Hi All,
After working hard to get my hearth slab flat, I find that some of my insulation boards are a bit warped, or curved...essentially not flat. My plan was to lay down the boards on my slab, put on a layer of firebrick, and install the oven on top. Not having that insulation base flat tends to complicate matters.
Has anyone ever tried to flatten out a ceramic fiber board, perhaps by weighing it down on a flat surface (like my slab), or should I return the boards and get a replacement?
To give you an idea, if I lay the worst board on my slab, I get a 1/2" gap between the slab and board.
Thank you all for any advice you can provide.
