When we sit in the caravan and look throuh the front window on the right hand side, the plastic appears to have delaminated on the inside between the panes. The window is smooth on the interior and the exterior. Any advice would be appreciated please. Thank you Dafydd and Beryl Williams

I had a window delaminate across the bottom edge, which of course meant that the catches only held the inside pans securely, There are a couple of companies that will repair or make new for you,
here's one https://eeco-ltd.co.uk/ or like me you can take out the window, separate the two panes, clean up the glued area then fixed them back together using a low modulus clear silicone sealer, that was two years ago and it still seems solid.

Dear Dave
Thank you for your help, unfortunately, our window problem is not the same as yours. We have tried to include two photos but as they have had to be taken inside the barn they are not too clear, but hopefully you may be able to see our problem. If you have any suggestions we would much appreciate your assistance.
Thank you Dafydd and Beryl Williams
