I am gutting an old sleeping porch on the second level of my 1909 home and was wondering if I have anything to be concerned about with the celling tiles and wall insulation. I have attached pictures of both to this post. THe celling tiles seem to be a pressed fiber board and the insulation on the walls seem to be similar installation as traditional fiberglass but the material is more like cotton??? Anyway, I am hoping I have nothing to worry about but since there is a chance of being asbestos in old homes I wanted to see what you all have to say on the subject. Please let me know.
