Imerys opens its doors at its
More than 60 distributors, contractors and merchants from the UK were given a tour of Imery’s Phalempin factory in northern France to see how
it’s range of clay roof tiles are manufactured. John Mercer, technical consultant, explains more about the company’s product offering
Last month, Imerys Toiture opened the doors
to its Phalempin factory in northern France
to welcome customers from the pitched
roofing industry throughout Europe,
including 60 distributors, contractors and
merchants from the UK.
The Phalempin factory produces some of the
company’s most popular clay roof tiles, namely
the 17 x 27, 16 x 24 and Chartwell plain tiles, as
well as the fittings and accessories to match.
With a workforce of just 30 people, more
than 45,000 tonnes of clay plain tiles and 2,000
tonnes of accessories are produced annually at
Phalempin. A large majority of them are exported
to the UK, due in part to the factory’s location in
France, but also due to the quality and popularity
of the range of colours available.
The 17 x 27 Phalempin plain tile is available
in eight distinctive colours, of which amber,
weathered, rustic red, volcano and val de seine
may be used individually or can be mixed
on-site to create unique blends. The exception is
millennium blend, which is blended from several
subtle finishes and is supplied pre-mixed. Being
clay, the colours and surface textures will last for
the lifetime of the tiles.
The tile range is one of the few double-lapped
plain tiles on the UK market that can be used
on roof pitches as low as 30°. Although the
British Standard for slating and tiling – BS
5534 – recommends a minimum roof pitch of
35° for double-lapped plain tiles, the method of
manufacture enables anti-capillary channels to
be incorporated onto the Phalempin tiles’ upper
surface, ensuring enhanced performance. Winddriven
rain testing carried out independently by
BRE has enabled certification of the tiles for use
A comprehensive range of fittings and
accessories are available with Phalempin plain
tiles, including the usual tile-and-half tiles for use
at verges and side abutments, as well for cuts at
hips and valleys.
Short course tiles are available for undereaves
courses, top courses at ridge and top
abutment, and there is a choice of half round
or hogsback-profile ridge and hip tiles together
with matching clay ridge end caps. Half round
and hogsback ridge tiles, hip tiles and associated
fittings can be installed using dry fix systems
or mortar-bedded. Note, if mortar-bedding, BS
5534 requires that each ridge and hip tile be
mechanically fixed by clipping and/or screwing
to the ridge or hip timber.
Traditional bonnet hip tiles are available

for hips and an arris hip tile is also available
to suit 35° pitched roofs. Alternatively, for
designers and roofers wishing to create an ‘arris’
appearance for other roof pitches, tile-and-half
tiles can be cut in each tile course to mitre the
hip corner and weathered using lead or lead
replacement material soakers.
Universal valley tiles are available for roof
pitches from 35°-50°. Open lead or glass fibre
valleys can also be installed. For those wishing
to create a very traditional plain tile appearance,
Phalempin plain tiles are perfect for swept or
laced valley details.
Phalempin clay plain tiles are also ideal
for vertical tiling and come with the necessary
fittings to create the perfect vertical wall finish.
Left and right-handed 90° vertical angle tiles are
available for use in alternate courses at external
tiling corners. For other angles, for example,
135° or internal corners, tile-and-half tiles can
be cut to create a mitred finish, with lead or
lead-replacement soakers fitted in each course to
weather the junction. Ornamental club tiles are
also available for use in vertical tiling to create
distinctive tiling bands and patterns.
Roof space ventilation can be achieved using
soffit or over-fascia ventilation in conjunction
with dry fix ridge systems. Where additional roof
space ventilation, mechanical extraction or soil
vent pipe terminals are required, tile and ridge
ventilators are available in colours and finishes to
match the tiles and ridges.
Imerys also has a new integrated photovoltaic
system available, which is fully compatible with
Phalempin plain tiles. The PV 75 system comprises
75wp modules, that are quick and easy to install.
Weighing only 7kg, each PV module occupies an
area of half a square metre, integrating discretely
with the surrounding tiles and the supporting roof
structure. PV 75 is versatile and integrates not only
with the Imerys range of clay plain and profiled
tiles, but also with natural slate.
