Single ply membranes are perhaps looked
upon by some, as yesterday’s technology
– remaining current due to their high
level of performance, durability and ease
of installation. Yet, as with many other
construction technologies, they are evolving and
changing to meet the higher demands placed upon
building performance design and installation.
Changing legislation and enhanced
performance criteria to meet these changes over
the coming years is driving innovation and product
development. Standing still is no longer an option.
From a fastener manufacturer’s perspective, a
historic knowledge-base provides the foundation.
It’s less about knowing how to get on the starting
grid and more about the endeavour to get as close
as possible to pole position. Fully understanding
your product and its implementation within a
system down to the actual physicality of the
installation, gives you an insight into what can or
cannot be improved.
Like a component in a formula one car, as
other parts of the car develop and change, our
products also have to innovate and develop to
advance. To keep pace and be out in front, you
have to redesign and test and redesign and test
again. You have to take the data you have and
develop it, nurture it by adding engineering
capabilities with ingenuity and creativity.
An envelope system like any other
Good, strong competition helps drive performance
and products forward. The area of single ply
membrane roofs is no different to other envelope
systems. Base materials and decks are constantly
evolving so that attachment of the system becomes
critical to maintain and enhance the systems
performance. Modular, off-site and in-situ
construction methods are also changing and
material science is becoming a fi ne art. Beneath all
of this, the basics still have to be achieved. Pullout,
pullover, shear, thermal and weather-ability have
still to be achieved and perfected.
Ease and consistency of installation, reducing
selection issues and ensuring compatibility with the
system being installed – from deck to insulation
to membrane and on to attachment systems. All
of these should be designed with respect to the
single ply manufacturers’ system and the rigorous
standards required to meet SPRA guidelines –
which themselves develop to meet the increasing
The manufacturer’s responsibility
Component manufacturers should not simply
exist to provide a commodity product like, for
a direct analogy, a box of screws and a screw
driver. It’s our responsibility as originators to
provide the correct high-performing component
with technical back-up; from ETA’s and testing to
on-site support. Being compliant and providing
wind load calculations, on-site pullout testing
for both new and refurbishment projects should

Better by design
Brian Mack, technical business development manager at EJOT UK, discusses component manufacturing for the single ply system approach
and decks are
simply be ‘all part of the service’ – not just constantly evolving
expected, but demanded.
The building envelope has to perform for its
full lifecycle, therefore all components, no matter
how small, have to be considered. Understanding
your own manufactured component is making sure
you fully understand the system and materials and
performance of the whole application and how it
interacts with them. The holistic system approach
is becoming a fundamental aspect in construction.
The days of “pick and mix” is coming to an
end, being replaced with responsible sourcing,
sustainability and above all technical performance.
Single ply roofi ng, like the rest of the
construction industry, is facing new challenges and
the next 10 years could see the biggest changes that
it has ever experienced. It’s a challenge we have to
be ready for to drive our industry forward.
