If you cannot find the right replacement firebrick for your needs in our Fire Brick Catalogue, we can cut one to your specifications.
See below for our guide on how to make sure you get the right vermiculite fire brick for your needs and scroll to the end to see our video on how to use the calculator and how to make your template.

Before You Start

Before you start you want to make sure you have all the measurements necessary to fill in the calculator.

The best way to do this is to remove the bricks from the stove as this will give the most accurate measurement.

If the brick/s are broken piece them back together as best you can to get your measurements.

Basic Rectangular Shapes

For basic squares and rectangles we will need 3 measurements:

  • Thickness
  • Height
  • Width

Shaped Fire Bricks (i.e. Chamfers and Cut-Outs)

For shaped bricks, you will be required to provide a template. It is important you provide as much information around the template as possible so we can cut your brick accurately.
