Abstract
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.

(canceled)
A thermal insulation product comprising mineral wool and having a thermal conductivity of less than 31 mW/(m·K.) and at least 80% of its fibers aligned within plus or minus 30° with respect to the planes formed by the longer dimensions of the thermal insulation product,
- wherein the fibers of the thermal insulation product have a micronaire of less than 10L/min and an average fiber diameter of less than 2 μm, and
- wherein the thermal insulation product is in the form of a single layer panel.
A thermal insulation product comprising mineral wool and a binder and having a thermal conductivity of less than 31 mW/(m·K.) and at least 80% of its fibers aligned within plus or minus 30° with respect to the planes formed by the longer dimensions of the thermal insulation product,
- wherein the fibers of the thermal insulation product have a micronaire of less than 10 L/min and an average fiber diameter of less than 2 μm,
- wherein the thermal insulation product is in the form of a single layer panel, and
- wherein a content of the binder in the thermal insulation product is between 5 and 8 wt %, based on a total weight of the thermal insulation product.
