Have any of you had direct experience of fitting one and did it
do all you expected of it ?

Here is what you might think is the silly part of the question .
If the louvres are sealed up to make the process work natural light
is cut off to the bell chamber . Is there a variation of the sealed
double glazing unit which does that job , lets in light and for
the benefit of those interested in conservation etc - is quite
invisible from ground level ?
