Aluthermo Optima® is a high performance insulation system with a reduced thickness that efficiently acts on all modes of heat and noise transfer. Aluthermo Optima® is 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 selfextinguishing polyethylene film. The core of the product is a fully stable, hydrophobic and self-extinguishing polyester fibre with high sound barrier characteristics.
