All tiles comply with C E Marking to British and European Standard BS EN 1304, which legislates for externally tested and verified quality of roof tiles. The tiles are independently tested to the following standards by Lucideon (approved by UKAS and the British Standards Institute):
Determination of Impermeability : BSEN 539-1:2005 Method 2 & BSEN 1304:2005
Determination of Flexural Strength : BSEN 538:1994
Determination of Frost Resistance : BSEN 539-2:2013
Ashvale clay plain tiles can be used if the pitch of your roof is between 35Ëš and 90Ëš and they are fixed in accordance with the British Standard Code of Practice for Slating & Tiling BS 5534: 2014. However, if your roof pitch is lower than 35Ëš, please contact us with details of your requirements and it is very possible we can offer a solution to guarantee the use of handcrafted plain tiles down to a pitch as low as 17.5Ëš.
Our handcrafted clay plain tiles are used extensively across the UK on refurbishments and new builds alike. Our tiles are widely accepted in Conservation Areas and and are regularly used on Churches, Historic and Listed Buildings, etc.
The Ashvale clay roof tile is one of the few hand-crafted tiles available on the market today that still involves hand forming and is not entirely manufactured on a machine. The Ashvale offers individuality in appearance and with the various colours and mixes a beauty over your roof scope. Its timeless nature and lasting quality mean the Ashvale clay roof tiles are an ideal solution for any roofing project.
Our team of experts is on hand to offer you advice and provide any information you may require. We can give detailed technical guidance and/or general roofing advice over the telephone, by email or during a site visit to suit you individual needs. Designed and produced to give the appearance of an old weathered tile, the Ashvale range look equally at home on renovation or new build projects.
The Ashvale® roof tiles are produced in Sri Lanka in a modern facility. (The factory is ISO 9001:2008 certificated). The tiles are manufactured by mechanically extruding the wet clay into a ribbon and then forming the tile by hand.
Then during humidity controlled drying a varying cross camber is created in the tile which recreates the texture and imprecision found only on roofs of a bygone era by ensuring no two tiles can be the same shape. They are then fired in modern gas tunnel kilns and packaged in wooden crates ready for shipment.
The fittings are formed entirely by hand and then dried and fired in the same manner as the tiles.
The tiles are tested in our on-site laboratory throughout their production ensuring they meet the rigorous standards required to meet the relevant British and European Standards. They are then independently tested in the UK (see our technical page for test reports and guarantees) thus meeting all the CE and European standards.
