THE
CONCEPT
A
comfortable working environment has a catalytic effect on better
Quantity & Quality work output.
A
comfort ambience is normally interpreted as ambient temp in the
range of 25 °C and relative humidity around 50 %. With the high
costs of cooling homes, workplaces, business & commercial
facilities, everybody is now looking at effective options to keep
the so called " bought air" from leaving the premises.
In
spite of all control measures ,the temperature within a building is
determined by various factors based on the type of construction, the
materials used for the construction and it's degree of exposure
to Sun.
In
most cases it is the radiant heat which contributes to 90% of the
solar heat gain in any building during summer. This becomes the
major hurdle for maintaining comfort levels inside a building which
virtually becomes a ' Natural solar trap ' during summer due to
continuous radiation of absorbed heat from the roof.
Therefore curbing the Radiant heat effect is found to be the most
efficient & cost effective technique for heat controls within the
building.
The
radiant heat attacks the building from all sides, primarily the roof
which has maximum exposure to direct sunlight. The radiation from
the roof contributes to 80% of the solar heat gain of any
building.
Although we have effective methods of creating the desired ambience
in our workplace/office, the running costs are often found to be
exorbitant. The external and varying factors like the radiant heat,
results in considerable escalation of the air
conditioning costs.
This is where the Thermal Barrier Coatings are of significance. They
play a very effective role in reducing the Solar heat gain of a
building during summer and heat loss in the winter thereby saving
the extra energy lost in cooling / heating throughout all seasons.
KETHERM
•
Reflects 80-90% of the radiant heat and prevents it from being
transferred on to the substrate.
•
Restricts passage of the residual absorbed heat
into the building interior.
KETHERM -
Thermal Barrier Coatings
KISHORE POLYURETHANES PVT LTD.
The
way it works.
KETHERM
reflects Solar radiation & creates a Thermal barrier between the
coating membrane and the substrate restricting heat transfer by
conduction
The nett outcome is that only negligible quantum of the solar heat
that strikes the roof is allowed to get transferred to the base
substrate thereby providing remarkable reduction in the solar heat
gain of the building
interiors.

Graph 1 shows comparison of the solar heat gain of a building on a
32°C ambient day.
Sun
Load & Solar Heat gain
FROM THE ROOF
The above result are based on the heat gain readings taken from
inside the building after the heat has passed through the roof of
the building. ( ie.: absorbed by the roof and conducted / radiated)
The readings show that when the Sun load is 450 BTU, a steel roof
transfers 80% of the Sun load into the building whereas the roof
coated with KETHERM transfers only 23% of the Sun load.
Graph 2 shows comparison of the roof top temp.on a 32°C ambient day.

The above graph depicts the rise in roof top temp, due to solar heat
gain.
KETHERM effects a 55% - 60% reduction in the temperature gain of the
roof top.
THE PRODUCT ............... SPECIALTIES
KETHERM ... with its reflective surface has a very high Albedo. This
reflects the solar rays thereby reducing the heating effect due to
Radiant heat. The formulary of a U.V. resistant Polyurethane topping
facilitates the retention of Albedo for longer durations compared to
conventional systems.
The surface based on hi-tech Urethane technology & incorporated with
P. U. compatible air filled micro beads, functions as an effective
thermal barrier with high Thermal resistance.
The system binder being a Polyurethane formulary imparts highly
improved mechanical properties which contributes to the extended
life of the coating. It also has better ability to withstand Thermal
shock which leads to Thermal Fatigue of the base substrate resulting
in the deterioration of its strength and properties.
The system being Cast-in-situ is free of voids or joints thereby
eliminating the probability of any moisture entrapment between the
coating and the substrate unlike conventional thermal barrier
products. Moisture entrapment highly reduces the thermal resistance
of the coating.
KETHERM by it's high Albedo reflects backs of the Solar radiation.
Its high Thermal resistivity curbs the heat transfer by Conduction &
makes it an ideal thermal barrier.
