What is a speed oven and how is it housed in cabinetry?

A speed oven combines convection heat and microwave energy to cook 2–8× faster than a conventional oven. It generates more radiant exterior heat than a standard microwave. The surrounding cabinet carcass requires heat-deflection tape on adjacent gables and a minimum 1/4" reveal gap around the appliance face. Speed ovens are commonly stacked in a tall column: warming drawer at the base, speed oven at mid-height, and a full-size wall oven above.
