Around here mostly on gable ends
of attics, and unheated garages.

came out in the early 1900's, its just called fiber board. you can put siding directly over it. however, you cannot use vinyl cedar shakes directly over it since it needs to be center nailed. need to throw on some OSB for that.

Asphalt board is still available here.
