Insulating product comprising loose-fill mineral wool

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.
