Roof paper type products had been used in the Kingdom of Poland since 1857. It seems that the technology of producing bituminous coverings was transferred from Germany. In the initial phase three types of roof paper were produced: - asphalt paper on the base of roofing felt (Asphalt Filtz) - tar sandy paper on cardboard base (Stein Pappe) - asphalt paper covered with talc (Talkthur).
