Hipertec Roof Sound
Table Of Safe Spans
The HIPERTEC ROOF SOUND panel is manufactured in accordance with a system patented by Metecno and consists of a profiled external steel facing, an internal flat, but perforated liner, with an insulation core of orientated fibre high density rockwool, arranged perpendicular to the plane of the panel and positioned in strips, laid longitudinally with off-set joints and transversally compacted, in such a way as to completely fill the void between the two metal facings.
The ribs of the external metal sheet are filled with shaped mineral wool strips.
N.B.: Do NOT use this panel for climatised buildings.
SOUND ABSORPTION
The HIPERTEC ROOF SOUND panel is particularly suitable for acoustic control, providing excellent sound absorption qualities over a wide range frequency spectrum. Tests in echo chambers conducted to ISO 354/85 standards on 50, 80 and 100 mm thick panels produced DELTA LA sound absorption indices of between 12 and 19 dB (A). The graph below shows the curve of the absorption coefficients at the various frequencies for the 50 mm thick panel.
SOUND INSULATION
The HIPERTEC ROOF SOUND panel has been tested to ISO 717/82 standards and obtained indices of RW = 33.5-35 dB for the 50, 80 and 100 mm thick panels.The curves of the absorption coefficients of the 100, 80 and 50 mm thick HIPERTEC ROOF SOUND panels at the various frequencies are shown in the graph below.
