Stop Tolerating the HEAT!
Ceramic-based Solar Heat Reflective Coating. A product for A SUSTAINABLE TOMORROW
Hot structures make the air around them hotter, thereby making the summers worse!
2023 has been the warmest year in the history of humanity and it is slated to be even warmer. This increase in heat shall make the buildings / structures (such as containers / sheds / storage tanks) even hotter.
What is the mechanism of this heating? Forty-five percent of the total solar energy is in the non- visible infrared region. Heating is a direct consequence of absorption of the infrared radiation incident on an object, such as a building. On absorbing the Solar IR, when the top slab of the building heats up, it conducts the heat to the bottom of the slab, thereafter heating the building interiors below it. The AC has to work against this absorbed heat.
The rise in the temperature shall exacerbate the effect of heat, making the buildings / structures warmer.

Will we be forced to evacuate the Middle East?
NATURE CLIMATE CHANGE PUBLISHED A STUDY CARRIED OUT BY ELFATIH ELTAHIR AND OTHERS FROM MIT: RUNNING HIGH-RESOLUTION VERSIONS OF STANDARD CLIMATE MODELS, THEY FOUND THAT MANY MAJOR CITIES IN THE REGION COULD EXCEED A TIPPING POINT FOR HUMAN SURVIVAL, EVEN IN SHADED AND WELL-VENTILATED SPACES.
WITH THE CURRENT SCENARIO, THIS IS NOT LIMITED TO MIDDLE EAST BUT IS APPLICABLE ACROSS THE GLOBE!
This results in the increase in the cooling costs along with a rise in the heat-related illnesses and mortality. When people are exposed to extreme heat, they can suffer from potentially deadly illnesses, such as heat exhaustion and heat stroke. Hot temperatures can also contribute to deaths from heart attacks, strokes, and other forms of cardiovascular disease.
In other applications such as storage tanks, there shall be a rise in the evaporation of the stored material, leading to losses. In case of temperature sensitive materials, there shall be a degradation in the properties of the material.
It is very clear that there is a need to cool structures, to bring the effects of this heating under control.
The key to cooling the structures lies in reflecting the incoming heat from the Sun and emitting the absorbed heat, to effectively lessen the heat going to the basic structure.
Enter Ganzkuhl® Solar Heat Reflecting Coating
Ganzkuhl® Reflects totally about 98.6% of the incoming heat from the Sun to ensure that the coated roof is cooler than the surrounding uncoated structures. This shall give a cooler roof, which shall result in the inner structure being cooler.
We need such products to create better living spaces.
Actual Site Results
- This is a resort in Telangana.
- The exposed terrace was coated with Ganzkuhl® after proper surface preparation.
- The temperature drop on the hot surface is more than 20°C!
- This is at a plant in Rajasthan. A part of the metal roof (not the whole roof – point to be noted!) was coated.
- Ganzkuhl Coated Side is cooler by about 7C! This shows that the high reflectivity and emissivity of Ganzkuhl reduces the impact of the heat, even on the same roof! As a point to note, the inside temperature would have probably been even lower, if the entire surface was coated with Ganzkuhl, as the entire surface would have high heat reflectivity and emissivity.
What our clients says about us
Testimonial from few of our esteemed clients for ganzkuhl
Residents of my premium project experineced greater cooling with GANZKUHL. The water seepage problem has been successfully tackled by Ganzkuhl.
Chetan Gawand
CEO, Gawand Constructions Mumbai And Navi Mumbai
With usage of GANZKUHL we have seen a sharp drop in temperature within our resort’s dining hall and office. We have good energy saving after application of Ganzkuhl this summer.

Salient features of this cool coating
High Heat Reflectivity
98.6% of the Sun’s heat is reflected. This creates a cooler interior for the building.
Waterproof Layer
Save money as no need to apply another waterproofing chemical.
Durable Walkable Surface
Roof remains usable
No impact of fungus, bacteria, or algae
The roof remains clean!
POSSIBILITIES WHERE ALL GANZKUHL CAN BE USED
Buildings with a top floor which has a terrace exposed to direct sunlight. Ganzkuhl works on temperature reduction as well as a good waterproofing coating.
Airports are the worst hit: they are large flat structures – so more heating and more water seepage.
Industries operating in metal sheds face even more hostile heating. This results in the dropping of the efficiency of the workers, due to the extreme heat. Ganzkuhl would be a good solution to reducing the heat and increasing the efficiency of the workers.
Make shift offices in containers located at all construction sites such as security cabins
Storage of Temperature Sensitive Products: Products such as Silicones are sensitive to temperature. Ganzkuhl Coating on the site shall safeguard the products from undergoing damage due to extreme heating.
Chemical Industry: During chemical storage, the rising temperatures would transfer greater heat to the inside of the storage tanks. This would result in:
- Greater evaporation: Loss in material
- Risks from the release of evaporation products
- Fire hazards, in case of volatile materials
Impact on transportation:
- The railways would need a solution to reduce the heating, as it would have a direct impact on their AC costs.
MULTI-UTILITY OF GANZKUHL® coating
Multiple Base Substrates: GanzKuhl® Coating can be used for
Concrete Slabs
Galvanized / coated Metal sheets
Cloth
Wood
Rubber Sheet (limited adherence)
- Ease of Application:
- Easily applied by brushing or with rollers.
- Can be applied by any painter following the correct instructions.
How to apply Ganzkuhl® Solar Heat Reflecting Coating
Coverage:
One kilo of GANZKUHL® covers approximately ~25 sq. ft. of area.
Surface preparation of the Roof:
- It is necessary to adequately prepare the surface of the roof by scratching or brushing, to remove any loose PCC or concrete.
- The surface then needs to be cleaned and washed thoroughly with water.
- Allow the surface to dry thoroughly prior to starting the coating.
Coating:
- The primer application is the first stage. Prepare the primer as per the formulation in the Instruction Sheet. Apply the primer on the rooftop in uniform manner.
- Once the primer coating has dried the ready mix of GANZKUHL® can be applied on the Roof Top by brushing / rolling / spraying. Allow one coat to dry, before applying the second coat.
- The drying time is usually 2~3 hours. Check the surface by touching it with any blunt object – if it does not get colored or go through, the surface is dry.
- After application of the second coat, let the coated surface be exposed to open sunlight for two days, before using the surface.
- Enjoy your cooled roof!
Simulation of Uncoated Aluminium Tank v/s Aluminium Tank coated by Ganzkuhl
We worked with a leading thermal simulation company to create a simulation to see the drop in the surface temperature due to application of Ganzkuhl.
We selected the base metal as Aluminum, as it has a high level of thermal reflectivity. This would be a good litmus test for the capabilities of Ganzkuhl.
We chose a summer day, to see the impact on a peak summer day.
We ran the numbers and the results were not surprising.
Ganzkuhl protected surface was more than 6oC to 7oC cooler than a highly reflective material like Aluminium.
If the base material is Steel or Concrete, which has poor thermal reflectivity, then the difference will be even wider.
