I’ve got most of my walk on glass in .
From the photos you can see water ‘track’ lines .
They’ve always been there .
Cold to the touch but bone dry . Also the window internal up stand dry even in the corners where the track appears to run .
So am I being optimistic that it’s condensation ? ( we are below ground ) . Previously I’ve seen water dripping off the ceiling ( even before glass was in ) . Water still gets into the build on the ground as the end is open . So just wondering if I can blame temperature differences to explain this . Can’t believe it’s a leak - tested it at ever stage ....
Guess I need reassurance 🙄
