[FAQuestions]

What is the advantage of the Komodo's two-layer construction VS the other ceramic grills?

The body’s material is of the utmost importance. Harbison Walker, the industry leader in refractory products and I, designed, engineered and developed both materials and the manufacturing process for Komodo. The final product is a two-layer sandwich of a dense inner layer and a lightweight outer insulating layer.

Thermal mass is the ability of a material to absorb heat energy. A lot of heat energy is required to change the temperature of high density materials like concrete, bricks and tiles. Thermal mass is not a substitute for insulation. Thermal mass stores and re-radiates heat. Insulation stops heat flowing into or out of the object. A high thermal mass material is not generally a good thermal insulator. How my two layer design works. When fuel is burned the dense inner layer comes to temperature (thermal Mass) quickly, it holds heat and reflects heat back towards the food. The lightweight insulating outer layer holds the heat in. The BBQs temperature is easy to stabilize and move both up and down while the insulation makes them extremely fuel efficient. These features make cooking temperatures easier to control.

No other ceramic grill gives you the best of both worlds.. A dense refractory material near the heat source and an insulating jacket to keep the heat in and save fuel.

The thin walled ceramics like BGE attain thermal mass quickly but also loose it quickly due to the lack of mass in the material. Put them where a cold winter wind blows and their temperature can be a bit unstable. Their lack of insulation results in heat loss as well as the outside can become very hot and potentially a burn hazard.

The thick, dense walled Portland-mix BBQs like the South of the Border K might take a while to get there but they do hold thermal mass well because of their large volume of dense material but reducing temperatures also takes a much longer because their volume... Fine if you wanna wait.
