A process for making mineral wool reinforced polymer composite board . The present invention provides a mineral wool polymer composition and a method of making composite product which consist of core making and laminating a sheet over the core. Mineral wool is reinforced in polymer matrix which acts as binder for developing the core, comprises 10-90 wt% of mineral wool (fibre) in free form or pretreated bonded form. Developed core is laminated by an adhesive to a ply sheet / metal sheet/ laminated sheet/ fibre reinforced polymer sheet to form board, panel / door shutter/ window etc. The polymer used is of thermosetting type.
