I was inspecting a house here in Southern Calif., the house was build in the late 60’s. In inspecting the attic, the insulation that I found was laid in and is a fiberous white and brown material resembling cotton and wool. I do not believe it is asbestos but I want to make sure. Anyone have experience or can identify this material. Just as an added note, the heating/cooling ducting was covered in the asbestos corrgated material.
