Mineral Wool Roof Sound Absorption

HIPERTEC ROOF SOUND Mineral Wool Roof Sound Absorption

Self-supporting insulation panel 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.

Sound absorption

The HIPERTEC ROOF SOUND panel is particularly suitable for acoustic control, providing exelent sound absorption qualities over wide range frequency spectrum.

Test in echo chambers conducted to ISO 354/84 Standards in 50, 80 and 100 mm. thick panels produced DELTA LA Sound absouption index of between 12 and 19 dB(A), The graph below shows the corve of the absorption coefficients at the various frequencies for the 50 mm. thick panel.

Sound insulation

HIPERTEC WALL SOUND panels have been tested to ISO 717/82 standards and obtained indices of Rw=31.5-33 dB for the 50, 80 and 100 mm thick panels.
