The insulation for the pizza oven: vermiculite.

Only high-quality materials are used for the pizza ovens in our range. However, you can strengthen the performance and energy efficiency of many pizza ovens with a suitable insulation. To do this, the round domes of the pizza ovens are walled square and then filled with the appropriate insulation material. Insulation for the pizza oven is made of vermiculite, a particularly light and efficient insulating material.

The advantages of insulation for the pizza oven

A good and comprehensively executed insulation of the pizza oven by means of vermiculite not only looks good and can change the whole appearance of the oven. Because there are several other advantages that the insulation brings. The pizza oven works more efficiently, and the risk of injury is also reduced. In addition, thanks to the insulation, the oven can be used indoors.

3,15 - 2,0 mm %
2,0 - 1,0 mm %
< 1,0 mm %

Greater efficiency through higher energy storage thanks to vermiculite

Another advantage of effective insulation using bulk material is the very effective energy storage of the insulation material. This means that the heat remains in the interior of the kiln and cannot escape further to the outside. This ensures higher efficiency, as the furnace needs to be loaded with less heating material. This factor may sound like a minimal difference at first, but with regular use, this reduction in heating materials can have a significant financial impact. Sooner or later, the cost of insulating the pizza oven will definitely pay for itself.

Minimize the risk of injury through insulation for the pizza oven

Especially in the catering industry, but also in many normal households, the pizza ovens are used without protective insulation. However, when the pizza ovens burn continuously and have corresponding temperatures inside, part of these temperatures very quickly reach the outside of the oven. A careless movement or an inconsiderate touch later, painful burns occur in the worst case. Especially families with children and professional catering, for these reasons, we always advise a comprehensive insulation for the pizza oven. If it is to be operated indoors, this insulation for the pizza oven is usually mandatory anyway in order to comply with fire safety regulations.

How to build an optimal insulation for the pizza oven

The basis for optimal insulation for a pizza oven is the structure. As a rule, the round top of the oven is provided with a square wall. It is important to size this correctly so that you do not have to use too much insulation material. Basically, a good 7 cm of space should be left between the furnace top and the wall on the sides of the brick surround. This leaves enough space for the ceramic fiber and the fill layer. Above the copings, you should allow enough space for 10 to 20 cm of insulation layer. The first step in the insulation process is to lay the ceramic fiber tightly around the furnace tops. Here, make sure that the dome is well and comprehensively covered. Now you can put the vermiculite as insulation for the pizza oven between the domes and the brickwork. Make sure that the material is well compacted without exerting too much pressure on the dome. It often helps to just lightly jiggle the material so that it can trickle into the existing gaps. Once the layer has been applied, the walling can be completed.

This is why vents must be kept clear

Even a modern and efficient insulation for the pizza oven, as offered by us, must follow certain guidelines. For this reason, it is especially important that the insulation is not completely airtight. It may certainly look attractive to plaster the oven or the entire wall afterwards, but you should leave at least two ventilation openings in the wall. Through these, the moisture that accumulates in the insulation material can disperse, so that the stove ventilates effectively on a permanent basis. This not only ensures better results, but also immensely increases the life of the pizza oven.

Vermiculite instead of your own tools

Again and again one hears from owners of pizza ovens that they do without the "expensive" insulating material and prefer to use sand or gravel from their own garden. What sounds at first like private individuals, unfortunately also occurs in the catering trade again and again. However, the pizza ovens are built in such a way that they have a certain load limit due to the dome shape. Although the ovens are stable and therefore ideally suited for normal operation, if the maximum load is exceeded, problems quickly arise. And anyone who piles up a layer of about 10 to 20 cm of sand on the dome will exceed this load limit extremely quickly. Thus, permanent damage to the oven will occur, just because the rather low price for a good insulation for the pizza oven should not be paid.

The advantage of our insulation for the pizza oven

When choosing the right insulation material, you need to pay attention to many different factors. Firstly, the weight of the material plays a not insignificant role. If the weight of the insulation is too heavy, the vault of the pizza oven can not compensate for the pressure, so the curvature may collapse. In such a case, the oven would be completely damaged and no longer usable in this form. In addition, the material used must have very good insulating properties.
Finally, it is necessary to reduce the temperature transfer to a minimum. The last aspect is also important. Because a good insulation must be able to absorb the ambient moisture. Thus, excessive moisture formation inside the furnace can be prevented. We have chosen a combination of two different materials. First, a ceramic fiber is used, which serves as the first insulation layer. In order to increase its efficiency, the bulk material is now introduced, which has the above-mentioned properties and thus provides perfect insulation for the pizza oven.

The history of “Fornace Valoriani” since 1890

A great artisan known all over the world. VALORIANI is history, quality and value. It’s HISTORY, for the business passed on five generations, each of which has been able to face and cleverly overcome the challenges of its own time, thanks to innovation and
attention to new publics’ needs. Territory and tradition: these are the characterizing elements of REFRATTARI VALORIANI Srl. The success of the company, located in Reggello (Florence), is rooted at the end of the XIX century in the Florentine area of Figline Valdarno. Here, in his own factory, the forefather of the VALORIANI’s family, Pietro, produced jars, vases and bricks made of refractory cotto. To improve the production, Gino Valoriani, the grandfather of the current owners Massimo and Valeriano, decided to move the factory to a rich clayish area located in Reggello, 20 kms away from Florence. It’s 1940 and the war was coming.

During reconstruction times, Valoriani company was out in front to help the nation restoring itself. Valoriani’s bricks were essential to build thousands of ovens necessary to bake bread in the new built houses. Then comes the watershed; Silvio Valoriani, Gino’s son, had the eureka moment: “Why don’t we build our own ovens?”. Easier said then done. He designed and built the FIRST PRE-BUILT WOOD FIRED OVEN, taking advantage of the secular experience of his family in the choice of raw materials and defining the structural design of the vault, perfect in all of its proportions, to such an extent that even today it is unchanged.In response to the great request of its products, Valoriani created its own commercial and distribution network: Alfa Refrattari, regarding the Centre/South Italy, in the 80’s sold to the current owners. During the 60’s, Valoriani came to another turning point.

Italians’ eating habits were changing, mainly because of the increased disposable income, thus Valoriani decided to create a set of pre-built wood fired ovens, called Vesuvio, addressed exclusively to professional users. Our company seems to be the only one which
produces internally the refractory both for the vault and the baking floor, with no need to adapt to what is available on the market. We receive daily marks of respect from trade associations, corporations and especially from the tens of thousands of pizza places that work every single day with our ovens.

Certifications

In the USA our professional ovens have the ETL Certification Mark, in Great Britain are approved from the CLEAN AIR 2005 No. 2304,
in Italy from UNI 10474: in 1995 from IMQ, from the CEE 84/500, from PH laboratory. Moreover our wood fire ovens have been the first,
while our gas ovens are the only one, to be approved from the AVPN (ASSOCIAZIONE VERACE PIZZA NAPOLETANA) for the baking of Neapolitan pizza.

Today, Valoriani in the World

Today the company is run by Massimo Valoriani, with the help of 25 co-workers and more than 300.000 ovens (both domestic and professional) sold. We think to be a benchmark for our experience, quality and reputation. Thanks to our models: GR, OT, IGLOO, VERACE and the new FORNOGRILL; we cover both the domestic and international market and we are well-known at an international level. Valoriani’s oven can indeed be found from Italy to Europe, the United States, Australia and Asian countries. Many other companies have tried to copy our ovens, we take that as a compliment, even if VALORIANI ovens are and will always be the one and only ORIGINALS.
