projects where a traditional steel window appearance is
required, the EB20 range is designed to replicate the
appearance of original or existing windows while simultaneously providing all the advantages of 21st century
technology, including first rate thermal and weather
performance.
accommodate 100% recycled steel. In the UK, the infrastructure is not available to meet the demand for recycled
content above 35%, so steel is instead sourced from
Europe.
The steel used in Clement Window Group’s hot rolled
steel windows, doors and screens comes from Montanstahl in Switzerland and is made using the EAF
method meaning there is a higher proportion of recycled
steel. Montanstahl is committed to sourcing its raw
material at prestigious European mills that comply with
high levels of recycling and where profiles in the form of
hot rolled steel billets are manufactured with a very high
amount of recycled scrap metal (typically around 98%).
Scrap produced by Montanstahl as a manufacturer of steel
profiles is sold back to a mill and then also used for
recycling purposes.
Windows from the Clement EB20 range were recently
selected for the refurbishment of Ladywell Convent, the
Motherhouse of the Franciscan Missionaries of the Divine
Motherhood (FMDM) congregation, an international
religious congregation of Catholic women. Situated in
the beautiful Surrey Hills, the Convent offers hospitality
for returning Missionaries and visitors and is also the site
of La Verna, a home for elderly sisters and those who
support them.
Previously named Tuesley Court and bought by the
FMDM in 1956, Ladywell is Arts and Crafts in style,
Grade II listed and an oasis of calm and tranquility. An
extensive refurbishment was recently carried out to the
residential and conference buildings on the site ensuring
their suitability for an aging group of sisters. Two new
support buildings were also constructed.
Steel is a low maintenance material and hot dip galvanised, hot rolled type steel window frames will usually
last the lifetime of the building they are installed into,
meaning it will be a long time before they will need to be
replaced and the whole steel window cycle will being
again.
Steel is the perfect choice of framing material for many
Listed Buildings or properties in Conservation Areas and
Clement Windows specialises in replicating original
windows but with a modern specification. Designed with
this in mind, the Clement EB20 range of new double
glazed steel windows is a range of exceptionally slim
(20mm) insulated glass units manufactured with krypton
gas as standard, Part L compliant and achieving a ‘B’
WER. Manufactured from recycled steel and created for
Windows from the Clement EB20 steel window range
with 12mm oval leads were installed in the Staff Building,
polyester powder painted RAL 9005 (Jet Black) semi
gloss, providing a good match to the existing heritage
windows. The FMDM congregation was keen that the
project demonstrated a commitment to environmental
sustainability for the whole campus and the longevity and
recyclability of the new steel windows support this.
