Six new windows are required for the alterations so current thinking is
to go for new throughout. First estimate for 12 windows and two doors
came in at 18K fitted. This afternoon was spent trawling round the local
showrooms. I'm not much wiser:-( The much vaunted narrow mullion
aluminium does not seem to exist. By the time they have put in the
plastic thermal break and endless folds for strength and appearance they
are as fat as uPVC.

Why replace the existing windows? Just fix them like for like if
they're misting.

Elsewhere, the architect has specified 4-20-4 argon filled. The existing
window rebate is much too narrow. Also new windows will be visible on
the frontage and jar with the existing.

Thoughts please. Does uPVC really stay clean and shiny for 20 years?

the gloss goes & it becomes somewhat uncleanable. If facing onto a
street there's also a slight risk of cigarette burns. I'd plan on a set
of windows staying for a lot longer than 20 years!

Isolated plot, set back from the highway.

With new PVC I'd go for external glazing. The advantage is that when
the sealed unit seals fail (not if), they don't mist up & don't need
replacing.

Please enlarge. I thought the only difference was whether the burglars
could prise them out.

Have you considered new durable species timber windows to match the
existing? (but with deeper whatsits.)

Not yet. This will be out last house and I am trying to avoid
predictable maintenance.

If you go for ali windows, beware of colour finishes such as powder
coating. Nothing sticks well to ali, lumps come off in time. They only
reliable way to colour ali is anodisation.

OK. There doesn't seem to be a raft of disgruntled powder paint owners
out there.
