The hybrid-core version of the acoustic roof panel combines a perforated inner sheet with a rock wool based hybrid core. The polyurethane strip along the edges holds the screw seating firmly and makes the panel somewhat lighter; the fire class remains A2-s1-d0.
The perforated surface lets sound reach the core, and the porous core absorbs it. The panel is used for room acoustics, not for sound insulation.
Thermal conductivity is 0.045 W/mK, with thicknesses up to 200 mm. The profile has five ribs, and the span is selected from the load table together with the snow load; the tables are in the Library section.
