In my particular house I have that white wool insulation in the attic. It's
not blow in insulation, but a definite wool compound. Anyway given a
choice, is this type of insulation effective, does it have any problems that
I might encounter - like bugs or rodents? I don't live in the Arctic
Circle, but I'd rather minimize heat loss in the winter and heat gain in the
summer if I can.
I would be more concerned whether or not you have enough, standards and
codes were make before energy costs were a major burden. Figure what you
have at R 3.5" and look into what is optimal for your area. You can
usualy take your code rating and double it and have a great benefit
It would be helpful if you could 'ReFluff' the insulation and then
cover it with blown in for a total depth of 10 inches.
The same instrument that you use to blow in the insulation will
'Fluff' the wool insulation you have. Or just leave it be.
Rodents love the wool insulation to burrow through, but so what.
Just keep rat poison out.
I've purchased insulation that was all white, and that wasn't long
ago. Can you give an age of the house?
As for heating/cooling, I added like R30 over my attic existing
insulation, and saw drops in both heating and cooling. I make my
friends jealious. ;)
