Super Insulating Bricks

Mosconi has developed a full range of insulating bricks that fit to various technologies. All qualities are based on expanded perlite, and are distinguished for their low density that guarantees excellent insulating properties.

Expanded perlite and selected clays are ceramic bonded by firing the bricks at about 900°C-1000°C. The resulting product distinguishes itself by very good mechanical characteristics and stability at rising temperatures.
All qualities exhibit very sharp and strong edges.

The bricks are available in a wide range of sizes and formats, as well as different finishing.
