I'm going to add insulation to my attic. The home was built in 1967 and
the current insulation is pretty thin. Should I add fiberglass pads or
blow it in using cellulose? It's about 900 square feet to cover.

Thanks!

I would vote for the cellulose, we blew a dozen bags into the attic of
our in-laws house that is about the size you are talking about,
it seemed to help quite a bit.

I am thinking of doing some to our attic as well, just try and do it
when it's cold out and not baking hot in the attic.

Cellulose is quicker, but way messier. Fiberglass can be removed and replaced if you
need to do work in the attic. My attic had some cellulose. I covered it with thick fiberglass.

I'm a fan of cellulose. As long as you do the proper prep-work (put
vent baffles in for eave-vents, pre-mark your desired insulation depth
on the trusses/rafters, use plenty of plastic sheeting to isolate the
rest of the house from your work to keep the dust out, etc.), it's not
difficult for a DIY'er with a helper. The helper has to be JUST smart
enough to be trusted to keep their fingers out of the blower (a tiny
bit smarter would help, but isn't 100% necessary).

Call some insulation contractor before shopping. I had R-30 installed for
less than it would have cost me to buy the material at the box stores.

August's electric bill for a/c was half of July.

One cautionary note on the cellulose. It compresses over time and with that
it loses some of its R-factor. When I bought my 1970's vintage home in 1984
they had recently had an additional 6" blown in on top of the batts. That
has steadily reduce to about 4" over the years. I can't tell if the loss of
R has had much effect since I have long since changed over to a heat pump.
Just an FYI to factor in. If you don't plan to stay 20 yrs it's not your
problem and the next guy probably won't think of it.

Also helps work on a day when it's not raining. The folks at the store
really get miserable when you bring their machine back dripping wet. And the
cellulose sucks up water, and gets lumpy.
