I have a bog standard double-glazed conservatory, all the walls/door are
plastic and it has a sloping roof. The top half of all the walls/door are
double glazed, of course, with small rectangular opening windows at the top
of two of the walls.

I would like to fit a small extractor fan into the double glazing. I
smoke in the conservatory and not having to have a window open in the
Winter would make life a lot more comfortable for me.

Is it possible/practical to fit an extractor fan into conservatory double-
glazing ?

Can any of you incredibly knowledgeable people suggest any alternative ?

Any advice or assistance would be gratefully received.

It would probably be easiest to replace the sealed unit in one of the
opening toplights with a fan mounted in a panel of the same thickness -
that way you can just clip it in, and replace it with the original unit
if required.

There's a section in the FAQ about fitting a catflap into double
glazing, which should be helpful:

Alternatively, why not take this as an opportunity to give up smoking? :-)
