Draught (Draft) from ceiling through recessed lights

rebelbuttmunch · 17 Nov 2009

Hi

I've a kitchen extension and it has an apex roof. Ive got a wooden ceiling on the inside.

There's a fierce draught (draft?) coming in down from the recessed lighting. I'm a little concerned about lashing in expanding foam in between the ceiling and roof, and thus isolating the recessed lighting, due to the heat generated by the lights.

I was thinking a possible solution would be to invest in LED lights instead, then I could go for the expanding foam, as they wouldn't be so hot.

Any ideas?

Thanks!

Hello.
Would fitting LED lamps stop the draft ????
I would strongly advise against using expanding foam anywhere near the lights.
Would these be of any use to you ?

Thanks Ed.

Interesting devices.
I was thinking that the LED or other fluorescent types of lights wouldn't get hot, so it would be ok to use the expanding foam near them. I wouldn't be putting the foam actually on the device anyhow.

Having similar green intentions at the moment, I'm replacing my GU10's (50W) halogens with 11W spiral tube bulbs.....illumination is instant and heat production is minimal although I'm watching it closely. John

Do you have access to loft area?

rebelbuttmunch · 19 Nov 2009

I do have access, up to my wrist

Its an apex roof on the outside and the inside. I reckon there's 30cm between tiles on the outside and wooden slatted ceiling. At least thats the depth of the recess that the velux window is in.

Does the roof have a felt underlining?

Yes, I can see it flapping along one side of the extension, into the gutter. (The other 3 sides being composed of a joining (neighbours)/joining(my house) and front (apex)

You could replace the lighting with bathroom lighting, the bathroom unit is sealed at the ceiling for safety so no gap for the draught.

Good idea. I also think that the sockets dont have any back on them. That possibly would help. I was thinking of taking the faciaboard off and letting loose with expanding foam. Bad idea?

You would need gallons of foam to fill the void you have.

I am having similar trouble and posted in another thread as I did not see this one - however I cannot get into the rood void which is only 13 inches deeps anyway.The downlights let loads of cold air through from the ventilated area above even though there is a 2-3 inch layer of rockwool up there but I think this has been dusturbed by the electrician putting in the lights - and there are 12 of them in the room!

I too am thinking of low energy bulbs to reduce any heat problems and had also thought of foam but now am considering just taking the fittings out and the pushing loads of rockwool up there before putting the lights back with low energy bulbs. Any other ideas though would be useful before I start spending loads on the new bulbs...

Am reluctant to start as the fittings keep breaking around the spring mount area when they are removed or retensioned - must have got a bad batch as I am sure this cant be normal - or is it?

I have been replacing my lv bulbs with led's, they give better light and only one driver is needed for up to 16 lamps. depending on wattage.

Led lights are good and give a good light quality.

Which trype of LED device did you use? - I have seen many complaints that light is much poorer from some LED fittings/
