EPD document prepared for RBS Ravago Stone Wool Board with Aluminium Foil registration number S-P-04877 has been registered and published in EPD Turkey and The International EPD System. Registered EPD document applies to all global markets.
Stone wool boards with aluminium foil is an insulation material which contains %98 natural fibre and obtained by transforming the minerals and inorganic volcanic stones into natural fibre by melting them at high temperatures. Stone wool boards with aluminium foil coated on one side. It ensures heat, sound and fire insulation in granite, marble, aluminium and glass claddings; and ensures fire insulation at air-conditioning surfaces.
Inputs: The raw materials are measured and sent to a melting furnace. For stone wool these are basalt, cement and limestone.
Furnace: The raw materials are melted in a furnace at very high temperatures, typically between 1300°C to 1500°C. The smoke created during this process is filtered and flue gases are cleaned to minimise any environmental impact.
Spinning: The droplets of melt exiting the furnace are spun into fibres. Droplets fall onto rapidly rotating flywheels or the mixture is drawn through tiny holes in rapidly rotating spinners. This process shapes it into fibres.
Binding: Small quantities of binding agents are added to the fibres. The structure and density of the product will be adapted according to its final usage.
Curing: The mineral wool is then hardened in a curing oven at around 200°C.
Cutting: The mineral wool is cut to the required size and shape, for example into rolls, batts, boards or it can be customised for use with other products. Off-cuts and other mineral wool scraps are recycled back into the production process, which further reduces inputs and energy requirements.
Packaging: Due to its impressive elasticity, mineral wool can be compressed during packaging to reduce its volume.
