In Reply to: LEXAN WINDSHIELDS - BEST or CRAP posted by John E. Talley on January 30, 1999 at 15:25:57:
I don't know about windshields but I replaced the Plexiglass windows of my 1968 Islander 29 12 years ago with darkly tinted Lexan and have had no crazing or cracks (unlike the previous clear plexiglass - which I suspaect did not have UV protection). I think UV protectorant is the key. Buy the way I used to work for E.I. DuPont in the 60's - and and Lucite was once DuPont's plexiglass before they switched the Trademark to stand for their latex paint, and then sold it off.

: Hello,
: Currently we are using Lexan for the windshields on our "Tempest". They have been in place for 3 years and have now sucumbed to the elements. We had used Lexan on our "Double-Eagle" and after 9 years we have yet to develope a problem. Granted, the angles at which they are subject to the sun are different , but I do not understand how the Lexan could deteriorate so quickly on one boat and not the other.
: I do not believe that standard glass could withstand the vibrations and structural flexing. Is Lexan the best choice for this semi-flexible application and are there different grades which would be more suitable for this application? If we did use glass, what thickness would be needed and how would we isolate it from the stresses?
: Thanks for your time.
