Dome Thickness

A cast refractory oven dome for a residential wood oven is typically 2″ thick, which is sufficiently massive to hold heat for baking lots of pizzas in successful, or for holding heat for as long as two-three days for lower temperature roasting and baking, including bread. A modern stainless steel pizza oven dome is typically a fraction of an inch thick, which mainly reflects the heat of the fire or gas burner onto the pizza, and does not hold any significant heat for baking or roasting, without a fire or lit gas burner.

A brick dome oven is 4.5″, the thickness of the half standard fire brick (4.5″ x 4.5″ x 2.5″) provided by Stellar Ovens set on its 2.5″ side. A brick dome holds more heat and has longer lasting pizza baking capacity, though it can take over two hours to heat up, compared with only 30 minutes for a thinner, 2″ cast oven.

A brick vault pizza oven is typically 2.5″, the thickness of a standard fire brick (9″ x 4.5″ x 2.5″) set on its 4.5″ side (and the 2.5″ side facing into the oven). This is a good thickness for a residential wood oven.

A brick vault wood oven is typically 4.5″, the thickness of a standard fire brick (9″ x 4.5″ x 2.5″) set on its 2.5″ side (and the 4.5″ side facing into the oven). For even more thermal mass, some builder encase the 4.5″ barrel vault bricks in an additional layer of standard or refractory concrete.
