Replacing the "long window" with seperate windows...

farmer boy says:

Hi guys,
I was just wondering if it is practical to install separate windows? I definitely have a leak and Neil Rothwell has put me on to a good supplier of a new piece of perspex but If they are such a problem would it make sense to buy some new replacement windows for each hole...
Anyone done it?

I have a leak in the windows on the starboard side I wasn’t intending to replace the whole thing but rather undo all of the screws clean the Perspex apply some sealer and careful put it back. There is an article on the website from Geoff Marks about window refits –the screws on Portia’s windows are all located into cups on the inside so I don’t expect it to be so difficult as Geoffs project

Generally people go the other way 3to1 .. 6 holes 3 times the risk of leaks
And of course being on top theres less risk of being stove in by huge mountainus seas! and you would be left with lots of screw holes,,
People who have used sticky squidgy tape seem to have good sucess..
We used self tappers without. Remember the black perspex expands length wise and if solidly secured belge in between lifting off...drill larger than the screw shaft. to allow movement ...

I tried and failed twice to replace the big windows on Snoopy463. Always got leaks. Eventually opted for separate ones with rubber surrounds. You can see how it was done on Snoopy463's photostream page 2. There's lots more about windows on www.achillesyachts.co.uk/page7.html

There has been a long discussion about refitting windows somewhere on here you really need to make oversize holes in the perspex for the screws so that there is room for expansion when the perspex gets hot. This is why they crack, the screws invariable have been put in too small holes. You also need the correct mastic and neoprene strip, try Eagle Boat WIndows they were very helpful when I spoke to them at the boat show a few years back

Interesting I am going to attempt to vac bag my new long windows on this weekend. I am aiming to have no screws. I have all the correct uv sika and correct primers. With a good seal the vac system will apply 200 bar of pressure. on the screw note i have learnt from past experiance do not counter sink the screws, always use pan heads. As you say the perspex expands this then cause a wedge effect on the counter sink hence the fact you get cracks around the screws.

i will send you the pics of my windows should they work!!

Adding to existing discussions and keeping down the number of new discussions makes my life much easier maintaining said index, but please don't take this as an instruction to stop contributions or asking questions, after all that is what this site is all about.
