Merry Christmas reindeer

Question about triple glazing please.

We had 13 windows, most about 1 metre square, including 2 patio doors as well. The softwood frames (35 years old)  were taking more and more attention and the units were misting up so we saved up and bought aluminium (reluctantly) insulated, with triple glazing, wide gaps and Argon filled, with the hope that maintenance would be reduced and that less heat would be lost. Seems to be true, one month later. Heat curve reduced on gshp so less heat into house despite frosty mornings, can reduce still further! snow

Question:
The outside of the outer glass layer can get really cold with dew forming on it. Initial panic that they were misting was untrue, thankfully. But is there a way to reduce this please?

not really  Roll Eyes You would have to dry the outside air or increase the internal temperature (raising the external surface temperature)!

I built my workshop with ex-demo double-glazed window and double doors. It came as quite a surprise to find frost on the outside like the stuff usually reserved for car windows. This would happen even with the wshop at 15 degrees all day long.
