Abstract: Loose-fill insulating products may include mineral wool, in particular glass wool or rock wool, in the form of down, nodules, or flakes, which are obtainable by an aeration that allows the mineral wool to be expanded. The mass distribution of the agglomerates may be obtained by screening 2 to 5 g of insulating product using a vibrating sieve shaker with a stack of screens and a maximum amplitude of oscillation of 3 mm set to 1.5 to 2.5 mm, 1.8 to 2.2 mm, or 2 mm, for 5 minutes, satisfies a relationship (% agglomerates 6-13)?(% agglomerates<6)?5%, where (% agglomerates 6-13) is mass percentage of agglomerates passing through 6 mm and 13 mm screens, and (% agglomerates<6) is mass percentage of agglomerates passing through a 6 mm screen.

Abstract: A method for preparing an insulating product based on wool includes an aeration step inside a device, the device including a chamber and at least one structure capable of generating a turbulent gaseous flow, during the aeration step. A stream of carrier gas is introduced into the chamber and a wool in the form of nodules or flakes is subjected to the turbulent flow of this carrier gas with entrainment in one sense in a direction A and in the opposite sense in a direction B that is the opposite to the direction A so that within the chamber there is at least in one plane perpendicular to the direction A in which the wool entrained in the direction A crosses the wool entrained in the direction B.
