I am sure that this question has been posted many times, but I’ve been unable to find it in the archives, so sorry in advance. I have a 30 year old house with original aluminum frame sliding windows. The windows drop into a vinyl extrusion top and bottom – like those unfortunate “sash less sliding glass windows also popular in less expensive homes of the 1970s. The window is made up of four overlapping panes and “seal” against a slightly different extruded profile on the edges, a flexible vinyl “wiper” seals between the sliding panes. The windows are sturdy enough, and although only single pane, don’t seem to be too cold…yet.
I live in Canada and it has dropped below freezing and the inevitable condensation that forms on the inside of the outer sliding pane has started to freeze. I am sure that this has gone on for a long time, as the frame shows signs of moisture discoloration, mold – but not yet rot. What can I do about this, hopefully short of replacing all the windows? Thanks for any advice.
lots to learn
