ROOFING FELTS
- Description: Roofing felt is a crude paperboard impregnated with bituminous impregnating agents (tar, asphaltic bitumen); it is produced in web form and supplied in rolls. Both sides are covered with mineral materials (e.g. sand) in order to help prevent the coating from running off when exposed to heat or from sticking together in the rolls and to provide protection from atmospheric conditions. A distinction is drawn between tarred board and bitumen board.
