The time has come to replace my saloon windows.
They are leaking (come fully away at the ends / corners) and are fairly heavily crazed.
Will do the standard smoked acrylic.
But how to install them?
Who uses mounting tape? Like butyl tape or one of these Very High Holding tapes that are commonly used for sticking massive pains of glass to commercial buildings.
I understand MS polymer gue is the way to go. Does the specific brand matter? I've seen Quilosa MS35 from Glue Guru recommended. But ADOS MS Polymer from Marine deals is about half the price.
Two aspects to consider, these are Townsen style saloon windows with compound / eliptical curves. If I use a fancy butyl tape, will I be able to stick it down matching the window frame curve?
There is a slight curve of the cabin top across the length of the windows, meaning the middle sits flush and the ends sit proud. (I'm going to go and measure this with a straight edge tomorrow). It's something like 5-10mm over 1.8 ish meters. Can a standard 5mm thick acrylic bend to that? If I use a thicker bedding tape could it handle that curve? Or should I go whole hog and pre-bend the windows to match the curve of the cabin top? (note that it appears the windows have popped off at the ends because the last lot weren't pre-bent, and we've had leakage issues for some time).
Also, what is a typical thickness of the acrylic? 5mm? 6mm? It's an inshore Gulf cruiser, so I don't need Cat 1 cyclone shutters.
I like the idea of a bedding tape so I can just offer the window up to the frame and it sticks, then apply the MS Polymer gue to seal the edges and cove it up a bit.
Last time (done by my father) we used a foam tape as an edging to stop the gue squirting out into the interior (he doesn't know what sort, it was a sika product that came with the gue) and then used a bunch of sticks pressed between the lifelines and window to hold it in place while the gue set.
I've seen various bedding tapes at Auckland Glass, but there are so many types, widths and thickness I get a bit overwhelmed. That, and I assume they are normally used it dead straight runs on clear windows, not compound curves on a boat.
Any advice greatly accepted.
