The Postel clay tile is new to our range of tiles.  It originates from the Courtrai tile, which was imported into the UK from Belgium between the world wars due to a lack of indigenous supply at the time. It was particularly popular in the South-East of England.  Thousands of housing estates were covered with these tiles and many are now in need of re-roofing. In many cases a like-for-like replacement is required. As a response to this, we launched a similar product, Postel.  Properties Size: 315mm x 230mm. Minimum pitch: 20 at 70mm headlap.
