IC vs. non-IC

I purchased and installed a non-IC recess light fixture in a room that has insulation in the ceiling. I didnít think to check if it was IC or not.

Do I need to reinstall the fixture with an IC one?

Could I build a wood box to separate the fixture from the insulation?

Any other options?

Non-IC cans need to have a 3" gap from the insulation.

If I were you I would replace the cans with IC rated ones to avoid all the energy loss. You will continue to pay extra due to the hole in the ceiling letting conditioned air escape.

If I built a wooden box to cover the fixture and put the insulation over it, wouldn't that insulate everything?

Yes. A better option is to build boxes using 1 1/2"-2" polystyrene rigid foam. (many times it is pink or blue) Caulk and tape all seams including where it meets the framing and drywall. Just keep everything 3" away.
