Recent fashion about double glazing for me just scam.Under "double glazing" name Australians forced to buy windows which have special gas or vacuum between glasses.
Which cost fortune because you have to buy new frames.
In Europe people use double glazing for at least 150 years. Without any gas/vacuum. So window costs about 30% extra, but much efficient compare with single glass.
And noise also reduced, not only heat.

Here how I installed second glass on existing timber frame:
I did not want to use router, which actually would deliver better result. So I just put new glass on top of the frame and used "Clever Closet" bracket from Bunnings to hold it in position. I cut the bracket in shorter pieces. It has "step" around 4mm, for 3mm glass fit into this "step" exactly. White electrician adhesive tape was used as a gasket, to avoid cracking glass in points of contact.
Silicon was applied around as seal.
Also I drilled tiny (2mm) hole on side of the frame, to ensure the volume between glasses can communicate with atmosphere. I filled it with tiny piece of glasswool, to keep insects away.

It is how I improved aluminum frame in bathroon. Problem with aluminum: it provide heat very well. So double glazing no so efficient, if you do not cover frame also.
I used plastic "board" from Bunnings, "black" one. I saw also "white" and "blue" ones. It about 4mm thick, has thin walls ans filled with air. So perfect from insulation point of view. "Black" also reduce heat and provide privacy.
I lost view to timber fence which is located at front of by bathroom window... Pity...
First photo - original window.
Seconf photo - plastic board from Bunnings.
Third photo - result. The boards were cut and glued by clear silicon to the frame. You can see two tiny vertical lines, where there are small gaps.
Fourth photo - curtains down, plastic cannot be seen. It looks like usual "tinted" glass window.
Last photo - name of plastic.
Probably it exist in bigger dimensions, so whole window can be insulated without gaps.

And finally, same plastic was used on usual sliding window. There is about 6mm gap between frames in standard sliding window. Plastic board 4mm thick. So it fits. I used clear silicon.
Silicon can be easy removed if insulation will be non needed.
Plastic board looks like "zebra", it is a reason why difficult to to see it under blinds - just one more set horizontal lines.
I just glued plastic board on top of glass from inside the house. After I put blinds down it looks like tinted glass. And yes, I again lost view at old timber fence...

Australia has plenty of gas and even sell it overseas, so we pay fortune for heating. From point of view government it is perfectly logical, I just cannot get any logic in this tale...
As soon as Labors will get into office they will increase prices for energy even more. According to Greenies energy from solar/wind is free, so since 2007 we pay for electricity from these sources much more then for coal.
Insulating is already important and will be even more.
For glazier my ideas may be source of income: you can install second glass using existing frames in old houses for very small price compare with brand new "double glass". People will save money on heating/cooling.

I do not have it.
I am from Europe, as I remember I had condensation there it on very rare occasions. Only if weather was VERY cold. As soon as weather warmer - condensation gone.
And condensation happens only in corners of windows, it is not really visible.
Australia always has "plus" temperature, so I do not think I will ever have condensation.
