EDUCATION: CASE STUDY

Sapa Elegance 52 curtain wall offers performance benefits for BREEAM ‘Excellent’ educational establishment
A new University Technical College in the
East End of London, specialising in the
creative and health industries, is making
full use of the performance benefits and
design flexibility offered by the Elegance 52 curtain
wall system, together with Dualframe Si 75 windows,
both manufactured by Sapa Building System.
Mulberry University Technical College (UTC)
was constructed by Wates, with the London-based
office of Scott Brownrigg responsible for the design
input. Fabricator, Cheshire Architectural Aluminium,
produced and installed the glazing package.
The project architect for Scott Brownrigg, Stuart
Cudmore, said: “There are a number of strict
regulations you have to comply with on an education
building like this, including security and general
function. The Mulberry building is on a very tight
urban site so there are parts of it that have to be
mechanically ventilated, but the top hung, Dualframe
75 SI casements provide good natural ventilation
through the main façade, as well as daylighting.
“I have employed Sapa glazing systems,
including Elegance 52 on other projects in the
past and been happy with the service and the
design effects achieved. While most of the design
assistance on this scheme came from the fabricator,
Cheshire Architectural Aluminium, Sapa was
involved in providing us with information for the
BREEAM application – where we were targeting
‘Excellent ’. As a practice we are very pleased with
the outcome of the project as a demonstration of
our expertise in the education sector.”
Not only do the internally beaded Dualframe
75 Si windows achieve an overall U-value of
1.4 Wm2K to offer very good energy saving
performance, but the system’s aluminium
construction is also highly significant from
a sustainability perspective, and therefore
contributes to the project’s BREEAM assessment.
In addition to being produced from bauxite,
one of the planet’s most plentiful natural resources,
aluminium has proved itself to be ultimately
recoverable and recyclable down the decades. This
fact allows Sapa to offer specifiers seeking the best
BREEAM ratings the opportunity to have their door,
window and curtain wall packages produced from
aluminium ingots certified as 100% recycled.

the Mulberry UTC also included Sapa ST2 entrance
doors which are PAS 24 certified for security,
while remaining fully accessible for wheelchair
users and other less able students or staff. The ST2
door frames have a level threshold subtending the
double rebated frames, and automatic openers.
Elegance 52 ST curtain walling is an externally
capped, thermally broken system that offers many
design options through the use of different mullions
and cover caps. It can deliver very good energy
and acoustic performance as well as the aesthetic
appearance to suit different property types, from
residential and retail to education or commercial.
Also stylish in design while offering multiple
opening configurations, Sapa’s Dualframe 75 Si
range is proving very popular in sectors such as
social housing, as well as education. Not only does
the uniquely designed polyamide break help it
offer U-values down to 0.9 W/m2K, but Dualframe
was the first aluminium system to achieve an A++
window energy rating with its tilt before turn window.
Additionally PAS 24 has been achieved on every style
including tilt-before-turn and pivot.
Having opened its doors to students at the start of
the academic year, the Mulberry UTC in Bow, East
London provides places for some 800 students aged
14-18. Facilities include a 250-seat theatre as well as
media suites, lecture spaces and workshop areas.
