We have cheapo aluminum window frames, since that seems, for some reason i can't understand, all that gets used in this area. They're double-paned, but the frames aren't sealed, so the frames have Zero insulation value.
What I'm wondering is whetehr I can get away with using silicon sealant on the outsides, where there are various gaps and openings, so as to give the things something resembling insulation value.
If that can't be done, is there anything tat van be applied over the outside or the inside of the metal that would offer some sort of insulation value?
