Kiln Shelf

[Di P]

I have recently bought the Silverline Kiln from Kilncare and am really struggling to find a shelf to fit. At the moment I am using fibre blanket on the kiln floor, but this is proving costly as it marks quite easily. The floor space of the kiln is 100 x 79cm. I thought I would buy a sheet of Ceramic Fibre Board or possibly Calcium Silicate Board but my local builders and plumbers merchants have all drawn a blank. I know I can order this from a kiln linings supplier and a glass supplier but their delivery costs are high and so was hoping to get it locally. I am on the Leicestershire/Nottinghamshire border, does anyone in the UK know of someone in this area who can supply it?
