Cast iron might be a better choice
After having to replace my back refractory panel, I read that firebacks not only projected more heat but also protected the back panel. The price for this steel unit was right so I decided to give it a try. At first i was put off by the shiny stainless steel, however; the fire soot soon darkened the surface. The stands work well and there is no danger of the fireback tipping over. The steel is a thick guage and the edges are beveled to reduce the buckling caused by the heat of the fire. Even with the edge bevels, there is a some buckling to the fireback. It is easy to see by the fact that the support stands are no longer parellel. This occurred after the first extended fire. I suppose the general function of the fireback has not been impacted, and the buckling has not gotten worse over a winter of fires, however; I may go with a thicker cast iron fireback. Don't get me wrong, the fireback is sturdy and should last for several years, and, given the price, is better than not having anything. Also it does put out noticeably more heat.
