I'm thinking about good quality triple glazed units in both cases. Am
I likely to see much of an improvement given the extra layer and the
passage of time?

The patio doors in particular are draughty anyway so I'd expect to see
improvement there. Also are any of the modern alternatives to hardwood
any good?


triple glazing has its uses, but not many. The gain over dg isnt a
lot. But your problems are evidently elsewhere. Draughts can often be
fixed with a bit of silicone, apply to the frame, place clingfilm on
the opener and shut the window/door. The silicone is then moulded to
the frame.

Don't forget to give the cling film a coat of cooking oil to act as a
release agent first though. It might also be a good idea to give the
window/door a thin coat, in case of creep of silicone.
