High Alumina Refractory Bricks / Insulation Firebrick SK34 SK36 SK38 SK40



Laurel produces a comprehensive range of Fire clay brick consisting of 30-55% Alumina all of which exhibit excellent strength. For more arduous environments we offer a hand fired "super duty" Fire clay brick with a very high mechanical strength.

Typically our firebrick range is based upon flint clay giving it both a low iron and low alkali characteristic. Resistance to thermal shock, abrasion, chemical attack and reducing atmospheres are just some of the key criteria determining choice of product within each application. a wide range of sizes are held in stock.
