Re: Lexan Window Thickness
I would use 1/4 inch. Pretty tough stuff. I think 3/8 inch Lexan will stop a .45 ACP round point blank.
The way that window broke would indicate that it is not Lexan, but rather is acrylic. Not the best choice for impact resistance.

Yea. Couldn’t have been more force than an average guy’s punch.

What do you think about tempered and laminated glass?

The only advantage I would see is that would be more scratch resistant. But the impact resistance of Lexan is greater, and it may be less cost. I've not had any problems with the plastic windows in my lathe or mill. The lathe is 30 years old and the windows are still fine, but I don't know if they are original. The mill is only 2 years old and I know they are original. Not sure what the material is in either of them, but if I needed to replace them it would be with Lexan.
Re: Lexan Window Thickness
I plan on upgrading my to 3/8 with new bolt in pieces. I can readily get lexan, just haven't gotten there yet. Just would make me feel way safer.
Re: Lexan Window Thickness
Lexan, NOT glass and NOT perspex.
1/8" or 3/16" would be fine. It's a window, not a crash barrier.

Re: Lexan Window Thickness
Fadal uses 3/16 Lexan you could also use 1/4 if you want even better. Fadal at first did use Tempered Glass on the first version of Full enclosure sheetmetal 1988 (you dont see many kinda rare but they had actual sliding doors on sides not the pull out panels). They went to Lexan when one of the Tempered panels shattered at a customers. Customer said "I was watching the part being machined and then all of a sudden *POP* the Glass disappeared"

Yea that’s why, if it were the route I was taking, what have used the *laminated* tempered glass rather than just standard tempered glass.

I’m certain that all walls around the machine have to be “crash barriers” even if it’s transparent.

Re: Lexan Window Thickness
I installed 3/16" Lexan from local homeless depot because that's the thickness that was in there.. I think 1/4" will tighten up in there better because the 3/16" clamped okay but not real snug. 1/8" will be a very loose fit.
