 Re: 42'' or 48'' oven?
Jan
48 inches really gets close to commercial sizes. If it is a backyard oven I feel the 42 inch would be the right size. The brick should be split in half at least...5 inches is not much more in the way of thermal mass than the 4.5 inches or so we would see in the US...you would also have the option of splitting it in thirds giving you just over 3 inches thickness...a thought!
