Non poisonous, asbestos free, organic fibrous material. BITUWELL HART-S PLUS sheets are completely impregnated with non harmful, trade-marked bitumen, with a colour impregnation that firmly adheres to the base material, thus ensuring a long standing colour stability.

This is a normal process that rapidly stabilises.
