Lexan Windows
 
Looking for some input! I am gutting my doors and windows in my Civic..

The factory side glass is about 3.5mm thick, anyone know if there is any required thickness or recommendations for how thick it should be?

Not doing the windshield

I use 1/8 inch. Works fine. Just trace your glass window on tbe lexan without removing the protective cover, cut with a jigsaw, and you are done. Forget rolling anything up and down. Doesn't work with a flat panel. I use two long machine screws to hold the lexan window up where it belongs.

Thanks Gary..

So no rule on mandatory thickness?

I plan to completely remove the glass in the front doors in favour of window nets.

Lots of work being done on the Civic this winter

Grant, the replacement of glass windows is permitted in the rules, section 1.4.5. There are no minimum thickness rules for the windows in the doors or the rear window. Most people use 1/8 inch (3 mm.) for this. However, if you change the windshield as per rules 1.4.6 & 7, there are several specific requirements for that, including a minimum thickness of 6mm.

I once replaced the windshield in an ice race car with Lexan. This did not work well, as I did not pay the really big bucks for the kind that won`t scratch. The result, once the wipers had been used, was a mass of tiny scratches. Horrible to drive into the sun. I won`t do that again. Treat your Lexan windows with care.

Finally, no doubt you are aware of the PIP`s for window modification as set out in C.13, but I thought I`d mention it. Although, now I think of it, you have a cage and probably will be using race weight. Regardless, best to read the rules yourself, as always.

I agree, do yourself a favour and buy the good stuff for any window you will be looking through (e.g. windshield, back window).

Ask me how I know !!!

be advised if you ever plan to run your car in race and use lexan in the front there is a 1/4 inch thickness requirement.

Stupid rule when the factor glass is 3.6mm 1/4 inch is over 6mm not even sure that it would fit??

Regardless I will not be doing any wheel to wheel with this car!

Not too stupid really, even Chumpcar requires 3/16". Windscreen is a big part of what keeps the driver safe from debris in event of incidents occurring in front of you; Lexan isn't as tough as auto glass given equal thickness. Plus Doug is really just trying to help.

Barry, it was nothing against Doug! My point is the factory glass is the same thickness and Lexan will not shatter like OEM Tempered Glass

I would never Change the Windshield out for two reasons! Lexan scratches easily and I know the OEM Windshield is part of the structural integrity... Even though my car has a very well built cage with 90ft of tubing in it

Factory windshields are laminated and don't shatter like side/rear windows.

Yes I am fully aware of the windshield being Laminated, was talking about all the other glass.
