Thermo glass or mica

I need a piece of glass or mica sheet to withstand high tempertures. I found a place that would charge me $58.00 for a piece of thermo glass 4x13 in. A piece of flexiblle mica would be good too. Is it cheaper and where do they sell it?
Thank you

Boiler door. Not sure. High enough to crack regular glass.
