How to Make / Mix Perlite or Vermiculite with Cement for Pizza Oven Insulation

Insulation Is Important in the Oven

Insulation is crucial in the walls of your home. It keeps your home warm in the cold winter months and cool in the hot summer months. When you are baking in the LOWER OVEN, the insulation that is in the cinderblock helps retain the heat that was created when you fired the oven.

The insulation mix keeps the heat in the hearth firebrick. If you didn't have the insulation mix in the hearth slab, the slab would absorb the heat from the hearth firebrick like a sponge absorbs water. This heat absorption would prevent the hearth firebrick from reaching their maximum heat retaining potential. And super-hot hearth firebrick not only radiate intense heat for hours (which is really helpful when BBQ), but you will actually use less firewood compared to metal lined wood-fired BBQ.

The insulation mix in the UPPER OVEN (between the 2 rows of firebrick and the concrete panels) help retain the intense heat that is made during the pig roasting process – and retains the heat that is created during the smoking process (when the fire is made in the lower oven). As the smoke rises out of the smoker opening (which is the 13½” x 2½” hole in your hearth slab), the heat from the fire and smoke is retained in the upper oven firebrick which aids in the smoking / cooking process. If you didn’t have insulation between the 2 rows of firebrick and the concrete panels, the outside temperatures would cool the firebrick and your oven would be much less efficient.

VERMICULITE                                                                                                       PERLITE

Perlite and vermiculite are natural soil additives that help improve soil structure in similar ways, here is the Characteristics of Perlite vs. Vermiculite 

Differences Between Vermiculite & Perlite 

Vermiculite will mix with soil and help to retain water. Perlite, on the other hand, will add drainage to the soil that it's mixed with.

Vermiculite finds its way into many seed starting systems. It both protects seedlings from fungus that so often ruins seed starting, and helps to retain water in the tiny little pods that seeds start in. While perlite can be used with seedlings, it’s better used when you move your seedlings into separate pots for additional drainage.
