Insulating Bricks

Mosconi has developed a full range of insulating bricks that fit to various technologies. They distinguish for their low density and fine porosity, that guarantee excellent insulating properties.

SUPER INSULATING BRICKS

Expanded perlite and selected clays are ceramic bonded by firing the bricks at approximately 900-1000°C. The resulting product is distinguished by very good mechanical properties and stability at increasing temperatures. All variants feature very sharp and strong edges.The bricks are available in a wide range of sizes and formats, as well as different finishes (Trimmed or Machined).

INSULATING FIRE BRICKS

The unique production process, the highest quality kaolins, and careful dosage guarantee a high-quality product with excellent insulating and technical characteristics.
