Life Expectancy of Acrylic Windows

[ctva]

I’m replacing the bonding on a Jeanneau Sun Odyssey that is 20 years old.

Question is should I bight the expensive bullet and get new ones at about £360 for two, or just rebound the old ones which I can see no faults in and are relatively scratch free?

If they are still clear and not crazed after 20 years then that's rather impressive and therefore rebond them ..
Why waste money on something that's not needed

There are different grades of acrylic. The Perspex brand of acrylic has a 30 year guarantee against outdoor weathering whereas some will craze and discolour after 5 years. You obviously have a good grade! Just rebond your existing hatches.

Are you sure they are Perspex? I have a Jeanneau Sun Osyssey. I have actually replaced one of the windows. With a genuine replacement from Jeanneau. I’m pretty sure it’s polycarbonate

It would need pretty clever coating if it is; polycarb clouds quite quickly under UV.

....... polycarb clouds quite quickly under UV.

Actually, as in my post #3 regarding acrylic, it all depends on the grade of polycarbonate used as to its UV resistance. With the correct uv stabilisers added to the polymer it will have a long clear life. Car headlights are a good example as most manufacturers specify grades that will stay clear for at least 15 years and probably a lot longer.

Thanks for the info. I've checked with a Jeanneau agent and they confirm that it is acrylic, not polycarbonate.

As a separate question, can anyone advise on what paint (silver to simulate an aluminum surround which also acts as a UV block for the bonding agent?

There are silver aluminium paints specifically for painting butyl flat roofs to improve heat resistance, should be durable enough but i suspect you might have to buy more than you need.
