Partition wall

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 having a first and a second side and comprising:

• a plurality of column assemblies substantially vertically mounted in a horizontally oriented base profile, each column assembly comprising:
• a central element composed of mineral wool fibres and at least a first spacer elements composed of mineral wool fibres and extending from said central element 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 a side of the central element facing the second side of the wall,
• a second spacer elements composed of mineral wool fibres and extending towards the second side of the partition wall;
• and wherein a density of the mineral wool in the central element is higher than a density of the mineral wool in the first and second spacer elements,
• one or more insulation sections fitted between two adjacent column assemblies of the plurality of column assemblies, wherein each insulation section comprises:
• an inner mineral wool fibre panel provided in a close fit between the central elements of said adjacent column assemblies;
• first and second mineral wool fibre panels provided in a close fit between the first and second spacer elements, respectively, of said adjacent column assemblies, wherein densities of said first and second mineral wool fibre panels are substantially the same and wherein the densities of said first and second mineral wool fibre panels are lower than a density of the inner mineral wool panel;
• and
• a first external wall cover abutting the first mineral wool fibre panel and secured to the first spacer elements of the adjacent column assemblies, and a second external wall cover abutting the second mineral wool fibre panel and secured to the second spacer elements of the adjacent column assemblies;
• wherein at least one of the first and second spacer elements in the column assembly has a fibre orientation which is substantially parallel with a main fibre orientation of the first and second mineral wool panels.
