What is the
difference between a cool roof, a white roof and a green
roof? What about solar?
There are a number of ways to use roofs
to decrease the environmental toll of our built environment,
and begin to use urban infrastructure as an agent of
adaptation and environmental services. White roofs, cool
roofs, green roofs, and photovoltaic installations can all
be effective ways to improve the environmental performance
cool roof is a roof that uses a highly reflective building
material, regardless of the color. Cool roofs can help cool
buildings, cities, and the planet by reducing the percentage
of sunlight converted to heat by the building surface. White
roofs are one type of cool roof. Cool colored roofs are
typically treated with a coating that makes them reflective.
Because white roofs have a higher reflectivity of any color,
they are generally a better choice than cool coloured
materials. One caveat is that any colorued roof made out of
metal or that has a metallic coating, will still absorb a
lot of heat (because it will have a high thermal emittance)
and is therefore not considered “cool.”
roofs are living vegetative systems located on rooftops.
Their benefits include cooling the building through shading
and insulation, reducing peak storm runoff, and potentially
growing food. Green roofs do not, however, provide enhanced
reflectivity and thus would have a negligible effect on
global temperature if they were widely implemented.
photovoltaic (PV) installations provide neither the
reflectivity benefits of a cool roof nor the storm water
management benefits of a green roof. However, PV
installations can generate clean energy, an important
benefit in our global effort to transition to a low-carbon
energy economy. Because PV installations typically do not
take up the entire surface of the roof, and sometimes
require highly reflective roofing to ensure sufficient
system efficiency, cool roofs and PV are complementary
Cool roofs, green roofs
and PV are all excellent options for improving the
environmental performance of a building. Which system or
combination of systems is most appropriate for an individual
roof will need to be evaluated on a case by case basis. We
strongly believe that each of these options have an
important role to play in reducing the environmental impact
of our cities and see plenty of room for each solution to
We do want to point out,
though, that cool metal roofs are by far the cheapest option
of the three. They are at least an order of magnitude less
expensive on a dollar per square foot basis than both green
roofs and PV. When resources are available, we certainly
encourage PV and/or vegetative roofs. However, we believe
that cool roofs are a solution that can be more readily
adopted by a larger percentage of cities globally.

Can insulation be as effective as
a cool metal roof?
most cases, the minimum level of insulation for construction
is dictated by the building code. The required minimum
R-values for ceiling insulation depend on the climate zone,
where warmer climates require less insulation than cooler
climates. Heat flows naturally from a warmer to a cooler
space. During the cooling season, heat flows from outdoors
to the building’s interior. Insulating ceilings or attics
provides an effective resistance to the flow of heat.
A cool metal
roof is designed to reflect away solar energy that strikes
the surface. By reducing the solar heat gain at the start, a
cool metal roof effectively reduces heat flow, as well.
Lower attic temperatures from the use of a cool metal roof
can actually improve the effectiveness of the insulation.
Studies show that the R-value of insulation can exhibit
variations as the temperature and humidity levels change. In
all cases, a higher temperature leads to a lower effective
R-value. Also, when insulation is compressed, the R-value is
lower than the rated value. If a roof leaks, or allows air
flow or condensation to form, the thermal efficiency of the
insulation can be diminished. Thus, the synergy between
roof/ceiling insulation and a weather tight, cool metal roof
is very important.
thickness, and the R-value, of roof insulation can certainly
help to reduce heat gain and cooling energy requirements –
but only up to a point of diminishing economic returns.
An effective and
long lasting passive cooling system can be created by the
combination of roof insulation and a cool metal roof. This
combination will maximize the solar reflectance, reduce the
roof surface temperature (as well as heat gain through the
roof deck) and optimize the thermal properties of
be noted that the role of insulation on the interior side of
the roof has little effect on mitigating urban heat island
effects. Lowering the ambient air temperature by reducing
the temperature of the roof surface with a product that has
higher solar reflectance and thermal emittance is a more
effective way to address the heat island effect.

gases are warming our planet. According to the
Intergovernmental Panel on Climate Change, the Earth’s
average temperature is on track to increase by between 2 and
7 degrees Celsius (4 to 13 degrees Fahrenheit) this century,
producing a climate never before experienced by human
civilization. This rapid change in temperature is not only
stressing ecosystems, but is also increasing the frequency
and duration of heat waves, creating serious health risks to
people around the world.
Over 60 percent
of urban surfaces are covered by roofs or pavements. About
20 to 25 percent are roofs and 30 to 45 percent are
pavements. Because these surfaces are dark and typically
absorb over 80 percent of sunlight, our built environment
heats cities and exacerbates the warming effects of climate
change. Replacing roofs and pavements with more reflective
materials could reverse this warming, turning urban surfaces
into an asset instead of a burden.
metal roofing materials reflect more sunlight than
conventional roofing materials, turning less of the sun’s
energy into heat. Increasing the reflectance of our
buildings and paved surfaces—whether through white surfaces
or reflective coloured surfaces— can reduce the temperature
of buildings, cities, and even the entire planet.
Highly reflective roofs can cool buildings, lowering
their net energy use (cooling savings minus heating
penalty) by 10 to 20 percent, if the building is
On buildings without air conditioning, a white roof can
reduce inside temperatures by 2 to 3 degrees Celsius (4
to 5 degrees Fahrenheit), making buildings more
comfortable and possibly saving lives in extreme heat
White roofs reflect
sunlight, keeping our buildings and cities cooler. For
example, a white roof in temperate or tropical regions
absorbs about 70% less sunlight than an ordinary roof.
White roofs cool the human environment as well as the
atmosphere, and reduce our need for air conditioning.
Not just white
Reflective surfaces do not need to be white. Materials
such as Colourcoil high performance pre-painted steel
for metal roofing with high solar-reflectance can come
in a range of colours, including many shades of gray and
red. Hence the term “cool metal roofs”.
City-wide installations of reflective roofs and
pavements reduce city temperatures. Studies show that
cool surfaces, along with the planting of shade trees,
can reduce a city’s air temperature by 2 to 3 degrees
Celsius (4 to 5 degrees Fahrenheit), in summer months.2
This reduction not only makes the city more comfortable,
but also improves the air quality because smog forms
more readily on hot days. According to a study of the
Los Angeles basin, a combination of lighter surfaces and
shade trees could reduce exposure to unhealthy air by 10
Permanently replacing the world’s roofs and
pavements with highly reflective materials will have a
cooling effect equivalent to reducing green house gas
emissions by 44 billion tonnes of CO2, an amount roughly
equal to one year of global man-made emissions.4
Assuming the average car emits 4 tonnes of CO2 per year,
these savings are roughly equivalent to taking all of
the world’s approximately 1 billion cars off the road
for 11 years.

Nation-wide Seminars on “KOOL
Energy Efficient Pre-Painted Steel for Metal Roofing”
Colourcoil Industries is currently organising
a nationwide series of mini-seminars on “KOOL Energy
Efficient Pre-Painted Steel for Metal Roofing”. These
seminars are conducted at government and private offices and
leading hotels at selected cities all over Malaysia.
This is a follow-up to the
main seminar on the same topic, which was held in
November 2010 at the Sabah state capital of Kota Kinabalu
where more than 100 participants attended to special
speaker, Mr. Scott Kriner, the President of Green Metal
Consulting, Inc. in the United States of America.
In Sabah, the first seminar this year was
held in the Island of Pearl, Labuan F.T. on March 4th at
Tiara Hotel, Labuan followed by one in Sandakan on April 6th
which was attended by developers, building designers and
consultants, rolformers, architects and engineers from both
the government and private sector. Meanwhile, in Peninsular
Malaysia, the seminar has been conducted in Penang and Kedah
on May 5th and 25th, respectively and both to the Jabatan
Kerja Raya (JKR) or Public Works Department of the states.
Among the major topics of concern highlighted to
participants in all seminars were the need for Cool Metal
Roofs for sustainable building designs and energy cost
reduction, various concepts associated with it eg. Urban
Heat Island effect, green building rating tools such as
Malaysia’s Green Building Index and new trends in the
pre-painted steel industry in general.

Colourcoil Industries was proud to have
two visitations recently.
The first one was from the
Sabah state’s Kementerian Kesihatan or Health Department of
Sabah on 27 April 2011. They comprised of about 15 engineers
from main headquarters in Kota Kinabalu whose main roles
were to monitor all construction development of hospitals
and clinics in the state.
The second visit we were
delighted to have were more than 55 students and teachers
from Sabah Tshung Tsin Secondary School. The group comprised
of students from Form 5, Commerce Stream class.
Colourcoil Industries was
indeed proud to be able to host the younger generation and
future leaders of the state. For most of them, it was the
first time visiting a manufacturing company. We wish them
the best in their studies.
Should you wish to organize a technical or educational visit
to Colourcoil Industries, we would be more than happy to
have you. Write in to us with your contact number and we
shall contact you soon to arrange it!
