Exclamation IC Hi-Hats and attic insulation....

Just installed hi-hats recently in my attic. I used IC cans, understanding that these can be used with insulation - but, what are the rules with this? The guys at the big 'orange' give me confilicting answers. Is it a three inch space from the can and nothing above, can I insulate over the cans? I have not hooked up the power yet.

Thanks!
Gary

The conflicting opinions is coming from type IC, And type Non-IC.

If the can is Type IC then you can insulate around, and on top, If it is Non-IC then 3" have to be maintained.

Question IC cans and insulation continued...

This means that I can butt up the insulation to and over the can, or just over the can?

Fellow frustrated novice here. IC can lights can be insulated up to and over them. Remember to use unfaced fiberglass insulation when doing so. I believe the paper on kraft faced batts is extremely flammable. I installed IC cans in my daughters room when I redid it. I used unfaced fiberglass up to and around these lamps. I did not opt to insulate over them just in case. Most can light have a thermal breaker in them that will discontinue lamp operation if it becomes to hot.

"To and Over" the can is ok.

Something I want to point out is "some" not all of these great hardware stores we have can miss-lead you to believe that you have bought an IC can.

The noticeable difference you will see is in the "can" itself. Not only a “Tag” will identify the can but,
An "IC can” will not have vented holes in the can itself. "Sometimes nothing bigger then a few ¼” holes". Type Non-IC "cans" do have vent holes, and this is how more heat gets to the insulation in the attic or anything surrounding the can.

Post FYI

FYI-- The IC stands for in-contact,meaning that it is OK for the insulation to be in direct contact with the cans.
