Lighting – How to prevent heat loss over a recessed light

heatinsulationlightingrecessed-lighting

I have a recessed light installed in a sloped ceiling – no attic space over it. On a cold morning when there is frost or snow on the roof and I stand outside the house, I can see a warm spot directly over where the light fixture is. The light has been off all night so I believe this isn't heat from a bulb – just warm air escaping. What are some good options for preventing this heat loss?

I don't know the model of can (I might be able to poke around to find it) so I don't know yet if it's IC-rated. It's 120V (no transformer).

EDIT: I haven't tried to pull the can down but with the bulb out I can see it's a Juno ICT926 which is IC-rated. I see Juno offers two products: the ALG6 (Airloc Gasket) which is a plastic ring and a VB6 (vapor barrier) which seems like it wraps the box. Is one more desirable than the other or more appropriate for this problem?

if its ic rated i recommend roxaul mineral insulation over the fixture. if it is not ic rated or the rating cant be determined i advise replacing it with one that is ic rated and placing insulation over it.
