Guide for selection of refractory insulation bricks
1) Super-Duty Firebricks. Super-duty firebricks are used for thermal insulation in higher temperatures. Many super-duty firebricks are made from a very durable and heat resistant material such as silica. Various kinds of super-duty are used in industrial settings such as the glass and steel industry. 2) High-Alumina Firebrick.
