Hey everyone been awhile since I have been around. I am curious to find out what kind of insulation I have in my attic I haven’t seen this kind yet.
The insulation looks yellowish brown maybe even alittle orange, it seems to be settled in or packed fairly tight, any ideas?

OK - I'll play -
rock wool -
but you really need to give some more info - or even a picture -
What other info could I give but maybe a pic? You say it is rock wool insulation, I had never heard that name before, what is the R value at about 3 1/2" to 4" thick ? or is it a very good insulation?Scott Beckett's Handyman Service

Rock Wool insulation has an R-value of about 22.5 for a 6" stud wall cavity, which is at least 10% more than spun glass insulation. It is made largely from mining waste ( meaning the basalt and/ or other rock that didn't have ore in it and is put to one side.)It is much better than fiberglass insulation since it doesn't colect dust and enable mold growth. It also won't sag in the cavities if it does get wet, which fiberglass is prone to do.
It's stiff, densely packed stuff and when you fill the cavity the batts stay put. Makes working with it much easier.
If it does get wet, (roof leak, floods, etc.,...) it doesn't collapse in on itself, and it is rare for mold, etc., to grow on it.
Bonus: it doesn't itch. It is highly resistant to open flames: Roxul's trade show exhibits have a batt set up and a propane tiger torch is aimed at it and lit. They leave it running for hours, if the exhibit hall isn't too hot already. You can barely feel any heat on the opposite side from the flame.
Even after 4 hours.
Really. No, I don't work for them, but I do make a point of recommending rock wool over most other type of insulation...well, except for straw bales and blown-in cellulose.Roxul's rock wool is a slightly yellowish greyish colour.

Well you gave a color and nothing else.Is hard or soft? Beads, strands, sponging??

A-holes. Hey every group has to have one. And I have been elected to be the one. I should make that my tagline.
what Bill said - I gave you a WAG (but honest guess) based on almost no information - I guarantee that this board can identify your product, but we've got to have more to go on - "there's enough for everyone"
Okay, it is powdery type of stuff but it is packed in the cavitiy fairly well. So it does sound like rock wool insulation from what had been discribed earlier. Well thanks for the info everyone.

How old do you think it might be? You said "powdery"... As far as I know rock woll is at least somewhat fiberous. That doesn't sound like rock wool. Pick up a hand full of it and take a fairly close up pic. Post it here.
Sorry it took so long to reply to you but I got up in my attic to take the pic today for you. I took a good look at this stuff and I am starting to think that it might be very well aged blown in insulation ( cellulose ) but texture and color is throwing me off.

I say it's cellulose too.
It oftentimes turns brownish when it gets old.

photo looks like cellulose to me

Looks like cellulose (finely shredded newspaper) to me. Should be fairly soft and cottony, save for possibly a "crust" where it's gotten damp.But all sorts of ground-up stuff has been used over the years, so could be something else.

sounds like dehydrated rat poop so far. Can I buy another clue?
