I have this vent into a bedroom in a flat I am renovating. This room can get quite drafty, especially in winter and I'd like it to comfortably be a bedroom. Is there any way I can seal it up or put in some kind of insulation so that room doesn't get quite so cold?
I am also interested to know if there are regulation in the UK (Scotland) that would prevent me from doing this either to my own home or a home I may rent out at some point. And, if so, what can be done then?
