Asbestos wrap ?
Thank You for the very good pictures.
Yes this duct wrap contains asbestos. The dead giveaway to me is the small corrugation pattern in the sheet. The white fibrous stuff is asbestos, the gray is mostly simple airborne dirt that has collected around it.
If you decide to deal with it, wet it with glycol and water 1-3 parts mixed, and make sure you pressurize your house so dust is forced out of any openings, not into your house and do it on a calm day. A HEPA Mask is obviously needed, and paper throwaway coveralls, with hood and booties.
Double bag and hepa vac after removal. You can buy a hepa filter for most shop vacs.
Use your head, take your time, and think the whole process all the way through to clean up and disposal.
