Learn how to identify and air seal leaks around an attic can light/recessed light. Can lights or recessed lights in your attic floor are notorious for air leaks allowing conditioned air into your attic and making your home less energy efficient. Properly insulating can lights can save money, save energy, make your home more comfortable, and reduce the emissions that contribute to climate change. It’s easy to do yourself.

Here are the steps to seal air leaks around recessed lights in your attic:
1. Turn off the light associated with the fixture you are sealing
2. Carefully enter your attic (for safety you may want to lay a piece of plywood across the floor joists to stand or kneel on) and find the recessed light or ‘can.’
3. Pull existing insulation away from the base of the can (be careful as the can may still be hot).
4. Place your insulation cap over the can to make sure it fits properly.
5. If necessary, remove the cap and make modifications to it so that the bottom rim lies completely flat against the attic floor when placed over the can (you may need to mark the cap’s base with a pen to indicate places where the cap needs to be cut to fit over any supporting brackets.
6. If necessary, cut the areas on the cap you’ve marked.
7. Once the insulation cap is placed over the can and lies flush against the attic floor, apply spray foam around the base of the cap and let it dry and cure for at least 30 minutes.
8. Once the foam is dried, cover the cap with the existing insulation.
9. You’re done with this step! Now there are a couple of other things you can do to improve your home’s energy efficiency:
