How to Build our PreCast Oven Kit | 3. Stand, Insulation & Floor Tiles

In this video we show you how to set up the optional Steel Frame stand, cut and lay your under-floor Insulation, and lay the Oven Floor Tiles. Learn more about the kit at bit.ly/2xXZbT5
'The first step'(as I like to say) in building our PreCast Oven is to set up a stand to build the oven on.
If you're in Australia we have the optional Steel Frame stands with 18mm thick compressed cement sheet benchtops available for order with your P85 PreCast Oven Kit. If you're outside Australia, fear not! We have put up detailed drawings on our website showing how the steel frame is assembled, so if you're outside Australia you could take our plans to a local steel fabricator and have them make it for you.
Once you have a stand to build the oven on, you'll need to cut out and lay the Calcium Silicate Board insulation, that isolates the oven from the stand. We see far too many DIY pizza ovens being built without any meaningful insulation underneath them, which is a shame because without good refractory insulation, a significant amount of heat will be conducted through the floor of the oven into the benchtop, and then from there into the atmosphere to be lost forever! Using the Calcium Silicate (CalSil) board underneath the oven prevents heat escaping through the base, keeping the oven floor hot, so that your pizza bases crisp up nicely.
With the insulation down, you'll need to lay the fire brick floor tiles. These come cut to size for you, ready to lay. You'll cover the CalSil board with aluminium foil to seal it, then bed the tiles down into our Hybrid Refractory Bedding Mortar mixture.

Any problems yet with the cast dome spalling ? I think the metal stand and not having to pour a foundation has me going cast instead of brick, even though I would really enjoy building a brick one. Then again wood comes at a price here in So CA so shorter fire time is a plus. I am sold on your ovens because the detailed videos and superior design than others. Keep up the good work

Thankyou!! We have never had a spalling issue with our castings, probably because we reinforce them with stainless steel fibres (the castings are 3% stainless steel by weight!) and we vibrate the castings to remove air pockets during the pour
Hey Ben I see how you use calcium silicate board which is an insulator, vs some others that use a refractory mortar sub floor. Wouldn’t it be better to use something that will allow for more thermal mass and heat saturation vs an insulator? I understand there will be much more weight but wouldn’t it help with floor temperature consistency?

Good question! You definitely want to have plenty of thermal mass in your oven floor (which we have here in the form of a 50mm dense fire brick tile) but you also need insulation, otherwise all the heat held in that thermal mass will just escape into the benchtop beneath it, and then into the atmosphere to be lost forever. You're on the right track in wanting a good amount of thermal mass, but it is **critical** to have insulation beneath that, or you will be building something that just won't achieve the floor temperatures that you're after.

@@TheFireBrickCo Thanks Ben, as usual you provide great info!
nice video. doesn't the calcium board need to be glued down to table?

It doesn't actually - the weight of the oven pins it in place. Not much sticks to the Calsil board as it's very chalky
Hi Ben, what’s the ratio of your hybrid mortar mix ? Cheers 😊

Good question! It's all in the written instructions for you; www.thefirebrickco.com
How is the calcium silicate board attached to the cement sheet?

It's not - but the weight of the oven is so great that even once the floor tiles are down it is almost impossible to shift it by pushing on it. Calsil is like chalk, so there is very little out there that will bond to it, but thankfully that isn't necessary
What are the oven floor tiles made out of? Are they the same as a medium duty fire brick?

Hi Greg! They're a 38% alumina dense fireclay brick, rated to 1350C
Is it possible to build the brick one on the stand like that?
@TheFireBrickCo

We don't recommend building a brick oven on a steel frame like this as the recommended benchtop is 120mm of reinforced concrete, which is very heavy (particularly when you add the weight of the oven itself!). While it IS possible to build a brick oven on a steel frame, it is usually cost prohibitive.
What’s the size of that stand?

This one measures 1900mm x 1900mm on the long sides but what you need will depend on the type of oven you want to build
