Claim Text:
1. A thermal insulation product comprising mineral wool comprising fibers, wherein the fibers have a micronaire of less than 10 l/min, wherein the product comprises infrared absorbent and/or reflective elements, and the product has a thermal conductivity of less than 30 mW/m.K, wherein at least 75% of the fibers are approximately parallel to the longest dimensions of the product, the thermal insulation product has a density of at most 35 kg/m the approximately parallel fibers are produced by depositing infrared absorbed and/or reflective elements on fibers with an installation comprising an internal centrifugation device that comprises a spinner capable of rotating about an axis X which has its peripheral band drilled with a plurality of orifices for delivering filaments of a molten material, an annular burner which attenuates the filaments into fibers, a receiving belt for receiving the fibers, and a conveyor for the fibers that extends beyond the receiving belt, wherein the speed of the conveyor is greater than the speed of the receiving belt by more than 10%.
