Classification: CPC D  C | IPC C  D

Claim 0:
1. A loose-fill insulating product, comprising:
rock wool in the form of down, nodules, or flakes,
wherein a mass distribution of the agglomerates obtained by screening 2 to 5 g of insulating product using a vibrating sieve shaker comprising a stack of screens and a maximum amplitude of oscillation of 3 mm set to between 1.5 and 2.5 mm for 5 minutes, satisfies a relationship

(% agglomerates 6-13)−(% agglomerates<6)≥5%,

wherein (% agglomerates 6-13) is a mass percentage of agglomerates that pass through screens of both 6 mm and 13 mm, and (% agglomerates <6) is the mass percentage of agglomerates passing through a 6 mm screen, and
wherein the mass percentage of agglomerates passing through the 6 mm screen is greater than 10%.
