Insulated Roof Systems > Hipertec® Roof Sound


Self-supporting panel system, insulated with rockwool for roof and wall applications, requiring a high degree of resistance to fire, combined with sound absorption.
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 high density orientated 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.
Maximum panel lenght: L = 15,500 mm.
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.

TABLE OF SAFE SPANS
Values guaranteed with steel sheets, thickness 0.6 + 0.5 mm. The spans l in metres, as a function of a uniformly distributed load p (daN/m2), have been obtained from tests carried out in Metecno laboratories and calculated to provide a deflection limit: f <= l/200 of the span and a minimum safety coefficient that complies with the UEAtc standards for insulated panels, which have been established and are implemented by primary European Certifying Organizations.
