We have two back doors, both in different rooms, both with about 12 panes of
6x9 glass (or so) in them.

There is nothing wrong with the doors apart from they need a paint and some
of the glass is mismatched.
I thought I'd strip them both down, and replace the glass with new clear and
wondered if I should 'upgrade' the glass in an effort to make our house ever
so slightly warmer (I have an ongoing project to remove draughts etc).

Is it worthwhile? If so what sort of spec glass should I go for?

TIA

You will be required to use 6mm glass (it probably is already unless it's
quite old). I presume you are thinking of K glass like the use in double
glazing. Not sure how available that is and whether it would make a
difference worth the price if not used as part of a double glazing set up. A
curtain across the door(s) would be cheaper and a lot more effective,
jeeping heat in and draughts out.

Nope! The requirement is for "Safety Glass". Could be 4mm Toughened or
Laminated.

Low E glass coating on a single pane would have no heat-loss reduction
properties at all. It must be inside a sealed unit for the reflective
effect to work.

The only thing that will make a worthwhile difference is double glazed
panels. Solid glass - no matter how thick - will conduct the 'cold'.

Go read the regs carefully.

6mm is suitable for panes of limited size.

In detail panes less than 250mm wide beween glazing beads (and with an area
not exceeding 0.5m^2 but you never usually reach that) can be of 6mm
annealed glass.

Above this size, safety glass is only required in windows where the glass is
below 800mm from the floor and, in doors, where it is below 1500mm from the
floor.

I believe "outbuildings" are not covered by these regulations - at least I
was able to buy a ~1m square sheet of 6mm for my old garage. I should say
this replaced a sheet of 3-4mm glass which my son had sent a football
through. I'm not a particularly nervous or sensationalist type when it
comes to safety but, had I been stood at my workbench at the time I would
have been hospitalized given the huge area of the garage that was filled
with medium size shards of razor sharp glass. The 6mm probably wouldn't have
broken anyway and the weight of the glass would have limited the danger
area - I feel a lot happier behind the 6mm!
