I have absolutely no where in the kitchen to fit an extractor fan.
Walls on either side of the door and windows is about 4". Above the
windows, can't be fitted there, because of the lintels.

Is it possible therefore, to fit an extractor fan into double cglazed
windows.

I know I can't do it, but if I tell the double glazing supplier what
I want, is it possible ?

Yes, my MiL has that in her kitchen for the same reason. T'was a local DG
supplier that installed it.
