The Solar Reflectance Index (SRI) is a measure of a roof surface’s ability to reflect sunlight and reduce heat transfer into the building. The SRI of a roof surface is calculated based on its solar reflectance and thermal emittance values. The Solar Reflectance Index (SRI) of a roofing material or paint can be calculated using the following formula:

SRI = (100 – T) × (SR + 0.05)^2

Where:

T = the initial (cold) temperature in degrees Celsius of the material after being exposed to the sun for a period of time

SR = the Solar Reflectance, or the amount of solar radiation reflected by the material as a percentage.

To determine the Solar Reflectance of a roofing material or paint, you would typically measure the amount of sunlight that is reflected and absorbed by the material using a spectrophotometer or similar device. You can then use the resulting data to calculate the SR and then use this value to calculate the SRI. It’s important to note that the calculation of SRI is a standard test method defined by the US Environmental Protection Agency’s Energy Star program and should be performed under controlled laboratory conditions. The SRI value provides a way to compare the relative performance of different roofing materials and paints in terms of their ability to reflect sunlight and reduce heat gain, which can help improve building energy efficiency.

Star Cool Shield Heat reflective paint reduces the surface temperature up to 31 degree celsius & ambient temperature up to 8.5 degree celsius to keep your interior cooler.

Star Cool shield Heat reflective paint is an effective product that reduces room temperature and gives strong waterproofing. The benefits of using Star Cool Shield include reducing the amount of heat absorbed by the roof, improving energy efficiency, reducing cooling costs, increasing the lifespan of the roof, and improving occupant comfort. It can also help to reduce the urban heat island effect and contribute to a more sustainable and environmentally friendly building.

Star Cool Shield has elastomeric property which reduces the possibility of cracks.

Star Cool Shield Heat Resistant Paint for Roofs has a long life of more than 8 years along with the lamination of the protective coat of Star Paint Shield+.

It can be applied to most types of roofs, including cemented, concrete, tiles, and metal. Also, you can apply it on the plastic tanks to bring down the temperature of the stored water.

The presence of nanomaterial ensures maximum reflection of IR rays from sunlight & further heat transfer, thereby reducing the amount of heat absorbed by the roof. This lowers the temperature inside the building & also the cooling costs, resulting in a longer lifespan. 

This includes regular inspections and cleaning debris and other materials from the roof with water. It is also recommended to have the painted surface inspected and recoated every few years to maintain its energy-saving benefits.

Some of the benefits of using Star Cool Shield include:

Significant reduction in energy consumption and utility costs, improved comfort and productivity in interior spaces, longer lifespan for the roof and reduced maintenance costs, Increased protection against UV radiation and weather damage, environmentally friendly solution that reduces carbon footprint, and many more.

It can be applied using a variety of methods, including spray application, roller, or brush.

Star Cool Shield offers superior heat reflection & insulation properties compared to traditional roof coatings. It is also environmentally friendly and provides longer-lasting protection against UV radiation and weather damage. So, it is a better option to apply Star Cool Shield in the same cost as compared to traditional heat reducing paints.

Yes, it can be applied on both residential & commercial roofs to provide double benefits of optimal heat reflection and increase in the aesthetic of the building.

Yes, it can be used in a variety of climates, including hot and cold environments. They are designed to provide optimal heat reflection and insulation properties in a range of temperature conditions.

It helps to reduce the need for roof maintenance by providing an additional layer of protection against UV radiation as it has Solar reflective property and weather damage. Apart from this, it also helps to prevent cracking and splitting of the roof substrate, which can lead to costly repairs.

The application of Star Cool Shield reduces the surface temperature up to 31 degrees Celsius & ambient temperature up to 8.5 degrees Celsius.

There is a considerable amount of 19.2% energy bill reduction that you can save after its application.

While it is possible to apply Star Cool Shield as a DIY project, it is generally recommended to hire a professional roofer to ensure that the coating is applied correctly and safely

Yes, it is environmentally friendly. By reducing the amount of energy needed for cooling, it can help to reduce carbon emissions and contribute to a more sustainable building. Additionally, the use of reflective materials and insulation can help to reduce the urban heat island effect and improve air quality.

The time taken to apply Star Cool Shield varies depending on the size and complexity of the roof. However, it typically takes a few days to a week to complete the application process, including preparing the roof surface, applying the coating, and allowing it to dry. Weather conditions can also impact the timeline, as the coating cannot be applied in rainy or extremely cold conditions.

The highest SRI value for Nano modified heat reflective & insulated roof coatings is 130, which is considered to be extremely high and represents excellent heat reflection and insulation properties.

Yes, it is safe for the environment. It is non-toxic and low-VOC, which means that it does not release harmful chemicals into the air during or after application. Additionally, it reduces carbon emissions and energy consumption, which makes it an eco-friendly solution for roofing.

No, there is no need of any special maintenance is required, just periodic cleaning or washing of the surface makes it long lasting & durable.

It helps to reduce energy consumption by blocking a large percentage of solar radiation and heat away from the building. This helps to keep the interior spaces cooler and reduces the need for air conditioning. As a result, building owners and managers can save on energy costs while improving overall comfort and productivity.

Yes, it helps in reducing the urban heat island effect by blocking a large percentage of solar radiation and heat away from the building. This helps to lower ambient temperatures in urban areas and reduces the demand for energy-intensive air conditioning.

Yes, it can help to extend the lifespan of a roof by providing an additional layer of protection against UV radiation and weather damage. They can also help to reduce thermal shock and prevent cracking or splitting of the roof substrate as it has thermal reflective property.

Yes, it can be customized to match a specific color or design. This can be particularly useful for buildings with specific aesthetic requirements.

It is not recommended that any existing leaks or damage should be repaired before the coating is applied to ensure optimal performance.

It can provide fire resistance benefits to some extent, depending on number of coats applied. 

Yes, it can be used on flat roofs, as well as sloped roofs.

Yes, it is a good choice for historic or heritage buildings, as it does not require any structural changes to the roof and can help improve energy efficiency without affecting the original character of the building.
