Measurements of the substructure
Measurements of the substructure Size of the substructure Now that we know
the size of the oven floor and the shape of the vault, we can calculate the
measurements of the substructure: For the length we need the sum of: the
thickness of the wall of the oven mouth (approx. 20 cm) + the length of the
oven floor + the thickness of the vault ( approx. 20 cm) + the thickness of
the insulation layer ( approx. 10 cm) + if necessary, the thickness of the
outer wall ( approx. 20 cm), depending on if you close the rear side or not
For the width we need the sum of: 2 x the thickness of the outer wall ( 2 x
approx. 10-20 cm) + The width of the oven floor + 2 x the thickness of the
vault ( 2 x approx. 20 cm) + 2 x the thickness of the insulation layer (2 x
approx. 10 cm) + 2 x open space of minimally 1 cm between loam layer and
outer wall Working height of the substructure The working height is equal
to the height of the substructure plus the thickness of the oven floor.
Usually it is between 80 cm...
