Arch board

[Tom_saw]

I'm building an arch and would like insulate it with arch board . I would like to find it local ,( Cincinnati , Ohio) if possible. Is there another name for it outside of the maple syrup world ? I'm just trying to keep down on the shipping . Thanks Tom

Tom, I found mine at a furnace refractory company, Don't know exactly what they call it but it was half the price of what my sugar supply place wanted. I had to buy a whole box but well worth it!

I bought some rockwool insulation today from a commercial / industrial insulator . 48 square feet for $16.51.
