I have read the article ‘Bye-bye Brickie' regarding Novabrik (CM, May 2006) and have to say that the Canadian company is some two centuries behind the times with its product.

There are 19th-century buildings in the Reading area that are clad in a system referred to as "Mechanical Tiling".

These are clay tiles that have been manufactured as thin bricks with a recessed upper section to allow overlapping. They are fixed to timber battens and coursed as for bricks, with ‘specials' for junctions and corners. There is a well-known British clay tile manufacturer that can produce these and the only difference, as I can see it, is concrete for clay and two centuries.
