We were working on boler
Windows last year, but that got stalled by the
trillium belly band repair.
Just getting started again on the boler 17. We found crud blocking the weep holes for the windows - weed wacker string worked for us. We were going to just switch the weathered outside gaskets with the inside ones but found that out the glass panes in the windows were mainly mounted with butyl tape which had crud between the glass and the metal frame in places. So had to remount those.
Ended up buying new gaskets, only have them installed on one window so far. Did remount the windows with butyl tape. For the screws holding the window clamp ring, some came out easy, some broke in half and some didn't budge. Our Windows are anodized aluminum, so l was careful about cleaning them so l didn't scratch the finish anymore than it already was. When you pull the Windows off you can see the window model number, which is handy to ordering gaskets.
Also removed tons of calk all over the place.
And once you take the clamp ring and screws off the window it is just the butyl holding the window on.
