    New pane.

    Misting in DG units is as inevitable as death and taxes. This is because the separator has tiny holes to allow the air trapped inside to be in contact with the silica gel, which is inside the separators. Over the years with atmospheric pressure changes there is a tiny movement of air in and out of the gap and eventually the silica gel becomes saturated, at which point moist air is entering the unit and eventually condensation will begin to appear.

    The double glazed units have been in 25+ years, south west facing windows get all the weather so Globalti it looks like its change time.
    Never knew there was silica gel in there

    Moisture in between double glazing panes, can it be removed or is it new pane ?

    in theory you could have the glass unit disassembled and a new spacer with new desicant. In practice, not worth the hassle.

    Glass units are cheaper than you might actually think

    Will measure up and price up.
    Annoying thing is one unit has dried out over summer but its left a nasty load of streaking.
