    I have pulled out the bottom refractory panel and three upper ones from a fabricated fireplace unit.
    After studying the design I cant see why I couldnt mortar in new firebrick. I can obtain firebrick 1.25 inch thick which would fit good. Anybody done this before?? Thanks.

    Why would you want to mortar it? It is not necessary. After a while the ash will pack up in the cracks between the bricks and act as mortar anyway.

    I should think one bump with a log and those skinny firebricks would tumble like Humpty Dumpty! Thx

    Suggestion: Post a few pictures of your fabricated fireplace unit.

    The upper and lower channels would provide cooling air circulation between the sheet metal backing and the new 1.25" firebrick. Bottom sheet metal has metal structure underneath.
    The weight would be similar between the old refractory panels and the new firebrick. I would lay the base firebrick first and have the walls rest on the base, same weight as before.All mortared.

    One issue I don't know about....do the old panels and the new firebrick (similar thicknesses) have similar heat transmission properties. Seems like firebrick would reflect heat better but I dont know, or its not a big issue because there are three layers of sheet metal and air spacing before you reach wood framing.

    I see universal refractory panels (cut to fit) for sale on the web but they are only 3/4" thick....that makes me uncomfortable going thinner.

    Thanks so much.
