Staff in the new offices of a unique UK
laboratory have had their appetite for a more aesthetic view
sated by Kalzip’s standing seam roofing.
They found their outlook onto the felted flat roof of the
restaurant at Rutherford Appleton Laboratory at the Harwell
Science and Innovation Campus in Oxfordshire was uninspiring to
say the least and brought in Architects Design Partnership LLP
(ADP) to cook up a new design.
The architects specified Kalzip 400 straight and tapered stucco
embossed standing seam roofing for the £500,000 refurbishment
and extension of the restaurant which caters for the 1,200 staff
who support the work of more than 10,000 scientists and
engineers in the university research community.
Having used Kalzip numerous times before, ADP were able to avoid
a lengthy research period in finding the best solution for the
brief. The system proved ideal on a “very complicated roof for a
fairly small building” they said.
In addition to the existing roof, which is a complicated clam
shape, they constructed a lower level circular steel framed
extension which formed a series of high level clerestory glazed
openings. This in turn involved a number of complicated
flashings and roof drainage but these were “easily resolved with
on site fabrication”.
The existing roof was overclad with Kalzip to match both the
roof of the new extension and the materials used on other nearby
buildings including the distinctive Diamond light source
synchrotron facility that also boasts a Kalzip roof.
“The client wanted to carry the architectural language of the
neighbouring buildings into the appearance of the restaurant,”
said ADP’s Craig Cullimore. “One client request was to improve
the appearance of the roof of the restaurant when seen from the
new offices above in the adjacent building and they are very
pleased with the finished project, both in terms of function and
appearance. The roof unified the new extension with the existing
restaurant.”
Lee Shepherd, estimating manager for Gable (UK), the Kalzip
approved Teamkal installers, commented that it was a relatively
complicated design using a mixture of straight and tapered
sheets.
“This project outlines the versatility of the Kalzip system.
Working from an original design concept, it provides a
weathertight solution to a refurbishment project,” he said.
“It entailed installing the products onto existing felted roofs
and providing junctions with new build steelwork. These were
completed with facet curved inbound gutters and a pre curved
fascia detailed with facetted soffit planks.
“The building has a central cupola roof with facetted sheets
providing a high level turret. The roof slopes falling away from
this all have straight Kalzip sheets providing valley gutters,
fully welded to ensure a Robust Detail. The expansion was taken
up with a sliding ridge detail. Due to the nature of the design,
the verges were formed from raked sheets and then welded again,
providing a detail that provides peace of mind for the client.
“The outer section of the building was completed with tapered
sheets and again terminated with a facet curved inbound gutter
and pre curved fascia/soffit detail. Pre curved interface
details were overcome with Kalzip abutting louvres and
clerestory windows. To provide a slimline detail, the mono
ridges to the lower level were welded with the sheets falling
into the inbound gutter.”
John Dymock, contracts manager with main contractor Knowles &
Sons, added: “It was a very complex roof but Kalzip is a very
good product.”
Rutherford Appleton Laboratory is run by the Science and
Technology Facilities Council and is named after the physicists
Lord Ernest Rutherford and Sir Edward Appleton. As well as the
Diamond, it also hosts ISIS, the world’s leading pulsed neutron
source.
