Hi all,

This summer I installed a batroom extractor fan to reduce the
condensation when showering, etc - particularly in winter.
It's one of thos B&Q / Greenwood kits, ie through the ceiling to loft,
flexible pipe, out through soffit board under the eaves.
It was only £23 as I bought the version without "run-on" and operate
it simply from the bathroom light.

It seems to be doing a good job, but during the recent windy weather
particularly, I feel quite a draft entering the bathroom. I think this
will lead to significant heat loss and a less than hot bathroom which
I like.

Does anyone know if there is a "louvre" end cover that I can buy on
its own and ideally has the same 5" hole and screw footprint as the
B&Q/Greenwood.
Will the fan be powerfull enough to suck open the louvres if installed
at bathroom end, or blow them open if installed outside under soffit ?
Which end is preferred ?

Thanks.

David
