Red blue blend

Dreadnought Redblue blend smoothfaced plain clay tilesRedblue blend sandfaced plain clay tilesThis colour is achieved through skilled control of the burning process to produce the traditional naturally occuring random hues of authentic multi-coloured clay roof tiles; colours that cannot be replicated artifically with stains and pigments.   The colours within this blend are rich and varied with purples & blues merging with reds and vibrant terracottas.   It is this random varied quality in the firing of this blend which results in some purply blue tiles, some terracotta red tiles and some tiles which are both red and blue.

Available as Smoothfaced/Sandfaced

Case Studies

Argent Centre, Birmingham

Winner of 2021 Victorian Society Birmingham & West Midlands Group Conservation Award

Red blue blend plain and ornamental club tiles

Argent 3Argent 4

The restoration and recreation of 2 turrets at the Argent Centre, funded by Jewellery Quarter Townscape Heritage, has been  celebrated by the Victorian Society.  Oliver Architecture used old Victorian engravings from 1863, the year the centre was built, to reconstruct the turrets at the entrance to Birmingham's Jewellery Quarter and bring back the prominance and stature of the building.  Dreadnought tiles were found to provide the most authentic match to the tiles in the original drawings and their natural clay colours best represent the subtle colour variation that tiles in the 19th century would have had.  Full details

Built on land owned by the Duchy of Cornwall, the plans for this £3.5 million School and Community Centre needed approval from the Duchy as well as the Parish and District councils.  Dreadnought’s Red Blue tiles were selected for their rich natural colour.  “Other red/blue tiles we considered were more uniform with a very similar grading of red to blue in each tile which looks artificial on a large area.  We chose Dreadnought tiles as we were looking for a product which had a natural colour generated by the firing." Sam Cook, Director at Coleman Hicks Partnership.  Full details

3600 Staffordshire Blue Bullnose, 3600 Red/Blue Blend Bullnose and 7600 Red/Blue Blend Plain tiles

Red Blue Blend  tiles at Nocton ChurchNocton Church 1

This English Heritage funded reroofing project used Staffordshire Blue bullnose ornamentals and re/blue plain tiles to recreate the old polychromatic roof with a diaper pattern.  Dreadnought is the only UK roofing tile manufacturer that does not use stains or surface pigments to colour its products, ­ colour is instead achieved by control of the kiln atmosphere. Its Red/Blue tiles, as used on All Saints, probably more than any other, exhibit the characteristics of naturally coloured tiles. The benefits of this approach include a softer, more natural colour that will not fade over time.  Full Details

“We felt we needed to use a domestic traditional roofing material to blend in with the surrounding architecture” explains Richard Ali from the Design Buro “and the planners liked Dreadnought’s red/blue colour as it fitted in well with the surrounding buildings.   Practical considerations required that the roof contain a number of air intake louvres which were cloaked to blend in with the roofline.  Dreadnought were able to supply all the fittings that we needed and we are very pleased with the result.”  Full Details

Technical Info

Frozen-Icon2 webFreeze Thaw Standards require plain clay tiles for use in the U.K. to withstand at least 150 freeze / thaw cycles under method E of European Standard EN 539-2:2013.   At Dreadnought Tiles we regard this as too low for our climate and we therefore test our tiles to withstand in excess of 400 cycles.
