PRECAST WOOD FIRED PIZZA OVEN KITS
An authentic Wood Fired Oven makes the perfect centrepiece for any entertaining area. There's nothing quite like the crackle of timber burning, the rich smell of wood smoke and the cheery, twinkling light of a fire to bring people together. Then there's the food; from hand stretched pizzas cooked in 90 seconds to shoulders of meat slow-roasted for 8 hours, and everything between.
It's little wonder Wood Fired Ovens are so popular. With our PreCast Kits, we've made them simple.

HOW TO BUILD OUR PRECAST OVEN
BRICK OR PRECAST: CHOOSING THE RIGHT OVEN FOR YOU
WHAT’S INSIDE A KIT
If you're looking for a Wood Fired Oven that's easy to assemble, fits into a small space and heats up quickly then our PreCast Oven Kit is what you've been searching for. Our PreCast Oven Kits have the same front arch as their Brick Oven Kit brothers, which you'll create using our PreCut fire bricks, for an authentic, timeless look. The internal dome is made up of fibre-reinforced refractory sections, cast in CNC machined molds by our dedicated team. At every point we have looked for ways to minimise the effort taken to build this kit, without impacting on quality. We're very proud of the result.
The PreCast Oven Kit is designed for DIY; we've done all of the hard work for you - you get the fun of putting it together.
The dome of the oven is made up of four PreCast sections, which lock together perfectly using custom designed ‘tongue & groove’ joints. The first section is the entry arch, made to fit the golden ’63 percent’ rule, with the height of the opening set at 63% of the internal dome height.
The PreCast sections are made from a high grade refractory castable, reinforced with stainless steel fibres for superior strength and durability, rated to over 1350°C
The dome itself is comprised of three shell pieces, made in a special elliptical shape for optimal heat distribution, with a wall thickness of 65mm. This wall thickness gives you the perfect balance of quick heat up time, with long heat retention for roasting, bread baking and slow cooking.
The Front section, which we call the Entry Arch, has deep grooves cast into the front face which your Vent Arch firebricks will be mortared into
Just like our Brick Oven Kits, the PreCast Ovens use a 50mm thick Calcium Silicate board underneath the Firebrick floor tiles to prevent the heat in the floor from escaping into the stand below.
The 'Calsil' board comes already cut to size, with a centreline marked to help you position it on your oven stand. Calsil is an incredible high temperature insulation, with a huge compressive strength to handle the weight of the oven
The floor of your PreCast Oven is made of high-duty refractory Firebrick tiles, carefully cut to size, ready for you to bed down into a layer of refractory mortar (included in the kit).
We designed the layout of the Floor Tiles to have the joints at a 45° angle - this means that when you slide your paddle into the oven to fetch a piping hot pizza, it's less likely to catch on a raised edge. The Firebrick Tiles have a 42% Alumina content; they are very dense and have a hard-wearing surface.
To pour the keystone that locks the precast sections together we give you a domed piece of fibreglass, custom made to fit the curvature of the oven.
To set this in place you'll need to use a car jack (not included in the kit). Jack the fibreglass up until it sits firm against the cast sections, then pour the keystone with the refractory castable that's provided.
To help you position the bricks for the Vent Arch, the kit comes with a pre-assembled set of CNC Machined Formwork. Made from waterproof formply, the formwork is marked with a centre line to get it positioned accurately on the oven floor.
We also mark the mortar joints on both sides of the formwork, to show you where each mortar joint needs to be to be. If you follow the formwork, you'll lay a neat and symmetrical firebrick arch.
The Firebrick Arch at the front of the oven forms the Vent, that directs the smoke from the oven into the flue above. The firebricks are all cut to size, numbered and ready to lay around the CNC machined formwork that we have custom made to fit each oven kit.
The bricks are shaped to 'key' into the large grooves in the Precast Entry piece, for strength. The kit also includes the refractory mortar you'll need to glue these bricks together
A key part of every one of our Wood Fired Oven Kits is the PreCast Flue Gallery, made to fit snugly around the Vent Arch brickwork. Made with a high grade refractory castable, the Flue Gallery is reinforced with stainless steel fibres for strength.
The PreCast Flue Gallery comes with a stainless steel flue sleeve installed, with high density ceramic fibre rope used to form an expansion joint between the stainless steel flue and the casting
To lock the PreCast sections together the kit includes plenty of refractory castable that you'll mix up and use to create a keystone, and seal the joints between the sections.
This is the same material we use to make the cast sections in the first place, it's rated to over 1350°C with a high compressive strength and small ceramic fibres for crack resistance.
To insulate the dome of the oven we use Ceramic Fibre Blanket, supplying enough to warp the dome with two layers of 1" blanket, for a total of 50mm of insulation.
The Ceramic Fibre Blanket is such an efficient insulator that even with an internal temperature of 600°C, the outside temperature of the dome will only reach around 50°C.
To secure the Ceramic Fibre Blanket to the dome we give you plenty of 125mm galvanised nails which you'll hammer into the side of the CalSil board, and use as fixing points for the tie wire. The tie wire is used to lash the blanket down over the dome.
The chicken wire wraps over the blanket, secured to the fixing points. This gives the render something to bind to while it's wet, and gives the cured render higher tensile strength
You may be wondering how we get the render shell to be such a smooth curve - the answer is our custom-made polystyrene float. If you try to shape the dome render using an ordinary flat trowel or float, you'll end up with an uneven surface and a lot of flat spots.
The kit includes a curved polystyrene float that has been cut to the precise radius of curvature for your oven. Using this float you'll be able to get a smooth, even finish on the dome render
Perlite is a super-lightweight expanded mineral with a very low thermal conductivity, resisting temperatures up to 1000°C. It's the perfect material for making lightweight, strong, high-build render.
The kit includes enough Perlite to create a 50mm render layer over the Ceramic Fibre Blanket, providing additional insulation to the oven and a thick shell to protect the insulation blanket.
The oven door is an important component of the kit; you can use it to seal the oven chamber completely, extinguishing the fire and holding stable temperatures for roasting and baking.
The door can also be used to regulate the airflow into the oven, controlling the rate of combustion and ensuring all of the smoke goes up the chimney. Fitted with a temperature gauge and powdercoated in satin-black, it's the perfect finishing touch.
There are so many ways to trim your Wood Fired Oven, you're only limited by your imagination. The outside surface of the dome doesn't get much over 50°C during firing, so it can be covered with just about anything you want. They can be built through walls, into structures, clad in mosaic tiles, pebbles or roll-on stucco.
We have hundreds of happy customers who've trimmed their ovens in all kinds of ways, we're looking forward to seeing what you do with yours.
