You set them in by stapling them to the rafters so you staple them towards the mid position with the 90mm. I used them at my very last spot for wall insulation. They are doing a crap occupation imo since they don't kind an unbroken vapour barrier and inevitably gaps form.
So you are trying to blow absent individuals who have truly had these units mounted and expert the dissimilarities, While you are only accomplishing armchair observations.

So probably they do the job maybe they dont
That is definitely regrettable. There are lots of experiences of them Operating, and of some not Operating the place there were not any eaves vents. I have yet to find out our birds not turn.
