Can anyone identify this insulation?
I am working on getting things together to add insulation to my attic in a house we purchased less than a year ago.
After looking online I can't determine what I'm working with when it comes to what is in the attic currently.
Any experienced folks able to identify what is up there? Based on pictures I've seen online it looks like quite a few different things.
Thanks

My first thoughts are of a rock wool type product. It looks fairly old there.
How old is the house ?

I think the key is, it doesn't look like vermiculite. As long as it isn't contaminated with rodent droppings it should be fine to leave in place and cover with new insulation.
Before the new insulation is added, air sealing is a must. It is a big saver and very difficult to accomplish after more insulation is added.
Here's a check list for air sealing: https://www.energystar.gov/ia/partne...ide_062507.pdf
You might also want to set some 2x6's on edge running across the rafters to add plywood for a center walkway and hang markers for electrical boxes and anything else that will be buried.
