I have several double pane casement windows with Truth hardware and they all have a slight draft coming from the side edge where the window meets the vinyl weather seal. The draft is not coming from the sash lock side but the other side. I can feel the draft and see a very slight gap where the window meets the seal. Is there anyway I can adjust it so that it closes tighter? The sash lock side seals fine but I noticed that when I push the sash down to lock the window it doesn't seem to close the window in that tight. I noticed one of the windows close a lot tighter when the sash is push down to lock the window in. You can feel it pull the window in and clamp tight when locked. Anyway to make the sash lock close tighter also? Any advice would be greatly appreciated.
