Norlite Corporation

Norlite Corporation operates two high-temperature rotary kilns that utilize recycled fuels to produce a lightweight aggregate that is used in bridges, buildings, specialized fill, and growing media for green roofs. Norlite is a manufactured lightweight, porous ceramic material produced by expanding and vitrifying select shale in a rotary kiln. The process produces a consistent and predictable high quality ceramic aggregate that is structurally strong, physically stable, durable, environmentally inert, light in weight and highly insulative. It is a non-toxic, absorptive aggregate that is dimensionally stable and will not degrade over time. Norlite offers designers solutions to the challenges of reducing dead loads, lowering thermal conductivity of building products, improving fire ratings, enhancing soils, and treating wastewater, just to name a few.
