Calme, beautiful panel of porous sintered aluminium with superior sound absorption

Calme is a highly engineered material, representing the culmination of many years of development in advanced sintering and fine-grain metal processing. Aluminium grains mixed with pre-alloyed metal powders are formed into rigid panels in a sintering furnace. Sintering allow the particles to fuse together at a temperature below their melting points; the result is a strong, durable panel, that is nevertheless highly porous. It is the great porosity of Calme that gives it the ability to absorb sound.

Stucco

Aluminium particles are heated to just under melting point during the sintering process. This creates open holes that result in a sheet of high porosity of 45%. Thanks to this porosity, the sheet has a superior sound absorbing effect without the use of mineral wool. An air space behind the sheet is all what is needed. The version Smooth is only available in a thickness of 3 mm. The Embossed, Corrugated and Stucco versions can be supplied in a thickness of 2 mm and 3 mm.
