GoxhillHand Made Plain TileHand made clay roof tiles have created many of the finest

and most distinctive roofs in Britain today. For over 300 years,

they have provided a richness of colour and texture which

becomes more attractive with age. Accessories such as feature

tiles for vertical applications and elements such as eyebrow

dormers add to the beauty of buildings whose roofs are

frequently seen as the focal point of their design.

Made for decades from our own reserves of natural alluvial

clay from the banks of the river Humber, every Goxhill Hand

Made Plain Tile is unique, with small variations providing

finished roofs of individual charm and character. All tiles are

fired in the most efficient kilns available, to ensure that quality,

durability and appearance are better today than ever, with a

standard guarantee of 60 years.

Product data

There is now widespread appreciation of the considerable

added value that plain tile roofs in natural clay can provide.

The incorporation of traditional detailing elements such as

junctions with Sussex cutting or Soldier courses, “Winchester

cutting” at verges, and features such as eyebrow dormers and

turrets illustrates just why the visual identity of plain tiled

buildings is now so highly valued by designers.

Some of today’s best contemporary building designs owe much to the

added scope that clay plain tiles have provided. In part, this is due to

their use for vertical as well as roof tiling. Originally used to provide a

lightweight means of waterproofing the upper floors of timber framed

buildings, vertical cladding is now largely used for its decorative qualities.

Formerly associated with the south east and counties such as Essex in

particular, it is now spreading due to the greater prominence of smaller

developments of distinctive properties.

The use of hand made feature tiles in shapes, such as club pattern and

internal or external angles adds distinguishing finishing touches to both

intricate and simple designs.

Goxhill Hand Made Plain Tiles are available in four standard sandfaced

colours, with the option of the “Brindle Mix” achieved by mixing colours.

Sandtoft also has an extensive range of decorative ridges and finials,

to give any roof an added touch of individuality.

AppearanceSmall variations between the tiles and the rich colouring of natural clay

provide roofs of great beauty, which become even more attractive as

they mature. Goxhill Hand Made Plain Tiles are available in four colours

as shown above. Colours can be mixed to create a weathered effect.

Brindle mix is achieved by mixing Autumn Brown (50%), Dark Chestnut

(30%) and Dark Red 20%).

CompositionSandtoft clay tiles are manufactured from naturally occurring alluvial

clay deposits which are processed, extruded or pressed and fired at

high temperatures.

in each course should be twice nailed.

twice nailed.

For rafter pitches below 60°, each tile in every fifth course should be

twice nailed.

For rafter pitches of 60° and above, each tile should be twice nailed.

In addition, a wind loading calculation should be carried out in

accordance with BS 5534 to determine any additional fixing which

may be necessary.
