CASE STUDY

DURISOL TRANSFORMER THERMAL BARRIERS
In 2011, Yukon Energy built a new
172km long, 138kV transmission line
from Carmacks to Stewart Crossing in
the central Yukon Territory with the
goal of connecting their northern and
southern grids. Having one integrated
transmission system has given Yukon
Energy the ability to better manage
their power and part of the recent
infrastructure expansion was a new
transformer station located in Stewart
Crossing. Tetra Tech, a leading
Canadian engineering firm with
expertise in energy, infrastructure and
mining, was engaged to design the
new station.
Durisol sound barriers are a lightweight,
patented product made from recycled
wood fibers and concrete and has
been manufactured for over 30 years
as an absorptive sound wall. Most
importantly, Durisol is rated
non-combustible when tested in
accordance with the Standard for Fire
Tests of Building Construction and
Materials, ULC-263.
Transformer thermal barrier
After careful research, Tetra Tech
determined that the Durisol wall was
the best product to meet the required
two-hour fire rating. In this case Tetra
Tech elected to provide Armtec with
the steel column layout. Armtec also
has the in-house ability to design the
steel columns required for thermal
walls but it was decided that Tetra
Tech would be better equipped to
handle this portion of the scope
because pile supports were required
for the infrastructure at the site.
Assembly proceeded smoothly and
was completed by FMI Installations
with a four man crew in two days. The
Durisol facing panels were first clipped
over the steel columns. Panels were
then lifted by a small crane and
lowered between the flanges of the
two steel columns.
Durisol steel column facing panels clip on easily
and provide a 2 hour fire rating.
Armtec is a leading Canadian infrastructure and construction materials company combining creative
engineered solutions, relevant advice, dedicated people, proven products and a national presence with

“We were expecting some difficulty as
this was our first time installing the
Durisol product. The installation ended
up being the easiest part of the
project”

The test exerts two hours of flame at
1,800 degrees Fahrenheit followed by
a fire hose test, after which double its
working structural load is applied.
