Wound up having to pay a visit to someone across the street from the stove shop, so I dragged Mrs. Blue shopping. Stove guy tried very hard to sell us a prefab fireplace he had on the floor. Mrs. Blue explained that I spend quite enough time messing with the stove I have and that she was in no mood for more wood burning hardware. Then her eye fell on various fireplace door assemblies that admittedly would look better in our living room (Brand was Stoll, I think.) Conversation then turned to the fact that we'd really rather be rid of our monstrous brick hearth (pictured) and that we are considering cladding over it with drywall, similar to some display hearths they had on the floor. Anyhow, he insisted that we could face over the hearth brick by: 1) Removing the pictured heat exchanger grate 2) Stuffing the opening with Roxul 3) Having a mason brick up the opening 4) Screw furring strips to the brick 5) Attach cement board or drywall to furring strips and paint I know I've asked this here before, and the consensus seemed to be, "Don't do that." Is this fellow wrong?
