The American Made Grills Insulated Grill Liner (GL-ATSSB2) is a double-lined 304 stainless steel insulating jacket required for installing the Atlas Double Side Burner into an outdoor kitchen island constructed from wood framing, composite materials, or other combustible surfaces. Local building codes require a non-combustible barrier between gas appliances and combustible island materials — this liner creates that barrier with 1" of double-wall insulation, blocking heat transfer from the appliance to the surrounding structure. Purpose-built and precision-sized for a seamless fit with the Atlas Double Side Burner (ATSSB2).
