- Get some Sonotube concrete forms that are 6" larger in diameter than
- your fixtures, cut off sections long enough to extend a few inches
- above the projected level of insulation, and cover one end with
- newspaper. Place one piece over each light fixture, have the insulation
- blown in, then pull off the newspaper. No worries about insulation
- falling onto the fixture, or worrying about the crew "brushing it
- away". It's also fairly cheap. You could also use single wall stovepipe,
- or even a piece of sheet metal bent in a circle. Just be sure to
- pull the newspaper afterwards....

- With blown-in insulation, it's also a good idea to make sure it's
- applied evenly. Someone I worked with had his house done, and
- there was a nice 24" thick layer of insulation--around the access
- hatch. The rest of the attic had 10" or so; TVA (the local power
- provider, who was financing this) made the company come back.
