Insulation Bricks, Material : Alumina

We offer an extensive range of insulating firebricks. Our lightweight, precision-made insulating bricks help our customers to reduce their operating costs by saving energy.

Most of our insulating firebricks are made from high-purity refractory clays with granulated additions of alumina for the higher temperature-rated products. They are suitable for applications at service temperatures ranging from 1250º c to 1850º c. They can be directly exposed to flame, and combustion.

• Very high refractoriness, structural strength
• Excellent strength at ambient and elevated temperatures
• High resistance to reducing atmosphere
• Outstanding insulating values across the temperature range
• Lower heat storage than denser refractories
• Very low levels of iron and other impurities
• Low thermal conductivity, shrinkage and creep Insulation Mortars

We recommend insulation mortars based on the type of brick being used. We have a selection of Calcined Clay and Bauxite mortars to be used along with our bricks for a good bonding and high thermal performance.
