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.
