Vista window glass to window frame sealing.

[nickclifford]

Hi folks, I’m sure been asked many times before, so apologies. I removed the plastic inner window pane because of the clouding and debris etc but in doing so it’s created a leak in two out of the three windows. One is rather bad. Both inner and outer vista windows sit in their own channel so not sure why this happened but now I need to try sealing more from the outside. Any thoughts on best sealant to use would be most appreciated. Thanks

Mine are held in place and sealed watertight with sikaflex 221. I took both panes out entirely to clean them and glued the outer pane back up with sikaflex. Still haven't reinstalled the inner pane yet, but it's been watertight for a couple years this way.

Thanks, my inner pane was plastic and i had to break to remove, so they are history. Being that inner pane sat in own channel was surprised that the outer glass seal was weakened and started to leak

Unless the gap is huge, I would use Captain Tolleys.
