FWIW, I was told by a local glass shop expert that, although Lexan scratches more easily, it is preferred if you are concerned about weight (like a crew member) cracking the lens. I have two hatches (of five) where this is a concern. According to this expert, if you are not concerned about the weight-bearing capacity, plexiglass will hold up better over time.

Dave, when we did Perception for the second time we used 3/8 cast polycarbonate. I had Rob at south shore make them for me as the previous replacement damaged the frames and had used 1/4" extruded poly, which had cracked, and he had the original templates. We had them installed and the frames repaired - all is well 5 years later! You can get the material from Plastruct Polyzone in Beamsville, I have used them for the hatch board and slider.

Subject: Stus-List 33-2 portlight material

Evening all - have searched the archives and have found a great deal of info on adhesives and the replacement process, however not a lot on the material.

I understand the windows are acrylic (plexiglass) can anyone please confirm the thickness? (Mine are leaking, but still installed)

I know that some have used uv and scratch resistant polycarbonate . (Can’t locate the post). Any thoughts?

Is the material used for the portlights the same as for the (now quite crazed) hatches?

Many Thanks in advance.
