15. Igloo Enclosure
Overview
The Igloo is a traditional Italian and Mediterranean pizza
oven design style where the enclosure follows the basic
lines of the oven dome and chimney -- thus the Igloo.
Instructions
There are two ways of making the Igloo shape, both of
which follow the guidelines set forth in Graphics 15.1 and
15.2. First, you can create the Igloo using stucco lathe
following the shape of the oven an insulation. The insulating
layer, either FB Blanket or a combination of FB Blanket and
insulating concrete is covered with a finish coat of
waterproof stucco (see Photo 15.3 and 15.5).
Second, the Igloo shape can be created with rebar and
stucco lathe, separately from the dome (see Photo 15.4).
Drill 1/4” holes around the perimeter of the oven hearth, the
distance you want away from the exterior of your oven, to
accommodate your insulation thickness. Insert pieces of
pencil rebar in the holes, and bend them to the desired
Igloo shape. Cover the pencil rebar with stucco mesh, and
secure it in place with concrete tie wire to make the Igloo
frame solid.
Fill the gap between the stucco mesh and the oven with a
vermiculite-based insulating concrete. Cover the entire
structure with a 1/2"-3/4" undercoat of stucco, followed by a
finish stucco coat, and then, seal the entire oven with a
weatherproof stucco coat or paint.
