Small Shower Room Ventilation.

I was talking to a developer this morning. His son is a sparks. The two have installed a new 4 inch ceiling fan in a small upstairs shower room that has no windows. The building roof has been renewed recently and new breathable "felt" installed under the tiles. I had previously mentioned that the roofers could install a new roof vent for the fan ducting, but nothing has been done about this.


The developer says that the son advises terminating the air duct in the loft onto a bucket to catch moisture, which I said was not acceptable.


Bearing in mind that the new roofing "felt" (membrane) is breathable, is there any reason these days not to terminate the air duct directly into the loft space with no external grille?

  • My mother had an old warm air gas heater in her kitchen which warmed the whole house. It needed air from the room to burn properly. The single glazed wooden framed kitchen windows has two metal trickle vents installed above them. They had anti insect gauze inside them. A gas fitter that we called once to service the heater said that he could not recommend the ventilators because people put rolled up newspapers into them to prevent draughts. We promised not to, and he was a bit happier. But in very cold weather we just blocked up one of the two to prevent cold draughts. I think that fresh air leaked in via the extractor fan which ran through the wall.
