Clay Plain
Tiles.
These tiles have
been used for roofing since Roman times, long before the discovery of
Blue Bangor Slates. Today the tiles are machine-made, they are as durable
as Blue Bangors, but now at less than half the price.
Hand-made Clay Plain
tiles were very popular on quality houses up to the Second World War,
their only competition being Blue Bangor slates at an equivalent price.
The post-war housing boom and the arrival of the mass production large
format concrete tile lead to the demise of clay tiles. The same applied
to Blue Bangor slates, which was replaced by Asbestos-cement slates.
Eternit Clay Tiles are produced in Stoke-on Trent, Staffordshire.
This area is synonymous
with best quality, clay tiles and pottery, for generations because of
its clay. Tegral, which is an Eternit company, distributes the range
in Ireland.
Appearance:
Eternit Clay Plain tiles are chosen for Colour Durability and Long Life.There
are 7 different colours in the Eternit machine-made range from red to
dark. In Ireland we find the Century [Ke 010] is the most popular. As
the name suggests, it is designed to resemble an old roof. It is dark
enough to satisfy most planning requirements for Blue/Black while at
the same time the hints of red will nicely compliment most hand-made
bricks.
Performance :
We have
salvaged old tiles, some over 100 years old and they are suitable for
restoration work. The most serious weathering occurs on the Northern
slopes of roofs where the water remains between the tiles in winter
and results in frost damage. The modern double-camber tile overcomes
the problem of capillary attraction.
Fixing.
Although battened @ every 4", Plain tiles are easily fixed because the
nibs dictate the margin. Plain tiles are nailed every 5th row { 3rd
row in Severe exposure). Each tile must be nailed at all perimeters,
around chimneys and other roof junctions.
Price: The price is about half the cost of Natural slate. The
roof price will escalate if the Client enhances their roof with Granny
Bonnets, Ornamentals, Finials, and intricate features. On the other
hand, no other slate or tile allows the same freedom to Design, which
the Clay Plain Tile does.
