Kingspan OPTIM-R installed at exclusive
London apartments
The Kingspan OPTIM-R Balcony & Terrace System was the product of choice for a luxury apartment building right in the heart of
the capital.
Astin Burchell, Managing Director of
Partnering Contractors Limited, commented:
“The luxury nature of this development
meant it was essential that we were able to
insulate the balconies effectively, without
breaking up the minimalist design with a level
change from the indoor to outdoor spaces.
The Kingspan Balcony & Terrace System
allowed us to meet the requirements with a
simple and straightforward installation.”
20 – 40 mm thick Kingspan OPTIM-R panels
are the only vacuum insulation panels in the
world to be certified under the independent
BDA Agrément scheme. This confirms that
the products will perform as expected when
fitted to Kingspan Insulation’s
recommendations. The certification is also
recognised by bodies such as the NHBC and
LABC. This can help to streamline the
procedures and approvals process, offering
the potential for both time and cost savings.
42-43 Pall Mall is a new build
development from Amazon Property,
featuring four spacious apartments
and a flagship art gallery. Main contractors
McLaren Construction oversaw the
demolition of the existing property at 43 Pall
Mall and partial demolition of 42 Pall Mall,
with just the original portland stone façade
retained. The new apartments are spread
across both plots and have been completed
with the highest attention to detail including
bespoke kitchens and direct lift access.
To maintain excellent energy efficiency
throughout the lifespan of the building, the
scheme has been designed using a fabric-first
approach. The target roof U-value of 0.15
W/m2.K proved challenging to achieve on the
front and rear roof terraces as the elegant,
even transition between internal and external
spaces did not leave enough room for
conventional insulation. The Kingspan
OPTIM-R Balcony & Terrace System provided
a slim-line solution.
Kingspan OPTIM-R panels have an aged
thermal conductivity of 0.007 W/m.K,
allowing them to match the thermal
performance of other commonly used
insulation materials at a fraction of the
thickness. Within the Kingspan OPTIM-R

development meant it was

effectively, without breaking

Balcony & Terrace System, the panels are
accompanied with Kingspan OPTIM-R flex
infill strips which can be cut to fit unusual
dimensions.
40 mm Kingspan OPTIM-R panels were
installed on the balconies by Partnering
Contractors Limited. Matching thicknesses of
Kingspan OPTIM-R flex infill strips were also
laid around the edge of the terrace. A further
layer of Kingspan Thermataper TT47 LPC/FM
was then installed above this, providing a fall
to the gutter. The balconies were then
completed with marble tiles, providing a high
class finish.
To ensure all Kingspan OPTIM-R Systems
achieve the best possible level of thermal
performance from an absolute minimum
thickness, Kingspan’s specialist technical
team provide detailed layouts and
instructions for every project.
