ADVERTORIAL: COVER STORY
Measuring at 85 000m 2 , the shopping centre will be the heart of
developments yet to be built in the area.
crisscrossing the parking areas and the busy
SASA Boulevard.
The size of the centre presented lots of
challenges and opportunities for Chartwell
and Rigifoam. However, working with Wilson
Bailey Holmes, Wentzel Abrahamson
Architects as well as SIP Project managers,
they knew that with all their help they’d be
able to do it.
Roofing sheets were in excess of 60 to
80m long and they had to be lifted up,
sometimes as high as 20m. Due to the
location in a coastal area, this resulted in
severe winds and lots of rain, so handling
the material and getting it on the roof
wasn’t easy.
Lambdaboard – Cornubia
One of the products that really helped was
the Lambdaboard supplied by Rigifoam. The
easy installation assisted in alleviating
weather challenges and the long sheets that
were installed. Rigifoam representatives
assisted with technical difficulties and
advised about which material would comply
with tenants’ specification.
“Lambdaboard has the highest R-value
(which is one of four key factors that
determine the effectiveness of an insulation
material) per 25mm on insulation, what you
buy you get.
“No reduction in thermal properties over
aging, no compressing on thickness during
installation,” says Lyle Jeffrey, national sales
manager of Rigifoam.
Being a closed cell material, it does not
absorb moisture nor is it affected by
air movement.
Lambdaboard is the only Automatic
Sprinkler Inspection Bureau (ASIB)

approved ‘combustible’ insulation material
to be installed over sprinklers, as it does not
soften, melt or drip blocking the sprinklers
heads, as is the case with thermoplastics.
With the high humidity and hot climatic
conditions experienced in KwaZulu-Natal, it
made the choice of insulation immensely
critical for this project. South Africa’s
leading retail brands such as Pick n’ Pay,
Virgin Active and Shoprite have, for some
time now, understood the benefits of
excellent insulation. For this reason,
Lambdaboard was the chosen insulation
product used on Cornubia. The rigidity and
compressive strength of Lambdaboard
means not only that the roof sheeting
integrates perfectly with the product, but it
also eliminates any thermal bridging when
used in an ‘over purlin’ design.
The flexible face Lambdaboard allows for
an aesthetically pleasing ceiling finish, and
this always exceeds the client’s high
expectations and standards on shop fitting
and overall store appeal. “Its Green Building
credentials are proven and therefore
considered an eco-friendly product,” says
Andre Wiese from Bentel Associates
International Architects.
The thermal conductivity on
Lambdaboard (0.0024 W/m.K) at 22°C means
it offers an excellent stable R Value,
therefore allowing the centre’s tenants to
truly take control of their energy costs,”
says Wiese.
The interior
The north precinct is anchored by Shoprite,
Woolworths and Edgars. It is characterised
by a double level retail environment of
fashion and department stores, lifestyle
and homeware shops as well as
convenience shopping.
Easy access, good visibility and dynamic
architecture complement the exciting retail
mix which offers young and old a great
shopping experience while also providing
them with entertainment and relaxation.
KwaZulu-Natal is renowned for its year-
round moderate weather and this scheme
captures this dynamic in a creative manner
by providing a truly unique experience
which encompasses the very essence of the
KwaZulu-Natal lifestyle.
Vote of thanks
Chartwell Roofing is proud to be associated
with the Cornubia mall, another
infrastructure development that didn’t
compromise on price to achieve the best
thermal insulation.
Chartwell Roofing expresses gratitude to
the Rigifoam team for their assistance
throughout the project. Their technical help,
prompt deliveries and general service was
excellent and contributed to delivering on
time and giving the client a superior finish.
The tenants love it as once it is laid and put
in place, it requires nothing more. It offers
superior thermal and acoustic insulation
properties and that’s what we want to offer
clients and we look forward to using
Lambdaboard again in future.
