We moved into an old school building (built circa 1880) that was converted by turning the each of the 2 high-roofed halls into 2-storey accomodation. The roof spaces have been left with the original timbers. At the end of each of the halls the gables have these old fashioned ventialtion openings as pictured below.
They have been left in various states accross the building. One is completely open, one is open but with a wire mesh over it, the other two have been stuffed full of loft insulation wool.
What is the correct way to leave these openings? I assume they need to be there to provide some level of roof space ventilation, but leaving them completely open means the wind howls through the roof spaces end to end and an awful lot of heat is lost, it also provides an opening for brids/rodents. At a minimum I think they should all have wire mesh over them, but is there also a best practice to insulating them against the elements while still ventilating the roof space?
Thanks.
