Attic Insulation - what's best?
I'm sure this has been asked and answered, so please forgive me for asking again, but I've read through some threads and I am still confused.
I'm having my 1930 house re-roofed next week and thought it would be a good time to do the blown in insulation (while some or all of the roof is off). I currently have about 4 inches of something that looks like loose cellulose. Another section of the house has what looks like vermiculite. I had planned to add about 10 more inches of blown in cellulose (I live in Northern Nevada near the Sierras, so we get snow in the winter and summers can reach 100 deg.)
When I called HD this morning to inquire about renting the machine, the guy told me that blown in fiberglass is much better, and that he wasn't even sure whether they still had the machine to do the cellulose. Does this sound right? It caught me by surprised because I thought the cellulose was the way to go. For some reason I'm not too keen on the idea of doing fiberglass. What do you guys think?
