I have two layers of sliding windows (original windows from 50 years ago). The two windows are separate, so one can be taken out while retaining the other. The ensuite bedroom faces in the direction of train tracks, but the noise is not too bad even with the windows open and totally acceptable with them closed (I appreciate the larger gap between existing panes is superior to double glazing for noise reduction purposes).
For both even better thermal and acoustic insulation, should I retain the inner sliding window, which the installer said I could do if I wanted? Would there a significant benefit with retaining it? Or will it just be an ugly nuisance to access the new uPVC casement main window?
Condensation is an issue in the room, so with them closed the trickle air vent, if opened might mean damp air gets exchanged even less although there are vents in the existing sliding window frame?
