e. INSULATION
NOTE: Use safety mask when handling ceramic blanket.
Never let the insulation get wet. Always
thoroughly seal the oven against water penetration. Failure to do so can lead to breakdown of
components.
Sufficient ceramic blanket material is provided in the kit
for 3” of insulation. The blanket is 1’ thick and
must be applied in 3 layers. The blanket is flexible and pliable. To insulate, wrap lengths around the oven,
the cut extra material with sharp knife, scissors or shears, to follow the form of the oven. Pieces should
overlap by about 2 or more inches. Sufficient blanket is supplied to give three layers. If there is any
blanket remaining this may be applied to the top for even more insulation. (Fig. 4)

FINISHING THE OVEN
NOTE:
IN EXTERIOR INSTALLATIONS WE RECOMMEND TO COVERING THE INSULATION WITH A
1" LAYER OF MORTAR APPLIED OVER 1/2" GAUGE CHICKEN WIRE
ALWAYS ENSURE THE OVEN IS COMPLETELY PROTECTED FROM WATER PENETRATION
When the oven has been assembled it is ready for external finishing. This will entail finishing the oven in
an igloo shape, or enclosing the dome inside a structure with some form of protective roof. This guide is
only able to provide the most basic of ideas and methods. For more ideas look online, or contact Belforno
to discuss
IGLOO DESIGN (Figure 5)
If the oven is an igloo shape apply minimum
1” layer of ordinary mortar over ½” gauge chicken wire
carefully laid over the ceramic blanket. The chicken wire can be held in place with one or two horizontal
strands of fine gauge wire, near the base and if necessary one or two strands higher up. Once the
chicken wire is in position, apply the layers of vermiculite/ mortar, or mortar, over the ceramic blanket.
Allow each layer to set before applying further layers.
When the mortar has set, cut and remove wire stays with wire cutters.
