This is an easily constructed wood fired oven. Design and performance of this oven is second to none. Oven wall thickness is 65mm with quality bio soluble insulation blanket backing it up. Hearth tile thickness is 50mm with 25mm of Calcium Silicate insulation board underneath. A 50mm hearth tile is the minimum you should use in your oven. This thickness allows the tile when heated through to assist in keeping the temperature in the oven for long periods. When the hearth is heated together with the walls and the insulation is of good quality, the oven’s performance will be much improved by losing minimal heat by reflecting heat back into the oven keeping it warmer for longer and also saving fuel.
