One of the perennial problem we encounter in our part of the world is the prevailing hot climate and very high humidity and wonder many times how to overcome the same.

With the advent of cool roof tiles, we find an easy solution in overcoming this heat menace. Cool roof tiles are a revolutionary solution to combat the scorching heat and rising energy costs associated with traditional roofing materials. Unlike conventional roofs that absorb and trap heat, cool roofs are designed to reflect sunlight and release absorbed heat, keeping the building’s interior significantly cooler.

This innovative technology offers a multitude of benefits, Viz

• Reducing energy consumption and lowering air conditioning costs.
• Mitigating the Urban Heat Island Effect (UHIE) and improving overall comfort.

In this introduction, we will explore the importance of cool roof tiles and how they contribute to a more sustainable and comfortable living environment.

What is a cool roof tiles and how it differs from regular tiles?

Cool Roof Tile is a specifically designed tile that has got the ability to reduce the heat radiation on the surface and further reduces the indoor temperature of the rooms. Thus your home is shielded from the harmful Ultraviolet (UV) radiation.

Cool Roof Tiles are manufactured using a special type of glaze that will repel heat . So, they can reflect most of the sunlight they receive and quickly radiate the heat to the surroundings. This helps to keep the base of the tiles cooler than their surfaces, thereby, providing a cooling effect to the interiors.

What are the different types of Cool roof tiles available in the market?

There are various types of cool rooftiles are available in the market as shown below

Different types of Cool roof tiles

1. Ceramic body Cool roof tiles:

• These are coming in 30×30 Cm size and the thickness varies from around 7 mm to 10 mm. For eg, Somany “TEMP SHIELD” Cool roof tiles are coming with 10mm thickness.
• Effectively reduce temperature of surface (BY 10 to 20 degree Celsius) there by making inside room cooler.
• Fights against UHIE “Urban Heat Island Effect” due to its high reflectance of sunlight & heat.
• Saves big on electricity by lowering energy demand.
• Protects your building from damage due to high heat conduction.
• Meeting guidelines set by IS standards / IGBC & CPWD for energy efficient roof.

2. Vitrified body Cool roof tiles:

• “ECO TILE” from “Pavit”
• The vitrified body cool roof tile is available in 30×30 cm size and the thickness is 10 mm
• It is mainly used to reduce the heat radiation on surface and cool down the temperature of inside area.
• Pavit white color “ECO TILE” has SRI value of 86 which reduces heat on the surface. “ECO TILE” is the ideal choice for exterior area having dual property of high SRI value and strength.
• SRI (Solar Reflectance Index) is a measure of the solar reflectance and emissivity of materials that can be used as an indicator of how hot they are likely to become when solar radiation is incident on their surface.
• It is a method of evaluating a roof’s ability to reject the solar heat.

The Standard Operating Procedure (SOP) of Cool roof Tiles laying

Cool roof tile laying is slightly different from regular tile laying and needs experienced laying team to execute it perfectly. The process of tile laying is given as under.

How can one measure the performance of a cool roof tile?

SRI (Solar Reflectance Index) is a measure of the solar reflectance and emissivity of materials that can be used as an indicator of how hot they are likely to become when solar radiation is incident on their surface. It is a method whereby one can evaluate roof’s ability to reject solar heat.

SRI (Solar Reflectance Index) values called “SRI Value” of Cool Roof tiles are in excess of 86 which is much lower in other tiles. That’s why these tiles are an ideal roofing choice for buildings in hot climates especially in places like Chennai.
