Busted cabover window - UPDATE- Repair complete

[portscanner]

I had a crack in the cabover window from some time and with all the rain it has finally started to leak, so I got to replace the glass.

Has anyone replaced the glass with some thing other than glass? I figure lexan or plexiglass would scratch easy and would look poor in a short period of time - but I was thinking of something that was not transparent - that would be stronger (or at least less brittle) and be a better insulator - like a fiberglass panel with a foam or plywood backing?

I can get a piece of Lexan from the local big box store. I can easily cut that, as I already use Lexan for other items in my business.

What is the putty they use to seal the window into the frame? Is that just butyle?

I was just reading up the subject, i'll pass this on to you. It appears that this company will custom replace auto glass or any type of glass with whatever you choose.
It might be worth it to give them a call for their opinion as well.

What would be good is a double pane Lexan window cut to fit. It would still be lighter than glass and less prone to crack.
I'm in line for someone to come up with this type of replacement for my front glass (cracked in a hail of gravel from a speeding triple trailer log truck on a trip to AK. Hasn't leaked..... yet.

I replaced a window in my TT with a tinted acrylic. It is a lot tougher than glass, but yes, it will scratch.

I would go with Lexan. It is very tough material. I have worked with and tested Lexan for some window applications.

In one of the tests I took a fire extinguisher and slammed it into the Lexan window as hard as I could. I hit it so hard that I knocked the entire display over onto the floor.

After righting it again, the Lexan was perfectly intact and there was only a small mark on it. The stuff is amazing!
