I want to replace them with these LED ones that home depot sells: I took a look at the insulation around the recessed light cans from the attic, and there is none. Improve this question. LEDs can still generate some heat, it really depends on whether the can is IC-rated or not.
Your idea is reasonable and reasonably safe. The problem is that someday down the road someone may swap back to old-school flood bulbs, and that could be dangerous.
Ah yeah good points - ok so probably best to just replace the cans, looks like they make air-tight ones anyway, I don't think I could get air-tight by just doing the insulation myself: homedepot. Airtight is not the issue, it's being listed to be covered by insulation and still be able to shed heat from the bulb, however their design can do that and still get listed. All fixtures must be built for the worst case of incandescent bulbs, unless it is impossible-by-design to put one in there.
Your LED light trim is effectively sealing your living space from your attic. I wouldn't sweat it. Add a comment. Active Oldest Votes.

Much of these outgoings are made up of energy bills , especially during the cold Winter months. Covering surfaces with insulating material, though, can be very effective at helping to keep your energy costs down. This will usually help to pay for the investment many times over, while also helping to make your premises a more comfortable place.
While insulating surfaces can be effective, however, it is important that the building is effectively sealed from heat loss. But can you insulate over recessed lights and other similar features to obtain this fitted seal? Just one small area that is not insulated will allow for heat to escape, decreasing the effectiveness of your installation considerably.
Awkward fixtures and fittings, like recessed lights, are difficult to cover, and may cause issues with your efforts. Recessed lights are generally found in ceilings, and the fittings are generally accessed from above through the floorboards or attic space.
Recessed lights are installed into holes that have been created in the ceiling and, without proper insulation , this provides an opportunity for a lot of heat to escape. This is not normally a problem in itself, because heat loss can usually be prevented with an effective insulating material. The question of can you insulate over recessed lights , however, tends to be more centred around concerns over safety. Light fittings emit heat. With standard lights, this is not a problem when insulation is concerned because the heat emitted will be retained within the room.
At the most, it will help to make the room a little warmer , which is a good thing in the winter. For recessed lights, however, much of the heat that is generated is radiated from the fittings above the ceiling. The small insulation particles are predominantly made using recycled paper with a fire retardant.
Rather, keep that insulation in the attic and other areas away from recessed cans and use a different, less flammable option around recessed lighting fixtures. Rock wool also called mineral slag or mineral wool is the safest, least-flammable insulation option around recessed cans. As you can imagine, this insulation type is regarded as the least flammable and most fire-resistant insulation option available. It rivals that of asbestos insulation no longer legal in the U.
Rock wool is more expensive than other eco-friendly alternatives , so budget-conscious homeowners could opt to select a cheaper alternative for the attic, exterior walls, and crawl spaces, only using rock wool to surround the recessed cans. The next best option s are fiberglass batts or sheets, without the paper backing. Fiberglass batts and rolls are still considered the American standard for safe, affordable insulation although you should always cover up and wear gloves, a mask and safety goggles when handling it to avoid inhalation, penetration, or ingestion of fiberglass particles.
Your lighting solutions are as important as your insulation choices. Work with a licensed, qualified electrician when selecting new lighting fixtures for your home or workplace and before installing the insulation. Lighting fixtures have different rating tiers, based on their interaction with insulation. The letters "IC" are verification that the fixture is rated for insulation contact. You may also see the words "Air Tight. Cover the holes on the sides of the canister by stuffing loose fill or batt insulation between the canister and the ceiling joists if it isn't an airtight fixture.
The holes allow you to adjust the bulb height, but they also allow air to pass. Seal the holes with caulk if the model is airtight.
