Restoration and Windows

Recommended Posts

So I’m in the process of restoring Barbarians decks, and have come to the windows. I’m keen to try and preserve as much of the original character of the yacht I.e I’m not trying to make it all new.

Have resealed the windows a couple of times over the last 20 years.

The first time with some sika, didn’t last long till their were leaks, the 2nd time with mastic which was great but that sticky non hardening mastic is forever easing out and sticks like STABlanket.

Those screws spaced every 70mm around the window don’t help, just 1 not right and water finds it’s way. Also restoring the aluminium frames is proving less than easy, has to be completely cleaned of all paint/silicon and all I’ll end up with is the same issues.

Having read the last windows topic, http://crew.org.nz/forum/index.php/topic/14097-window-replacement/?hl=window%20replacement

I. Would like to go down the same path but have 2 questions that members may be able to help with.

1. How many have had leak problems having implemented stick on windows ?

2. What neutral density of acrylic have members used allowing good light but some privacy.

The pix Willow put in the last thread look good.

'Bed-it' butyl tape.  As well as being leak proof, if you make a co#k up, and need to realign, then its no trouble to take off with a bit of grunt and do again.  Don't ask me how I know this!

 

I like your boat. looks  really good.  What design is that please?

Hi Replaced windows October 2018 Used VHB tape and Dow silicone. No screws and reasonably long windows all done on a marina in i day (Raven 31). Trip round the North Island over summer and no leaks whatsoever. Was warned against going too thick in the acrylic as the thermal mass and tendancy of material to pull away (tries to stay straight) can apparently cause an issue..

Getting with the current program.....

One thing I don't like about the Dow795 is I get slight

discolouration where dew/ rain riverlets run down the gelcoat beneath windows.

Like a smudge.
