Paying high electricity bills every month is indeed a major concern for people living in hot climates. Dependency on Air Conditioners to cool the indoors becomes a necessity for hot climate area residents. However, the increasing use of AC has many adverse effects.
Using too much AC not only gets heavy on your pockets (as higher consumption of electricity leads to higher electricity bills), but also impacts your health and environment. But how else to survive the scorching heat of the sun? The best alternative to deal with this problem is installing cool roof tiles in your residential or commercial property.
The use of cool roof tiles to cool indoors is gaining popularity and is the best sustainable solution to reduce urban heat. Cool roof tiles absorb less sun heat, reflect more sunlight and keep your indoors cool and comfortable naturally. They can effectively reduce the indoor temperature by 10 to 15%.
How Does Cool Roof Tiles Work?
Cool roof tiles work essentially on 2 factors, Solar Reflectance and Thermal Emittance.
Solar reflectance simply refers to the ability to reflect the sun’s rays back. On the other hand, Thermal Emittance refers to the ability to emit the absorbed sun’s heat back to the atmosphere. This process blocks the heat from building up on the surface, which leads to reduced heat transfer to your indoors. The higher the solar reflectance and thermal emission, the cooler the surface will be.
Cool Roofs have higher SRI (Solar Reflective Index), usually greater than 90 which means they have a higher degree of solar reflectance that helps keep your indoors cool by 10 to 15 degrees Celsius.
Factors To Consider While Choosing the Cool Roof Tiles:
SRI Rating
SRI or Solar Reflective Index is one of the most crucial factors to consider while buying cool roof tiles for your building, especially for hot regions. Choose the cool roofs that havea higher SRI for maximum heat reflection. For cool roof tiles, the benchmark for SRI is above 78. However, the tiles that have SRI above 90 are most effective for improving indoor comfort in hot climate areas. Thus, choose the tiles that have SRI above 90 for optimum cooling.
Material
Different materials are used in making cool roof tiles. And, every material has its own advantages. Terracotta and Concrete tiles are the most common cool roof tiles. Terracotta tiles provide your space a natural aesthetic appeal, are generally low-maintenance, and less prone to scratches and fading. Thus, they provide a longer life span. Whereas, Concrete tiles are budget-friendly and offer a wide variety of colors and textures, allowing for customizations.
Coating
Coating is also a significant factor while choosing cool roof tiles for your space. Cool roofs tiles with glazed coating enhances their heat reflective property which helps keep the building cooler. Plus, the coating also increases the lifespan of the tiles. Thus, make sure to check this feature before making your final selection.
Durability & Maintenance
Durability and ease of maintenance are other factors to consider for cool roofs. Choose the cool roof tiles that can withstand harsh weather conditions such as high temperatures, strong winds and heavy rains. This reduces the maintenance needs and enhances the lifespan of the tiles.
Budget
Choosing the cool roofs that fits within your budget without compromising on effectiveness, durability and aesthetic needs is essential. For someone with a limited budget, there are many budget-friendly options of ceramic tiles available in the market. However, before picking the low-cost cool roof tiles one needs to understand that they might not get the best cooling result they are looking for.
