ROOFING & CLADDING
SIKA SARNAFIL EXPLOSIVE SUCCESS FOR ROYAL
GUNPOWDER MILLS HERITAGE ROOF REFURBISHMENT
The high-quality roofing system
was chosen after the project’s main
contractors Courtenay Builders Limited
were impressed with the results from
similar Sika Sarnafil projects. They
also entrusted Contour Roofing with
the specification and installation after
seeing its award-winning track record
with Sika Sarnafil.
The Royal Gunpowder Mills heritage site had
Sika Sarnafil products installed to guarantee a
stunning aesthetic and durable roofing solution.
A historic and archaeological treasure,
the Royal Gunpowder Mills heritage
site in Waltham Abbey, Essex, has
been given a new lease of life with
a stunning and sympathetic roof
refurbishment.

Existing Belfast Building’
Cedral refurb ad v3.indd 1
Consisting of listed buildings, ancient
monuments and natural aspect
features, the site is a well-loved
attraction. A busy hub of activity,
it attracts thousands of visitors
every year, with exhibitions and a
programme of hands-on activities for
school groups.
With previous roof coverings across the
site’s buildings close to derelict, a new
roofing system was needed that would
both guarantee a durable solution and
fit with the aesthetic of the heritage
buildings. To meet those needs, Sika
Sarnafil G410-15EL FSA Lead Grey was
specified alongside Sarnavap 1000E air
and vapour control layer.
As a site once home to tonnes
of explosives and with visitors in
throughout the refurbishment, the
project proved challenging, requiring
extensive attention to health and
safety. A strict ban on naked flames
and hot works meant that the
plywood boards had to be primed
immediately after installation and
before exposure to any wet weather.
The specification therefore considered
this and the original system, which
would have needed a completely dry
substrate, was switched to a loose laid
polyethylene air and vapour control
layer that was more equipped for a
faster installation in the expected
conditions.
Securing a 20-year Sarnafil guarantee,
the newly refurbished roofs have not
only met the client’s need for a stunning
aesthetic, but have also provided a
durable weatherproof roofing system –
upholding the heritage charity’s mission
to conserve the site for the benefit of
the general public.

Unitised curtain wall is normally
associated with new high rise building,
but in Belfast, Aluprof systems are
being used to help transform an
existing office block with a completely
new building envelope.
Located at Wellington Place in the
heart of Belfast, the Merchant Square
Office Development will offer over
200,000 sq.ft. of Grade A office
accommodation. The existing seven
storey office block was designed
by McAlister Armstrong & Partners
and completed in 1975. The new
£18.5 million redevelopment will add
two further floors and will consist of a
new Corten steel and aluminium high
performance facade.
The external envelope was originally
specified in traditional stick
construction curtain wall, but Clarke
Facades worked with Aluprof to
put forward a superior offer using
a unitised option. Crucial to this
specification change with Like
Architects of Belfast and their client,
the Oakland Group, is that the proposal
had to fall within the original facade
budget. This was achieved using
Aluprof’s MB-SE75 Capped Unitised
Curtain Wall system.
With the rise in use of unitised
curtain wall systems in medium
sized projects, the option of unitised
systems is becoming a real alternative
to a traditional curtain wall, especially
as costs are becoming much more
competitive. It is well known that
unitised systems can offer up to a 50%
time saving on installation which can
offer significant savings on the project
programme.
Aluprof’s MB-SE75 Capped Unitised
Curtain Wall system was then
specified in an anodised finish, which
then contrasts in accordance with the
architects design, with the external
Corten steel used in a vertical column
emphasis. Facade installation
started in early March and is expected
to be completed in a matter of
weeks, ensuring that the building
envelope meets the tight installation
programme.
