Mineral Wool Sound Absorption

HIPERTEC SOUND Mineral Wool Sound Absorption

Self-Supporting panel insulation meterial insulated with Rockwool for wall and partition application, regering a high degree of resistall to fire, combined with sound absorption.

The HEPERTEC WALL SOUND panel, is manufactured in accordance with a system patented by Metecno, and consists of a micro-ribbed 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 transversely compacted, in such a way as to completely fill the void between the two metal facings.

Sound Absorption

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

Test in echo chambers conducted to ISO 354/84 standards on 50, 80 and 100 mm. thick panels produced DELTALA SOUND absorption indices of between 12 and 19 dB(A).

The graph below shows the curve of the absorption coefficient at the various frequency for the 100 mm. thick panels;

Sound Insulation

HIPERTEC WALL SOUND panels have been tested to ISO 717/82 standards and obtained indices of RW = 31.5 – 33.0 dB for the 50, 80 and 100 mm. thick panels.
