Ordering & Shipping - IMPORTANT

 NON-RETURNABLE PRODUCT 

Due to the weight, handling requirements, and high cost of shipping associated with refractory materials, all sales of refractory products are considered final. We are unable to accept cancellations, returns, or refunds once an order has been placed. We kindly ask that you review your order carefully before completing your purchase.

Ordering & Delivery:

Please note that shipping refractory materials may take up to 2 weeks from the date of order. We do not offer expedited shipping, so we strongly recommend placing your order as early as possible to avoid delays. Freight shipments are delivered by a local carrier in your area. The carrier will contact you directly to schedule your delivery date and time. To help avoid missed calls and delivery delays, please provide a secondary phone number in the Order Notes during checkout. Once an order is placed, it cannot be rerouted to a different address. Additionally, orders returned to our facility due to missed delivery or incorrect contact information are not eligible for a refund.

Shipping Charges:

Please note that FedEx, UPS, and freight carriers charge different rates based on the delivery address. Residential deliveries incur higher fees due to the added time and effort required, while commercial business addresses receive lower rates. To reduce your shipping expenses, we strongly recommend having your order delivered to a commercial business address. (Please note: home-based businesses are classified as residential and do not qualify for commercial delivery rates.)


If your order ships via freight (usually large or heavy orders on a pallet), it will arrive via a box truck. To unload the pallet, you’ll need either:


●  A forklift at the delivery location, or

●  A liftgate service, which you can request during checkout for an additional fee.


With liftgate delivery, the driver will use a hydraulic lift to lower the pallet to the ground and place it on or near your driveway. However, they are not movers and cannot transport the pallet beyond this point. If no forklift is available at your location, please be sure to select the liftgate option when placing your order to avoid delivery delays or complications.


Confirm Delivery Details to Avoid Delays -

If we are notified by the shipping carrier that the ship-to / delivery address was incorrectly classified (e.g., listed as commercial when it is actually residential), or if a liftgate service is required but was not selected during checkout, we will send you an invoice for any additional delivery fees charged to us by the carrier. Full payment of the additional fees will be required before we can authorize final delivery of your order.

When we founded BrickWood Ovens, our mission was clear: to create pizza oven kits that anyone, regardless of masonry experience, could use to build a high-performance wood-fired oven while staying on (or preferably below) budget. We went the extra mile by developing detailed, colorfully illustrated plans for both the pizza oven and its base, complete with materials lists. Best of all, we offer these pizza oven plans for free, so you can download them before ordering your kit and see just how simple it is to construct a pizza oven for your family using locally sourced masonry materials. 

 

We’ve received hundreds of 5-star reviews from customers who built their dream pizza ovens without any technical training. And we've received just as many reviews expressing gratitude for the skills, knowledge and confidence our customers gained while building their ovens from scratch which empowered them to take on additional masonry projects around their homes.

The Cortile Barile pizza oven distinguishes itself from other ovens on the market with our patented pour-and-pack foam pizza oven forms. This innovative 5-piece oven kit is made by pouring and packing castable refractory material into molds crafted from expanded polystyrene (EPS), often referred to as "Styrofoam," which is a trademarked brand name synonymous with EPS. After pouring and packing the castable refractory, a process that takes about 90 minutes, you allow it to cure for a week. Once fully cured, you can remove the foam, revealing the five pieces needed to construct the pizza oven: front, back, left side, right side, and top. When these pieces are bonded together and finished with your choice of exterior, you'll have a durable, long-lasting wood-fired pizza oven designed to last for generations

 

The construction method of this oven is similar to our dome-shaped 28" Mattone Cupola pizza oven, which also uses castable refractory poured and packed onto an EPS foam mold. While both the Cortile Barile and Mattone Cupola share similar functionality and materials (and use the same size pizza oven base), the round hearth and extra thick walls of the Mattone Cupola require an additional 260 lbs of castable refractory. This makes the Mattone Cupola ideal for extended baking sessions, whether all day or throughout the weekend. In contrast, the Cortile Barile is designed for quick heating, offering an authentic wood-fired oven experience for parties or events lasting 4 to 5 hours, as well as casual family nights with friends.

 

The Cortile Barile pizza oven kit and the Mattone Cupola pizza oven kit share similarities in construction and functionality, excelling at baking low-profile foods like breads and pizzas. However, the Cortile Barile offers a more straightforward assembly process compared to the Mattone Barile series of DIY pizza oven kits, which require more fire brick, high-temperature refractory mortar, and a greater investment of time and elbow grease. In addition to the differences in labor intensity, there are functional distinctions between the two. Both the Cortile Barile and Mattone Cupola feature a smaller oven opening and a low ceiling made of heat-retaining castable refractory. This design enhances their ability to cook low-profile foods efficiently, requiring minimal fuel while providing excellent heat retention for dishes like bread, pizzas, casseroles, and skillet dinners. Whereas the Mattone Barile series pizza ovens are designed with a larger front opening and a 19" ceiling. This design not only allows for cooking and baking low-profile foods but also accommodates larger items like turkeys and wood-fired BBQ, making them versatile for a wide range of culinary creations.

The estimated cost for a standard Cortile Barile oven build, including the base, ranges from approximately $2800 to $3000. This estimate includes the Cortile Barile • Package 1 kit  (Foam Molds, Stainless Exhaust Kit with Pipe and Ceramic Fiber Blanket).
