8.11 - Acoustics
From TGN Online
SMD SR roof products can be provided with the webs or flanges partially perforated. When used with a layer of acoustic insulation as part of the site-assembled double skin system this provides sound absorption and reduces reverberation from noise within the internal space.
The structural properties for perforated profiles are lower than that for the standard products.
