Simple. The hat weighs 83.5 lbs. based on the fact that it's a 10-gallon hat with a gallon of water weighing 8.35 lbs.This guy might not care about the extra weight of the glass roof but he WOULD appreciate the headroom.

Does anyone dare ask how much his hats weigh? LOL
Yes - it is a factory OEM tinted safety glass roof (frameless) from a V8 Esprit. It fits on my 88 but the gasket needs to change. I added foam to it to allow use with my existing composite roof gaskets (shorter height).Question, when you say glass sun roof ,is it really glass or is it plexiglass. I have a plexiglass sunroof on my esprit, I would like to know if there is glass glass sun roof also ?? Thanks Dave
Check out my solution to this that allows use of both tops without changing the original composite top seal:Don't forget that the glass roof requires a different weather seal (higher and heavier :facepalm )
Hey, every pound counts - add lightness, yada yada!Interesting information but I don't think the 2.6 lb. weight difference is going to come into play when somebody decides which roof to put on.
I have both and even here in hot sunny Florida I prefer the glass roof which is heavily tinted and doesn't seem to make the cabin any hotter than when using the composite roof especially as it gives you more headroom and makes the cabin seem brighter and more spacious.

Glass. Not sure why yours would be plexiglass?
The first Stevens "glass" roof panels were indeed a sort of plexiglass or plastic. It was found that they would "bulge out" after exposure to the heat. So later cars were fitted with an actual glass roof.
Just searched for the changeover points, couldn't find them online or in my '88 - 92 parts book. I'm sure someone else will chime in...
EDIT Thanks Jim!
Repasted here with the update - verified as XXX Lotus Glass Assembly 43R-00014Update on my Esprit roof weights:
