You can use drywall or plywood or OSB or foil faced insulation or sheet metal or aluminum coil stock to enclose the lighting fixture. Caulk any openings in the electrical junction box to seal wires and reduce by-pass.
Maintain a distance of 2 inches between the lighting fixture and enclosure.
Caulk the joints and caulk to attic deck before insulating.
You can get pre-made enclosures at www. jrproductsinc.com
Have I answered your question?
Thanks you for your outstanding answer. Those enclosures were just what I was looking for! What a great web site!
Best of luck on your project.
Here's to lower heating and cooling bills for your Sister.
I haven't started yet, but thanks for asking. I'm planning the first day of work, which is to remove the leftover blinds, window frames, and empty boxes left in the attic. After that I was going to fluff up the existing insulation, as it's gotten very packed. Finally, I want to put roof chutes or airways under the roof near the soffits at the end of the attic so that I keep the ventilation going up the roof and not have it blocked by the insulation.
Then I'll blow it in!
Your advice was great; thanks!
Hello again David.
You've got a good plan of attack.
Hope all goes well.
