Introduction
High temperature and scorching summer heat lead to discomfort even for air-conditioned environment: As such building can go to the extreme to absorb maximum solar heat through the roof which in turn increase in room temperature. An increase in room temperature results into more power consumption and further required to operate air conditioners.
There is an easy solution – you can simply use Heat Reflective Paint on a roof suitable for the same. This paint helps reflect away a considerable portion of the sun’s rays rather than let the roof soak up as much heat as regular roofing material, helping keep your home or building cooler and also making it more energy efficient. COOLROOF® provides roof cooling services for all building types and various roofing materials across India.
What Is Heat Reflective Paint?
Heat Reflective Paint is a protective coating that can be applied to the exterior of a building to reflect more sunlight and absorb less heat than a standard surface coating.
The coatings typically contain reflective materials and pigments to achieve high solar reflectance, and the absorbed heat can be dissipated via thermal emittance from the coated surface and keep it cooler when exposed to high solar intensities.
The Solar Reflectance Index is a way of measuring how well a surface reflects heat from the sun and how effectively it releases heat. If a surface is better at reflecting heat, it will have a higher value. So, inspecting the tested SRI of a product can assist property owners in making an informed decision.
Why Is Heat Reflective Paint Important in India?
Indian summers, plain concrete terraces and roofs made of metal sheets become the most difficult to handle. They are sunlit for a good number of hours in the day thereby raising the roof temperature as well as air-conditioned space heat gains.
The condition can be alleviated by applying an appropriate reflective coating. A cooler roof surface may increase comfort inside the building and cut air conditioning costs, depending on the building design, insulation, ventilation and the climate.
Indoor heat management is also important for industrial facilities, warehouses, and commercial buildings to create a more comfortable working environment. It can make a hot room below an exposed terrace much more comfortable in a residential building.
Significance of Using Heat Reflective Paint
It can become quite beneficial if you use a reflective roof coating because it can provide many benefits for your property.
Aids in Lowering Roof Surface Temperature
Reflective paint’s main function is to increase the roof’s reflectivity. When a paint product is reflective it means that it will bounce back and not absorb sunlight. This leads to lower temperature on the coated roof surface.
Supports Energy Efficiency
With less heat getting in through the roof the cooling system doesn’t need to do as much to keep inside temperatures up to scratch. This can reduce air-conditioning demand and contribute to smart energy use.
Enhances Indoor Comfort
Hot roofs in uninsulated buildings can cause rooms to become warm, especially on the upper floors, because of the heat gain through the roof. A reflective roof coating is a good option to lower this heat gain.
Protects Roof Surfaces
Specific roof coatings can include sun resistance, weathering and impact resistance based on its composition and how you will apply it. Consult the product’s data sheet for its protection.
Supports Sustainable Building Practices
Minimising extra heat gain can promote more energy-smart building management. Reflective coatings may also help green building objectives, if the coating used in the building project meets the current project needs.
Where Can Heat Reflective Paint Be Applied?
A good reflective coating can be applied on numerous types of roofs. Thus, this product is suitable for residential, commercial as well as industrial purposes. This product can be applied on various types of RCC roofs, terraces or concrete, metal roof, GI sheets, GI sheets, Asbestos as well as pre-coated roof sheets.
It is suitable for homes, apartments, industrial plants, warehouses, logistics centers, cold storage facilities, poultry farms, and other facilities with uncovered roofs. Always check surface condition and the suitability of the product prior to use.
COOLROOF®: A High-Performance Roof Cooling Solution
COOLROOF® by Indian Insulation and Engineering is formulated to prevent solar heat gains through reflective roof coatings. The brand also provides solutions for all types of roof and wall surfaces such as concrete, RCC, metallic, GI, Galvalume sheets.
COOLROOF® has an SRI value of 122, tested to ASTM E-1980, based on the product literature published by the manufacturer. The manufacturer states that the product is listed with GRIHA and has IGBC Green Pro certification, which can be relevant for certain green building projects.
According to the brand, the coating can bring down temperature of roof surface by 20°C in appropriate conditions. However, this is not always the case as real life results depend on the type of roof material, weather and quality of application and building design.
How to Choose the Right Reflective Roof Coating
There is much more to choosing a roof coating than its cost and aesthetics. Here are a few things to consider that may be helpful in making an informed decision.
And if you buy a coated panel for your roofing, first evaluate the SRI value and request the corresponding test reports. This helps you better understand the product’s reflective capacity. Then, check that the coating used will be compatible with the material of your roof. A product designed for concrete, for example, will have a different process for preparation or application when applied to sheets of metal.
Weather resistance, durability, coverage and number of coats should be checked. For bigger jobs, professional site inspection and application can ensure the coating is applied as recommended by the manufacturer.
Importance of a Professional Application
Put on a good quality coating (no matter how good it is, if you do not have it properly applied, it is not going to work out very well). The surface of the roof should be examined and ready for the coat. The roof should be dusted off, loose matter, damage, and other surface problems all need to be corrected.
Next, the coating is applied by the specified process, coverage, and dry film thickness. After application, proper inspection may reveal coverage deficiencies or areas requiring correction.
COOLROOF® offers a complete package of services from site survey to supply and application by experienced operators and final report and handover. This can simplify roof-cooling projects, especially for very large industrial and commercial buildings.
Final Thought
Indoor heat management is a challenge faced by Indian homes, commercial buildings and industrial spaces. Heat Reflective Paint provides a simple solution to combat the absorption of heat and maintain a cool, energy-efficient interior. However, selecting the paint that is suitable for the space and how to go about it is also essential.
A COOLROOF® with high SRI ratings, published test data and application support offers a roof cooling option for every building need. Before beginning a project, evaluate your roof condition, compare product specifications and seek professional advice to find the best coating for sustained performance.
