleased to say that the fit is now as it should be.
