March 27, 20215 yr Hi, We have gravity shutters externally on our new build which go from the bathroom extractor fan. Every time I go outside they always seem to be easily opened and are open with very little, if any, wind. I've noticed that the room beneath this vent (the vent goes from bathroom through the partition between first and second floor) gets very cold as a result. Any tips on what to replace it with and/or how to stop the draft into the bedroom below?
