ARMATHERM™THERMAL BRIDGING SOLUTIONS:
IMPROVING BUILDING ENVELOPE PERFORMANCE
Thermal bridging is a big concern in the building industry,
it has been recognised as a signi cant factor in building
envelope heat loss. By reducing heat ow through a
building’s thermal envelope we can reduce energy
consumption as well as prevent potential condensation
issues. Building codes have increased requirements of
building enclosures requiring ‘continuous insulation’
without thermal bridging. Thermal break materials can be
used to reduce heat loss in wall assemblies, transitions
and structural connections throughout the building
envelope. They can minimise building energy loss and
improve building envelope performance. This course will
provide an overview to thermal bridging, discussing the
reasons why it occurs as well as how it can be prevented.
This course will also compare building details with and
without thermal break solutions to highlight the importance
of determining accurate values of thermal transmittance.01274 591115 | [email protected] | WWW.ARMATHERM.CO.UK

n 2016 Imperial College London acquired
the neighbouring disused Royal Mail Post
Sorting Office from the Science Museum,
sitting on the corner of Exhibition Road and
Imperial College Road.
Architects Pascall+Watson were employed
to devise a sensitive yet practical design for
the change of use of this four storey building.
As part of the plans, thought had to be given
as to how to minimise carbon consumption,
as well as reduce energy use and wastage in
line with the College’s Environmental Policy.
A significant amount of heat and
energy can be lost through poor performing
windows and due to the planning
restrictions on the new Dyson Building, the
numerous beautiful original single glazed
windows of all shapes and sizes had to
be retained. Therefore, Pascall+Watson
specified secondary glazing to improve
their performance.
Over seven different types were installed to
match the varying styles; large sweepingcurved headed casements were treated with
matching sightline Series 41 side hung
casements, tall traditional box sash windows
were treated with Series 20 and 25 vertical
sliding units, along with a tricky installation
of high-level stairwell port hole windows at
the top of the building. To increase energy
performance further, the units were glazed
with 6.8 low-E laminate glass.
On the façade overlooking the service area
of the Science Museum, obscurity glass wasspecified, to prevent distractions for the
researchers and staff. The windows
overlooking the busy thoroughfares of
Exhibition Road and Imperial College Road
were fitted with a cavity to provide added
noise insulation, creating quiet conducive
spaces for learning and meetings. It was
decided to enhance the security of the ground
floor windows with Secured By Design
accredited units, the Police Preferred
Specification.
The new secondary glazing in this state-of-
the-art engineering facility, sits perfectly in
this repurposed former sorting office. The
rooms are now quiet and warm, retaining the
elegance of the original architectural features.
