Abstract
Abstract Exterior, water-repellant facing or covering for a roof or a wall. The material is in the form of plates or slabs with overlap or butt joints. The material may include a support web. To eliminate the risk of condensation and to reduce the transmission of heat, the material is formed of mineral wool and a bonding agent. The fibres of the mineral wool lie predominantly within planes which are perpendicular to the external surface of the material.
