The Double HP20 is the result of combining two small-format tiles into a single tile. This major technical innovation offers both the good looks of small tiles and the rapid installation of large format tiles. This 2 in 1 tile is the result of different technical aspects which we judge to be indispensable to the installation and durability of a roof.

Once installed, the appearance of the Double HP20 is very similar to that of plain tiles. Made from Beauvais clays, it offers all the quality and durability of our interlocking tiles. Moreover, thanks to its side interlocks and its invisible outlets, it offers outstanding water tightness and can be installed at roof pitches as low as 17.5°.

A successful tile in its own right, the Double HP20 also owes its popularity to the wide range of accessories that cater for all your needs and requirements. Pediment, finials, verges, ridges etc all combine to make the Double HP20 a roof that is attractive, effective and durable.
