Building your Belforno Pizza Oven
This page outlines how to assemble our oven kits, from preparation to polish. Click on the images below to open up an image gallery slideshow that details each part of the process.


Preparing the foundation


The Belforno oven is always constructed on a purpose-made base to the owners design. There are any number of ways to finish the base, from simple and classic to something grand.


But all ovens require some forethought. For example, the final height of the oven floor must be considered, then planned for.


The Belforno oven kit includes space-age ceramic board insulation that sits on top of the base and under the oven floor. As an even greater heat-retaining measure, you can add a layer of vermiculite insulation.


Once you have the base in place you are ready to assemble the oven.

Oven assembly

Belforno ovens are created in separate parts that have overlapping joints. Once you have determined the location of the front of the oven, assembly begins.


First, the oven floor is laid out on top of the ceramic board, then the dome is assembled. The individual pieces are numbered, so it is a simple job to place everything in its correct position.


A little of the high-heat ready-to-use mortar is buttered along matching surfaces. And once the oven is assembled the joins and small gaps are smoothed over with a little more mortar.

Adding insulation

The keys to a good oven (a bel forno!) are good refractory material, and adequate insulation. At Belforno we believe in excellence, so 3 layers of 1” ceramic blanket is provided in the kit.


To install, wrap the oven with the blanket, one layer at a time, taking care to slightly overlap at the edges. To provide even greater insulation we recommend the use of vermiculite.


If you are planning a classic igloo shape, you will apply a wet mix of vermiculite over the ceramic blanket. If you plan to enclose your oven in a structure, loose vermiculite is used.


We supply vermiculite in ready-mix bags at a reasonable price. To apply the vermiculite, cover the ceramic blanket with common poultry mesh, then simply apply and shape by hand.


The finished product

The finished product

The final finish depends entirely on your personal taste. Some prefer a simple igloo shape, and others prefer the oven to be enclosed.


There are many creative ways to finish the outside of an igloo, for example pigmented stucco. tiles, or mosaic – to name a few. And likewise there are many ways to finish the surface of an enclosed oven – for example brick, stone, stucco or even copper.


Whatever finish you decide on, at the heart will be a Belforno oven ready to give decades of pleasure and enjoyment. We hope you decide to join the Belforno family.
