Drafts from fan in ceiling and ceiling lights

[TopCat1]

Can you please help me. My bathroom is very cold and very drafty, and it is due to the draft coming form the fan in the ceiling. We have the same problem coming from the ceiling spot lights in our bedroom (as you cannot put installation over them in attic).

My husband thinks that if he goes into the attic and disconnects the wires, he can safely cover with installation. Do you think this will work?

Thanks in advance

Disconnects the wires to the bathroom fan or the bedroom lights?

Both.

The fan in the bathroom is supposed to suck air upwards when you are in it (where does the draft come from?). You can wrap as much insulation around the point where it goes into the ceiling if you want.
If you don't want the spot lights, yes disconnect them - then you can cover with lots of (glassfibre) insulation.

Thank you so much for your reply. I'm not sure to be honest where the draft comes from with the fan, all I know is, the bathroom is really drafty, and when you stand under the fan (which is switched off as we have a window) the draft/breeze coming down from it is really bad.

The house is only 5 years old (we bought it a year ago). But we have major draft issues that we are trying to address.

I think it may be a part of the building regs that you are supposed to have an extractor fan in a bathroom - I'm fairly sure it is if your bathroom doesn't have a window.

You can buy fans with little shutters in, that stop airflow when the fan is off. (Have a look on screwfix, that's where I got mine) I'd think one of those would be better than not having a fan, but that's just MHO.

I'm surprised you get drafts through your lights, they are usually reasonably well sealed. All our ceiling lights are.

Correct, Catso - there's nothing in BR that says you need a fan if you have an opening window.

I have upstairs ceiling lights and they let draughts through because they have ventilation spaces either side of the lamp holder, which I assume is to keep the bulbs from overheating. I have been in lofts running telephone wires and there has been fibreglass insulation laid over the back of spot lights between the joists, and the light from the rear of the fittings was lighting up the loft with a pink colour, very nice, but the insulation was red hot. fire hazard or what? this was a new house, so the building inspector must have agreed the fittings and known the loft would be insulated, so perhaps the insulation is guaranteed non inflammable?
