Fiber "felt" sounds like roofing felt, which is pretty thick. But I can't really find a definition of fiber felt. This stuff is probably about twice as thick as the vinyl wallpaper that was on it. Do you know what fiber felt is?
I was just looking up asbestos vinyl wallpaper but can't find any pictures. Does it look as though this material could have been the wallpaper backing? -- Prevent Malware
