Fire clay bricks/ Firebick is kind of high temperature materials which used in lining furnaces, kilns, fireboxes, and fireplaces.

Laurel produce a comprehensive range of fire clay brick consisting of 30-65% 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.
