I am in the process of going through the same thing myself.
I have opted to use an acrylic screen
(Alexon). It is 6mm and flexible to the extent that I can put a slight curve on it.
(similar to perspex) is virtually unbreakable and has been used for security
screens and in prisons, and doesn't scratch or wear like normal perspex. I wouldn't feel comfortable using glass.
I am using a relative light weight stainless steel
frame - opting for this rather than aluminium, although more expensive.
The windscreen will be permanent and then I will have studs on the frame to clip a removable folding canopy/binimi. This way I have the best of both worlds - a permanent hard dodger
and the canopy that can be removed and stowed in fine weather
This is all to replace an old fixed canvas and perspex dodger
, which was a blessing in bad weather
but a curse when salt
spray got on the perspex and I couldn't see forward, and was not easily removed for fair weather sailing.
