Condensation outside tiriple glazed

You'll get that some times of the year more than others. The windows are so effective that the outer pane of glass is at or below the dew-point temperature (ie, not losing any heat from the interior) and hence on damp mornings especially, it will cause condensation. So as MicktheMan said - a good but slightly annoying indication that the triple-glazing is optimal.

There will be frost on outside of them during winter ! I think it great to see obviously no heat escaping

i assume you mean sub zero. yes of course it could and probably will. its a sign the windows are working well.

all windows will freeze up if its cold enough

We would be over the moon with that problem, our old double glazed back windows have to be wiped down every morning at this time of year or we'll get black mould growing on them. The newer double glazing in the same house is bone dry.

Waiting now 4 months on triple glazing to go in to replace them, hopefully with the same same eventual result as yourselves!

The external noise is likely airborne noise? and therefore the triple glazed windows will have no noticeable effect if there is air leakage through the rest of the structure fabric.

Looks like Timber Frame houses were a short-lived phase in Ireland, At the moment there are numerous housing developments being built locally and 100% are traditional blockhouses.

Brawn factory I hope you mean, otherwise I've been sold a lie about human existence all this time.

I hope they work out the issues around sound-transmission in adjoining dwellings and not just say "it's within spec!!" - that's a massive turn-off for any wooden construction.
