The partition wall has a plurality of column assemblies, such as at least two, substantially vertically mounted in a generally horizontally oriented base profile.

Abstract: The present invention concerns a partition wall for a building structure comprising a plurality of building units separated by such partition wall to provide acoustic insulation therebetween, said partition wall comprising: a plurality of column assemblies, such as at least two, substantially vertically mounted in a generally horizontally oriented base profile, each column assembly comprising a central element made of mineral wool fibres and at least a first spacer elements made of mineral wool fibres and extending from said central section towards the first side with a first intermediate profile provided between the central element and the first spacer elements and a second intermediate profile provided on the side of the central element facing the second side of the wall, a second spacer elements made of mineral wool fibres and extending towards the second side of the partition wall; and wherein the density of the mineral wool in the central element is higher than the density of the first and second spacer
