Insulating recessed lights - from below?


Hi - I've got recessed can lights with no access to above (shallow attic crawl space w/vent) - cold air leaks in like crazy. Anybody ever insulate them from below? I use CFLs in them so I'm not worried about overheating. Anybody have any experience with this? Thanks!

You can remove the cans from below.

Remove the trim and you will see 3 screws holding the can to the housing. Remove them and slide the can down.

If they are IC (insulation contact) rated cans you can stuff as much insulation above them as you want. If they are not IC rated you need to keep a few inches clearance.

If you just want to seal the holes in the can, use that thin metal duct tape.

Thanks - I'll give that a shot first - a friend suggested cutting access panels in my ceiling sheetrock, putting fiberglass around the housings, but if I can get around the cans without doing that...

Is the "IC" rating only for when you use incandescent/halogen bulbs? I mean, if you're using CFL's, do you even have to worry about overheating?

When you are doing electrical/construction work, you need to think not only of yourself, but of future owners of your house as well.

It is possible that a future owner would replace the CFL's with regular light bulbs. Best to follow the instructions from the manufacturer of the fixture.

That's an excellent point. I just checked - these are "IC" cans. I think my issue is more with making them airtight than insulating them - when you take a bulb out you can feel the draft coming right through the can.
