I want to replace the two windows in the coach roof by the mast as they have crazed and leak. I think the leak is due to them being trod on and as they seem to be quite thin they bow under the weight thus causing the seal to part.
My first thought was to replace them with thicker acrylic which would bow less if stood upon but it would be necessary to have the edges chamfered so that there was not an edge to trip over. I guess this would be quite expensive.
Another idea might be to get replacements made in toughened glass , I have no idea what this would cost though.
I know that the windows are not designed to be stood on, but there location make them difficult to always avoid.
On a similar topic I have a small leak in one of the side windows despite tightening the retaining screws. BTW it seems as if the screws are self tappers as some won’t tighten?
Any advice on these topics would be welcome.
