Phil,

      I take it that the box is to keep the noise
down ?  

Where are you getting the fan from ? is it expensive.



Regards,

Paul

Just vent it into the loft void...

...my venting plans for the garage are that the 4" pipe coming up
through the main bedroom will enter a large sealed box (roughly 0.75m
cube) lined with thick sponge or foam and then lightly stuffed with
Rockwool. 

Coming out of that will be a 6" pipe to a 6" centrifugal fan
(there is a
lot of flow lost in the rockwool filled box) ...
