Acoustic value of the Aluthermo Optima confirmed
Aluthermo Optima® is a high performance insulation system with a reduced thickness composed of two layers of pure 30 microns thick aluminium, polished and treated against oxidation, separated by two layers of air bubbles placed in a honeycomb structure and enclosed in self-extinguishing polyethylene film. The core of the product is a fully stable, hydrophobic and self-extinguishing polyester fiber with high sound barrier characteristics. Aluthermo Optima® efficiently acts on all modes of heat and noise transfer.
Precisely these high sound barrier characteristics have now been confirmed by the Frauenhofer Institut in Stuttgart. Aluthermo Optima® achieves an acoustical insulation of Rw = 41 dB according ISO 10140-2.
