To enhance the oven's thermal efficiency and heat retention capabilities, multiple layers of insulation are applied around the dome. These layers typically include fiberglass, perlite, cement insulation, and wire mesh, applied in a specific sequence to maximize effectiveness. The insulation layers serve to minimize heat loss, reduce energy consumption, and maintain consistent cooking temperatures throughout the oven. Each layer is meticulously applied and compacted to ensure uniform coverage and optimal insulation properties. Attention to detail during this step is crucial to achieving superior performance and durability of the outdoor pizza oven.
