Bathroom ceiling with vapour barrier - shower light / exhaust fan

Hi all,

I am remodelling a bathroom and my wife has asked for a shower stall light, and of course we need a ceiling exhast fan. I intend to center the fan in the room, and I would have to add the shower stall light.

I have been advised that, considering the ceiling above the bathroom is the attic with blown insulation, and that I live in a cold, cold part of northern Canada, the potential for moisture damage in the attic is too great and I should avoid the shower stall light if I can. Apparently the fixture would have to be sealed and would require a 4" dead air space between it and any insulation to prevent fires.

Thoughts? Bad idea?

I don't know where that advice came from----why 4 inches of 'dead air space'?

Look for light fixtures that are 'air tight/insulation contact' IC is the designation.

There is no shortage of IC fixtures.----Mike---
