Kalzip - Helps educate over the use of the F Word
When Carillion and PFI partner HLM Architects were
looking for materials for 13 new build primary schools
in Barnsley they knew they had to be robust, low
maintenance and sustainable … and at King’s Oak,
Kalzip’s Falzinc raised seam roofing met all those
criteria.
King’s Oak primary learning centre in the Wombwell area
of Barnsley, which has now achieved a Class A SEAM
(Schools Environmental Assessment Method), was one of
the first schools to be delivered in the £50 million
Barnsley Grouped Schools PFI project by the then Mowlem
consortia.
The project was designed to create, for the metropolitan
borough council, a new generation of single phase
primary education facilities including nursery,
reception, and key stage one and two, which also allowed
for social inclusion and lifelong learning.
The objectives of Carillion/Mowlem and their PF partners
Aqumen were to create robust, easily maintained schools
that had elements of repetition to make procurement
efficiencies, for example in the classroom and cloakroom
pods. Access for maintenance was a key issue, with a
requirement to avoid pitched roof access for routine
maintenance.
King’s Oak amalgamates two former primary schools –
Oakfield junior (on whose site it was built) and King’s
Road infants – into a £3.6 million primary learning
centre for 360 pupils comprising traditional primary
school with an integrated foundation stage and a
children’s centre with 26 nursery places.
HLM’s design solution across the primary schools was an
elemental approach to the accommodation, with
administration and staff areas grouped. Community use
rooms are grouped around the main entrance to enable out
of hours or extended use without compromising the
secuirytb of the whole school.
Their design for King’s Oak enables excellent levels of
natural daylight and ventilation, with most of the
classroom spaces facing south over the playground and
playing field and vehicular access from the north to
give good separation between pupils and vehicles as well
as giving students and teachers a summery aspect.
To combat solar gains and glare, they designed a large
roof overhang which also has the advantage of providing
shade and shelter to an outdoor teaching space. Zinc was
originally specified to complement the elevational
palate of timber, masonry and render, but the foldable
Falzinc made better use of the “very limited budget”.
HLM’s project leader Alan J Taylor said: “The
environmental design is an aspect we are particularly
proud of.”
Kalzip’s Falzinc uses a patented Pegal process to encase
the aluminium core of the raised seam with a
pre-weathered zinc layer that has a lower weather
erosion rate than zinc and is long living due to the
saline resistant substrate. The weathering treatment
gives the zinc surface a mid grey shading – the
appearance of approximately three year old natural zinc.
At King’s Oak, the Falzinc sheets were fixed by approved
installer Varla (UK) Ltd with associated flashings and
fascias as well as gutters to prevent runoff from cedar
boarding above roof level affecting the zinc.
David Russell, who was principal architect at the
council at the time of the bid, said: “The use of the
materials stretched the norm for what we had seen in PFI
schemes but most of all, the designs showed quality but
also deliverability.”
Adrian Mole of Carillion thought the roof design
particularly distinctive. “Unusually, the roof was a
combination of Falzinc and cedar board. Cedar board rain
runoff attacks the surface of zinc so special care was
needed throughout the construction period and secret
gutters were constructed to prevent future damage,” he
said.
