Cool roof paint is a heat reflective paint that sends a large share of incoming sunlight, especially near infrared radiation, back into the atmosphere instead of letting the roof absorb it. A conventional roof surface turns that radiation into heat and passes it indoors. A high reflective paint with high thermal emittance keeps the roof surface cooler, which reduces heat ingress into the building and lowers the load on air conditioning. The performance of any cool roof paint or heat proof paint is measured by its Solar Reflective Index (SRI).
Green Pro certified roof cooling paint systems for roofs, walls and pavements
Panache offers a Green Pro certified range of cool roof paints and heat reflective systems for roofs, walls, pavements, cycle tracks, driveways and roads. Each system works on NIR reflection technology and nanotechnology, so the surface generates less heat at the source and less heat enters the building. Choose the system that matches the substrate and the expected performance level.

Solar radiation reaches the earth as a mix of ultraviolet, visible and infrared energy. Almost 58 to 60 percent of it is infrared radiation. A standard roof absorbs this energy and converts it into heat. Roofs, walls, roads, industrial sheds, tanks and every other built structure with low reflectivity and low emissivity heat up under the sun. They pass that heat indoors and release it into the surrounding air at surface temperatures of 60 to 75 °C.
A heat reflective paint works at the surface. Its pigments and binder reflect infrared radiation away from the building, so the substrate does not heat up in the first place. Lower surface temperature means less heat conducted through the slab or sheet, and less heat released into the atmosphere.
Thermal emittance is the second property that matters. It is the ability of a surface to radiate away the heat it has absorbed, and it is especially useful in warm, sunny climates. High reflectance together with high emittance allows roofs to stay up to 20 to 28 °C cooler and walls up to 10 °C cooler than conventional materials during peak summer. The measure of a good cool surface material is its SRI value, and a well performing cool roof paint delivers an SRI above 100.
Rapid urbanisation has created concrete dense cities where surface temperatures reach up to 70 °C. The result is warmer city air and a stronger Urban Heat Island (UHI) effect. When the ambient temperature is 45 °C, a metal surface can reach 80 °C and a cement surface 65 to 70 °C. Heat proof paint addresses the problem where it starts, on the roof.
High solar gain, heat stress and hot conditions last through most of the year in India. A growing middle class, a growing construction sector and rising incomes have increased the demand for thermal comfort, and that demand is being met mainly with air conditioners, which are among the largest sources of electricity consumption in a building.
A cool roof is a reliable and environmentally friendly passive strategy. Raising the albedo, or solar reflectance, of a roof reduces unwanted solar heat gain. This saves electricity, lowers peak power demand, reduces the need for air conditioning and curbs pollution. It also cools the air around the building, which helps mitigate the UHI effect and improves air quality by slowing the reactions that produce smog.
Cool surfaces reduce UHI intensity and building cooling loads. That lowers demand for electricity and reduces greenhouse gas emissions from power plants. The effectiveness of a cool surface is assessed using several criteria, including the Solar Reflective Index and the variation in air temperature.

Cool roof paint is applied on RCC roofs, metal sheets, water tanks and other roof mounted structures of commercial buildings, offices, malls and green buildings. Roofs receive the highest solar load in a building, so a roof cooling paint gives the largest reduction in heat gain.
Roads, pathways, cycle tracks and driveways can be treated with high SRI paint to reduce the heat stored in paved surfaces and released after sunset.
Exterior walls facing the sun gain heat through the day. High SRI wall systems reduce that gain, with walls staying up to 10 °C cooler.
Cooltops Premium and Cooltops Classic, high SRI coating systems designed to reflect infrared radiation and reduce roof temperature.
A cooling and waterproofing system in one, for roofs that need both heat reduction and protection from leakage.
All Panache products are Green Pro and GRIHA certified. The company is also in the process of obtaining EPD certification, and CRRC certification for its cooling high SRI products. Use of Panache cooling products in a project reduces power costs, CO2 emissions and GHG emissions, and improves thermal comfort, health benefits, product quality and the indoor environment of the premises.

A cool roof coating consists of a binder, usually an organic or silicone compound, blended with pigments and other additives. It delivers two main benefits: protection of the roof membrane for a longer roof life cycle, and reflection of solar radiation for lower air conditioning costs.
The main components of most cool roof coatings are the binder, pigments, reflective pigments and water. Water acts as the liquid carrier that gives the coating its viscosity, so it can be spread on the roof as a thin film. Most white coatings in use today are water based.
An energy efficient white reflective elastomeric coating manufactured by Panache can reflect up to 92 percent of visible light, keeping the roof surface much cooler than aluminium, black or non-reflective roofing materials. Lower temperatures mean lower energy use and money saved. Elastomeric roof coatings also protect the roof substrate, add years to the roof and avoid costly tear-offs and re-roofing.
