Plate Glass or Not?
Hi all. I just bought a '28 Briggs Fordor Leatherback. It was restored 30 years ago by the person who owned it before the person I bought it from. My question is, how can I tell if the side glass is plate glass, or if it's been upgraded with tempered glass? The top of the windows are painted black. The paint is missing in some spots. The glass is really clean with only one minor scratch from something rubbing while rolling up or down. It seems like 89 year old glass would be worse...
One "smart" guy from my club said he knows how to tell. But then I'd have to replace it. haha. Any advice? Thx. Marty |

Re: Plate Glass or Not?
Be careful of your terminology.
Tempered glass is single sheet glass which has been "stress relieved" after the manufacturing process to make the glass more resistant to impact - and if broken tends to fall in single large pieces. Safety Glass (laminated glass) is the triple layer glass used in all modern automobiles and is the glass Ford adopted for the front windshield after a near fatal accident involving one of his design engineers. Original safety glass has the edge "bonded" in some sort of black. Modern safety glass will show the three distinct layers on a ground edge.

Re: Plate Glass or Not?
If you have plate glass and not safety glass I would change it before you do too much driving. Plate glass is very dangerous in an accident.

Re: Plate Glass or Not?
Here is the 'correct' info on tempered glass vs laminated glass... from the Ford Garage. Thanks once again Vince.
http://www.fordgarage.com/pages/craiglewisglass.htm Most "local" glass shops will sell you laminated glass because they can not cut tempered glass. They have to special order it to size. Laminated glass should not be used in your side glass. Check with Bert's, they sell tempered side glass for your Fordor. I just replaced the drivers window in my Town Sedan because it was cracked. And yes, the one I replaced was laminated. Last edited by Y-Blockhead; 04-21-2017 at 06:15 PM. |

Re: Plate Glass or Not?-YOUR WINDSHIELD MAY be PLATE GLASS !!!

As I remember the glass company referred to it as "safety plate". The edges are clear glass and you can see the two glass pieces and the plastic sheet in the middle. Note all the other windows were plate glass I was told in 1976 that Ford put safety glass ONLY in the windshield which agrees with what I found in 1962. In 1966 I hit the rear of a 56 Plymouth at 45 MPH. The seat belt that I installed in 1962 kept me from hitting the windshield which was really a good thing considering what I found in 1976. In 1976 the windshield glass started to rattle inside the frame. When I removed the glass windshield I found that it also was plate glass. Many dangerous things happened to save money in hard times. So do not assume that because Ford put safety glass in the windshields that yours is in fact safety glass! Last edited by Benson; 04-21-2017 at 11:31 PM. Reason: correction: install ed |

Re: Plate Glass or Not?
A quick check online seems to show only laminated glass. Even from supposedly high capability producers such as http://www.classicflatglass.com/Ford_Auto_Glass.aspx?

Re: Plate Glass or Not?
I don't have a clue about what you guys are saying except windshields need to be safety glass (3 layers) and side glass makes no difference.
I am replacing the front window in my A. It was and will be safety glass. The side windows will and are whatever they are. Your modern only has 3 layer glass (safety glass) in the front window so why get you shorts in a bunch . |

Plate glass is just as dangerious in the side windows if you happen to go though the window like if someone hits the side of your car. I have seen it several times with accidents involving plate glass ... it is NOT pretty. Cars now have tempered glass in side windows which breaks into thousands of very small pieces that do not cut your head off when you strike the window. The new cars that I bought in the 1960s had safety GLASS in windshield and tempered glass in side and rear windows. Last edited by Benson; 04-21-2017 at 07:49 PM. |

Re: Plate Glass or Not?
I can't tell you if your glass is plate glass or tempered glass, but if you think it might be safety plate (3 layers: glass, plastic, glass) just hold a pen or pencil against the glass and look at the glass at an angle. If it is plate glass you will see one reflection. If it is safety plate you will see two reflections.

I even searched Berts since they are my go-to for those hard to find parts - but I think I was searching a wrong web-page - Berts has more than one - and came up blank on searching "window." I'm still looking in the barn for my 1990s era side locally produced side windows to check them for safety or tempered. I should build myself a smaller barn next time. NOT Joe K

Re: Plate Glass or Not?
I find it interesting how the words "death trap" have come to condemn laminated side glass in some circles.
Yes, it is tough to kick your way through laminated glass, but tempered that does not shatter is no better from a safety standpoint. You cannot kick through it in an emergency. Ever see all those little pointed escape hammers sold so you can get out in an accident? I don't dare suggest the fact that tempered is way cheaper to make than laminated had anything to do with automakers making the side window material switch in the '60's. Nor styling trends... When you travel by bus or train the side windows are laminated, not tempered. Apparently the rules are different. If my A were ever to roll over I'd rather have broken laminated holding my head inside during the roll than shattered tempered letting my head get the view from outside. Of course, all this is probably a moot point, as everyone knows a Model A door flies open easier than a refrigerator door on Saturday night. Got seatbelts? I'll take laminated for side windows if I ever again replace glass. |

Re: Plate Glass or Not?
I've never seen any real reason,in real life,to pay the big money for tempered glass instead of laminated for the side windows in an A.Laminated glass does not slow the rescue guys down a bit.I watched some of them demonstrating and practicing in a junkyard,8 seconds to take out a side window with nobody behind it and about 20 seconds if somebody is right up against it.My Macks,Brockway,and older International trucks all had laminated in the sidelights.My later IH and GMC Astro had tempered.
