FAQs for wood-fired backyard pizza ovens from Armil CFSArmil CFS has been manufacturing pizza ovens for more than 10 years. Based on proven European designs, our low dome ovens heat up quickly, and when properly insulated, hold heat for hours.

Armil CFS now sells both our precast ovens and the refractory materials required to create custom ovens. Learn More about our Pizza Oven offerings.

Cast Ovens
The Armil CFS Precast Pizza Oven is cast from premium refractory and fired in our own ovens.
To achieve proper performance, the oven must be fully insulated. We recommend using our Super Isol board under the hearth. This calcium Silicate board manufactured in Europe, offers both high strength and excellent insulating characteristics. For over the top of the dome, we use either Fiberfrax Durablanket ceramic fiber blanket or Insulfrax S Blanket. Both products excel at keeping the heat in the oven. Armil CFS can also sell the castable refractory required to cast an oven. Castable refractories are designed to be mixed in high intensity mixers, and vibrated into place. To get the proper performance , manufacturer’s directions must be followed.

Armil CFS stock High Duty brick in 9×4-1/2 x 2-1/2 and 9 x 4-1/2 x 3 sizes. Call for availability on other tile sizes available. Large format 24” x 12” tiles are in stock. High Duty brick offers thermal shock resistance, temperature resistance, and heat retention These large tiles minimize joints in the hearth. We recommend using our Super J2 mortar for bonding firebrick.

Unlike other wood fired pizza oven manufacturers, Armil CFS offers only premium insulation products. Fiberfrax Durablanket S or Insulfrax S blankets are both manufactured by Unifrax in New Carlisle IN.

  • Durablanket S is a premium ceramic fiber blanket that offers excellent strength and insulating values.
  • Insulfrax S is a bio-soluble, non RCF blanket that can also be used.

While many types of insulating boards can be used for sub hearth insulation, we prefer the excellent strength and insulating capabilities of Super Isol board, made in Denmark. We recommend a minimum of 1” be used under the hearth, 1-1/2” or 2” is preferable.
