Crazed perspex windscreen

[Monza]

I have a curvey perspex windows on the boat that have crazed with little fine lines from too much time in the sun. From what I've been told, these lines can't be removed. How easy is it to get new ones cut and fitted as the windows are quite curvey and bend from the front screen around to the side ?

It depends on whether you can bend a piece of acrylic sheet around the curve or not. If you can, then buy yourself a sheet of 4.5mm acrylic sheet (get a tinted sheet) and make your own new panels.

If you cannot bend the sheet without it cracking or hazing then you may need it professionally done. OR..... you may be able to do it with a heatgun.

Without being there to bend a piece and see what happens its hard to advise.

Needless to say, if you need it done by a pro, strip the screen, pull out the piece you need and give that to the screen maker. They can then use it for a mould, make a new piece and charge you for the work they have done. You then refit it and the job is completed a lot cheaper than delivering the boat to them and saying "fix it".

Mate, there is a place AMW in Cameron St Clontarf thats all they do is marine windows. Give em a call tell them what you have a take it from there. You may be surprized how inexpensive it is.

My money says its a Quintrex.

Well known problem, get it on warranty if still in it.

Go with lexen it bends better and is stronger than standard perspex

I would definitely not use Lexan. I have used both Lexan (which is polycarbonate and Perspex which is acrylic) before and Lexan with a tint and scratchproof coating is very expensive per 2400x1200 sheet. Last check a sheet of Lexan (as described) was around $300 trade and a sheet of acrylic (aka Perspex or any other trade name for it) was around $130 trade.

The scratch resistant coating on Lexan will still scratch more easily than acrylic.

The only benefit to Lexan is that it can bend around shapes that perspex cannot without being heat moulded.
