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.
Norlite is proud to have been serving the block making industry for over 50 years. Rotary kiln lightweight concrete masonry units are providing many economic benefits for the modern block producing industry. These low density load bearing and non-load bearing units conserve costly energy which is a prime concern to architects and owners. Since thermal resistance varies inversely with the density, lightweight concrete masonry units have substantially better thermal insulation properties than normal weight concrete block as the U factor tables verify.
Asphalt produced with Norlite Lightweight Aggregate offers superior skid-resistance while extending roadway life. Norlite decorative stone provides a rustic beauty previously only available in organic materials, but will not fade, deteriorate or rot like organic mulches. Norlite has many advantages as a refractory material, including: high thermal insulation, high structural strength, light weight, low expansion and contraction, fuel savings, reduced maintenance and installation cost. Shotcrete is pneumatically applied portland cement mortar made with an intimate mixture of Norlite and either portland cement or Lumnite cement.
