Insulation around those Recessed Cans

Found a great article at another site about insulating around those recessed cans and thought this would be another great place to post.

The cans seep a lot of air to and from the attic, some studies showing as much as $10 per year per can. Having 12 recessed cans in Central Florida, I'm doing it.

    once done do not ever go to a standard incandescent even temporarily as the heat would build up fast and create a hazard even if you went to a lower wattage bulb.

    They also have cans rated for direct insulation contact which are basically air tight, don't they - why not use those instead of the box around the can?

    I guess if the cans are already in the ceiling, that's a good retrofit - otherwise why not use the proper can from the start?

    Have existing cans, that's why. Should have explained that.

    Yeah, looks like a pretty easy way to seal up those cans. And the insulation board is pretty inexpensive. I would think that foil backed board might hold up to the heat better.

    The bigger you can make the box, the better.
