Standing Seam Systems

For built up metal roofing system applications (e.g. standing seam), Rockwool Acoustic Membrane should be applied between the metal outer sheet and insulation.

For enhanced performance, the membrane should also be positioned between the insulation layers.

A typical construction;

. Aluminium outer sheet
. Rockwool Acoustic Membrane 5 (5kg/m2) – 1 layer
. Rockwool Cladding Roll
. Rockwool Acoustic Membrane 5 (5kg/m2) – 2 layers
. Rockwool RW3 Slab
. Vapour Control Layer
. Steel liner tray

In the absence of test data, Rockwool Limited have assessed that similar constructions with combinations of Rockwool Acoustic Membrane and Rockwool insulation materials are likely to achieve Weighted Sound Reduction Index values of up to 50 dB.
