A thermal insulation product based on mineral wool, characterized in that the fibers have a micronaire of less than 10 l/min, preferably less than 7 l/min and especially between 3 and 6 l/min, and in that the material has a thermal conductivity of less than 31 mW/m·K, especially less than 30 mW/m·K. The parameters for obtaining this product are in particular the pressure of the burner, the rotation speed of the fiberizing spinner and the daily fiber output per spinner orifice.

Product based on mineral fibers and process for obtaining it

A device for flowing molten glass suitable for installation on a glass melting furnace, including: a flow channel including an outlet of given diameter; and a device for regulating flow of molten glass at an outlet of the flow channel, including: a removable plate including a through-orifice with an area smaller than an area of the outlet of the flow channel; and a movable shuttering mechanism configured to adjustably shutter the outlet of the flow channel or the through-orifice of the removable plate. The device allows a single furnace to be used for various types of glasses having very different viscosities.
