Mineral fibre-based insulating panel, production method thereof and use of same

摘要

The invention relates to an insulating panel which is used as lagging for an electrical apparatus and which is based on mineral fibres, particularly glass fibres. The invention also relates to a method of producing one such panel. The inventive panel comprises a core ( 13; 113 ) of interconnected mineral fibres and a coating layer ( 9, 9 ') which is applied to at least one face of the mineral fibre core ( 13; 113 ). The coating layer ( 9; 9 ') comprises a non-woven fabric, a glass fabric or a glass mat and is connected to the mineral fibre core using a mineral chemical binder or a mechanical connection.
