andybarrett1 Posted June 8, 2021 Report Share Posted June 8, 2021 Thank you for reading I am in the near future looking to replace the seals on my windows. Take them out clean them up and replace .... My question is what would be a fair thicknes for the seal, Midland are sugesting 12mm wide by 12mm depth (Seems a lot) Caldwells... Who made the windows are suggesting 16mm Wide but no depth suggestion. Any guidlines here ? Metal Hull / Caldwells hopper type windows Thank you again for reading Andy Link to comment Share on other sites More sharing options...
GUMPY Posted June 8, 2021 Report Share Posted June 8, 2021 (edited) Do you mean the seal between the window and the boat? If you mean the actual seal in the window that the glass is in then I bought mine from Caldwell's so I knew it would fit. If you mean the seal between the window and the steel then butyl tape is one way or something like THIS Midlands offering will be the soft squidgy stuff that absorbs water Edited June 8, 2021 by Loddon Link to comment Share on other sites More sharing options...

stuart Posted September 20, 2021 Report Share Posted September 20, 2021 (edited) Hi @andybarrett1 how did you get on with the window sealing? I also need to do this. The windows were originally fixed using foam tape which failed after a few years. I replaced with butyl tape, which eventually dried up (a few years later) and cracked! As I've a lot of boat painting to do and need to remove the windows a couple of times, I'm thinking of going back to a tape. Perhaps an EPDM tape like this one. https://www.toolstation.com/stormguard-epdm-weatherstrip-p-profile/p23386 Edited September 20, 2021 by stuart Link to comment Share on other sites More sharing options...
andybarrett1 Posted September 20, 2021 Author Report Share Posted September 20, 2021 I just got the original tape from Caldwells . I got to do one side ..... All looks OK so far Only thing is as the tape settles I did have to nip the screws up very very slightly as i did get a little rain ingress the day after All good now :-) Andy Link to comment Share on other sites More sharing options...
