Laminated windscreen?

    I did the same, I fetched the new screen from a guy somewhere near Warwick Castle if I remember correctly.

    This was a tiny part of my thinking when I eventually got around to raising mine a little. Hopefully most cars I could slide over moreso than tickle them with my toesies.

    On YouTube there is a crash test vid with a type 25 and a Volvo 244. The Volvo driver would be dead. As you say, your van should ride up over the car. But cars are bigger these days, so…

    Once seat belts reduced peoples heads going through toughened screens, the greater strength of a laminated screen helps stop the front of the vehicle from collapsing as much.

    Modern cars have glued on screens to create structural panels that happen to be see-through.

    Best I get on with putting on that pedal pan and maybe some ribs on it as well so it can be a belly pan / skid pan / up and over thingy and flying carpet too.

    Ozziedog,,,,,,,, hopefully never to be tested :)

    I will reiterate so no confusion- whatever glass you have if you have a head on collision or go up the back of someone at speed you are not going to fare well in a t2 bus - however you may not get showered with glass but again you will be very unlikely to be giving any consideration to that in this situation.
    Laminated glass great if a rock hits the windscreen or some little punk chucks a brick off a bridge etc

    So advice is
    Drive carefully
    Make sure brakes work well and van road worthy ( yep I still do an mot each year )

    Me too and apart from the emissions not being too applicable, the older these get, the more they need a real good going over periodically. On one of the Facebook forums recently over the last couple of days, a lady parked her T2 in a car park on a steep slope and the handbrake wouldn’t hold, so she screamed at her hubby and a passer by to hold the van while she selected reverse to save rolling in to the parked car in front. She asked, is this how they are? I replied suggesting some regular maintenance and an mot as a hand brake doesent just fail apart from a broken cable and that was when she got all shirty and told me that her fab garage checks everything every six months and mots it every year. Wonder where she takes it?

    Ozziedog,,,,,,,,,,, or maybe she don’t pull hard enough:shock:

  9. Hello everyone,
    Windshield made of laminated glass (glass/plastic film/glass) was only available for an additional charge M-Code 089.
    In the event of damage, the plastic film holds everything together without dangerously large shards.

    The standard was glass tempered at 600 degrees,
    which, if damaged, would shatter into harmlessly small pieces, instead of large shards that would cause nasty cuts.

    New replace windshields have "II" for laminated glass over the ECE certification mark as here over the (E2).
    And you have a clear view again without scratches - glare-free at night.

    But anyway and to the frequent travelers and globetrotters:
    in the past, replacement windshields made of thick film were common as an emergency aid.
    This means you can get home or to the nearest workshop without flies between your teeth or icicles under your nose. ;)
    (I always have one with me - bought old ones cheaply from the classifieds)

    And if not for you, it could help your friend as in this case: bay window transformed to a (wooden) split window: ;)

    I'm confused (admittedly a common occurrence) but I hope you can help. My M codes read as follows on my American import:-

    "M 246: Windscreen free from import duty for USA (with M89 only)"

    But the M89 code is not shown separately in my M code. Obviously, this may not be the original windscreen, but I think it is and and my limited research suggests all US imports after '66 had laminated glass. The picture below is of my actual windscreen and doing a bit of research it seems AS1 is laminated, but I've been told it is not laminated so I'm confused IMG_20231002_134856825.jpg ...what do I have, I think I have laminated but just checking?

    The easy way to find out is to look at it through a polarized lens.. the toughened windscreen will show colour fringes around its built in stress patterns.
    Sometimes light from a cloudless sky is polarized enough that if you look at the correct angle at the screen, you can see the patterns.


    If you break that one, it will be replaced with a laminated screen unless you buy a secondhand original.

    One small problem..I don't own a single polarized lens...but good idea Mike.

    Not even sunglasses? Most of those are polarised

    This.
    Both of my aircooleds still have toughened glass and with a pair of sunglasses on I can see quite clear vertical banding on the glass (even without sunglasses on a sunny day).

    Nop, not even.sunglasses...the reason is that as a paragliding pilot, polorising lenses at various angles can block out seeing electrical cables that are not healthy to hit!

    A monochrome LCD has polarizers on it so you might be able to strip apart an old LCD..
    Or wait for the sunshine and polarized sky. Also I am pretty sure the UK glass always said Toughened on it.

    I seem to remember that old laminated glass with damp edges may be milky round the edge.

    Camera polarising filter perhaps? :)

    Just throw a brick at it @Chrisd, you'll easily be able to tell
     
  19. At least in a late bay, you'll fare far better than you would in any other earlier T2 due to the vastly improved lower front crash structure added to the later buses. (Assuming it's not riddled with tinworm!)

    As for glass, although more messy when it does break, it's far harder to break a toughened screen in the first place due to stone impact or bird strikes, than it is to crack a laminated one.
     
  20. I read different descriptions - and have no access to the standard papers ANSI-Z26.1 for AS (American Standard) codes.
    My current knowledge level:

    AS1: windshields, at least 70% light transmission, laminated glass :thumbsup:
    AS2: side windows for visibility to the exterior mirrors or rear windows, at least 70% light transmission
    AS3: other glasses in the vehicle, can have less than 70% light transmission

    Only the renewed clear glass windshield is AS1 at mine. My bay window with M-568 green tinted thermal insulation glass around with AS2 - others with clear glas also with AS2 side windows - some sources wrote AS2 is only for tinted glass, thats wrong.

    Your glass manufacturer SIGLA (Sicherheitsglas GmbH = safety glass, founded 1938, Germany) registered also as DOT25 is today Flachglas Wernberg and for some years part of the British Pilkington Group.
    Found also old SIGMA glass for Mercedes and other VW in the local classifieds...

    The wavy line with "D-"code was for the German Federal Motor Transport Authority (KBA).

    The M90 is unknown... but not a VW M-Code!
    Also unknown the E under the SIGMA logo.
