There has indeed been a lot of discussion on this issue and even the Mods have suggested leaving it alone until something positive is published. So far there has been lots of comments but these have often clouded the issue rather than clarifying it.
Just bear in mind that the primary issue concerns a German manufacturer of caravans and motorhomes recalling windows made by a Dutch Company over a long period of time. No one has suggested that the actual material, which is being named, is at fault, merely that the manufacturing bonding process has not been as it should be on possibly a large number of windows. Any faults from windows from the UK manufacturer supplied to UK caravans and motorhomes should therefore not necessarily be linked as these are separate Companies. As you can see it is complex and until a clearer picture evolves, I suggest leaving it alone. Litigation is also a possibility and therefore comments here would not be helpful, for either side.
