I just moved into a 30 year old house and am puzzled by something I saw in
the attic. At first I thought they were bundles of unused insulation. But
then I realized they were boxes (about 2' cubed) that were fixed on the
attic floor. They are wrapped in insualtion material, and I believe they
are all immediately above recessed light pots in the top floor ceiling
below. I've never seen this before. If they are just there to insulate the
pot lights, then it seems like overkill!
There is also ducting up there that feeds the top floor vents, and they are
insulated in the usual way, with rolled insulation material covering them.
The boxes appear not to be related to the ducting.
Anyone seen boxes used like this before?
