 Perspex Windows

I ran a search but didn't find what I was looking for.
I've heard of ppl using Perspex for windows instead of glass to lighten a car but I have a few Q's:
Is it Street Legal?
Is it stronger than Glass?
How much lighter than glass is it?
Has anybody here done it?
and finally
Any ideas on $$$?

Probably not. Ring the RTA.

No.
It doesnt smash as easily, but it bends which decreases the stength in the roof of your car if you roll it (hence why its probably illegal).

For the same thickness, a lot lighter.

i wouldnt recommend this, although lighter its a poor mans window..
i doubt it to be street legal very very very much.
also with perspex youll get a scratchy cloud like appearance in it after not too long.. plus haveing the windows moulded would be an absolute fortune.
id stick to glass.

Unless you are american, which i doubt, then its not called Lexan at all. Perspex and Lexan are one and the same, its like spelling Colour and Color.
Anyway, perspex/plexi/lexan windows are quite light for what they are, and if they are on fixed 1/4s (like sprinters) then they are quite easy to do. Simply 1-2mm perspex sheets can be cut to size and siliconed in place. Normally ill add a couple of rivets around the edge to just secure it nicely.
Sheets of perspex are around $15 and can do about 8 windows. Or 4 pairs.

lexan is supposedly bulletproof hence its used in racing. Perspex being bulletproof is news to me.. we used that stuff in design & tech at school to make absoloute crap. Theyre both types of plastic but I always thought lexan was a denser/special grade?. Theyre the same?

Would it be legal to run on the rear 1/4 windows/hatch window?
I'm thinking of what to put into a fibreglass hatch. I wouldnt think a heavy pain of glass could be supported.

Why bother putting glass back into the hatch. The glass is the heaviest part.
A 1-2mm thick sheet wont hold its own weight over the size of a hatch and will have to be reinforced. The usual way to do it is with 1mm alloy plate along the inside.
The 1/4windows are fine without any reinforcement as gravity doesnt have as much of an effect.
Completely not road legal though, then again neither is a fibre hatch.

I don't want to put glass back in there  that would defeat the purpose.
But I was thinking that to a police officer giving the car a quick once over a fiberglass panel would not be obvious. Well not nearly as obvious as a lexan rear hatch window.
