I installed a flagstone patio a few years ago, and have a store bought copper/steel fireplace that my whole family enjoys on cool evenings. Last year I built a drystacked stone wall behind it for aesthetics and a wind break, which worked out well on both counts. The fireplace has seen it's useful life an is time for replacement. This is my plan. I've designed a fireplace with a chimney in the rear, and my pizza oven (barrel type) on top. Some of the details are as follows. The foundation of the fireplace is 12" tall and 36" square. I will build the exterior out of brick that matches my house. The interior will be with standard solid red contractor brick. The rear will angle toward the front, and stop short of the top to create a smoke chamber in the rear, with the chimney installed above the smoke chamber. I don't want to pour cement (right now) so my thoughts are to make the top (top of the fireplace, floor of the pizza oven) out of my existing brick. Between the brick top and low duty firebrick oven floor, I plan on installing a layer of FB Board. Then the barrel type oven. From my design the cooking floor is going to end up approx 30 w by 26 d. After the barrel is complete, I plan on laying my house brick around the perimeter to completely conceal the barrel and install some sort of roof. From what I've read here and on other places, the insulation is one of the most important items for the oven to work efficiently. There have been some q's about using fiberglass insulation above the Insulating blanket. Has anyone considered using cellulose insulation? It's insulating properties are much better than fiberglass, and it can be dense packed, and is more fire resistant. Best of all it's about $5 or $6 a bag at the home centers. My thoughts right now are to fill the open area above dome with cellulose and then install my roof.
I don't have any forum friendly designs to post. Is there a huge design flaw in building my oven on top of a fireplace. They may be used at the same time, but I don't see that happening too often. I also wanted to alert you all to the cellulose insulation, if it hasn't already been discussed. Any and all comments and thoughts would be appreciated!
