This graph shows a 27.8°C differential
of the coating placed on the outside
of the substrate (roof).
Measurements where taken on the
interior side
to show heat transfer through the substrate
(interior space).
The HeatBLOK coating substrate
showed only a 2.78°C rise in temperature
over the 32.22°C ambient day.
The bare steel (control plate) showed temperatures of 62.8°C or 30.58°C
rise from ambient*.
The white roof showed a 15.9°C
drop from the bare steel.
This test also validates that HeatBLOK outperformed
the white paint by 13.9°C.
This is a 50% reduction
over the white paint.
All substrates where tested side by side in a Controlled hot box test chamber.
The next graph shows a comparison of BTU loading of a house on a 32.22°C ambient day.
It is important to note that the coating & paint were both on the outside of the steel, therefore comparing both simultaneously.
Thermal calculations were taken from 1/8” measurements from the substrate wall
and calculated back to BTU based on heat flux.
Individual results may vary due to outside conditions, and other variables
The results above depict typical thermal loading and transfer into the substrate (i.e. commercial facility, house, etc.) based on 32.22C / 90°F ambient temperature.
The BTU transfer is taken from the inside of the substrate after it has passed through the steel substrate.
With HeatBLOK applied, approx. 90 BTU/ft/F/hr
are transmitted into the internal atmosphere.
This is reduced by 210 BTU from no insulation at all. White paint reduces the loading factor by
about ½ over no insulation, but HeatBLOK drops the loading an additional 60 BTU per hr.
These BTU numbers are important
when calculating HVAC.
As the outside substrates become hotter,
the thermal loading increases by a factor of 4.
This means that the power of heat is logarithmic and therefore becomes ever increasing
as more heat is generated.
Blocking the heat is one of the best means
to solve the logarithmic function.
Thus, the blocking of the BTU transfer becomes a great means to deal with the transfer
before it enters the interior atmosphere, not after it has made it through the substrate.
HeatBLOK becomes an excellent alternative to stop the transfer efficiently, thereby reducing the heat/cold transfer.
As far as direct monetary savings, it depends on your location, substrate and particular circumstances.
We have tried to evaluate this on a fair method below based on data acquired.
This is a guideline of savings based on the above calculations of thermal transfer.
The above graphs depict typical results of savings by using HeatBLOK coating on steel roofs.
This shows that savings may equate to 70% increase in efficiency over no insulation at all in the summer.
It is important to note that the norm is 30-50% reduction in energy costs for most environments.
Higher results may occur in very hot climates that are exposed to severe conditions.
Winter conditions also see substantial savings. Common results of 10-30% energy savings are found for most climates.
It is important to note that roof insulating coatings work best and are most efficient in
ambient conditions greater than 10°C / 50°F.
Although they work in cold climates, the coating’s have more power as the temperature becomes hotter.
This is the reasoning of why summer and winter conditions are not the same from
an efficiency standpoint.
Results obtained are only a means of estimation and cost feasibility. Actual results may vary due to
variables unknown at time of calculation.
