Summer in northern India has been harsher than ever before. Record temperatures not only affect those who work outside but also those who stay home. Meenaben Soni from Gujarat works as a tailor, staying indoors most of the time. Regular temperatures of 40 degrees Celsius have made working from home difficult for her. She says, “I struggled to sit next to my sewing machine and lost out on work.” Even with access to ceiling fans and electricity, improper roofing and ventilation are causing irreparable damage to livelihoods.
What is the solution for this?
Surprisingly, the answer to combat extreme heat might lie with galvanized sheets for roofs. Let us discuss below.
Circulation: The Key To Keeping Cool
To keep your house cool, it’s important to understand how heat is transferred to your home from the outdoors.
Creating a comfortable and healthy environment in any building is linked closely to air circulation. Proper circulation makes sure that fresh air constantly moves throughout the space. This prevents stagnation and maintains adequate indoor air quality, and it distributes cool air more evenly for consistent temperatures. Reliance on cooling systems is reduced, which can lead to potential energy savings.
An adequately ventilated roof system lets hot air escape and promotes cooler airflow. Installing a roof on battens ensures an air gap between the metal panels and the roof, which allows for air circulation and ventilation. This prevents heat from building up in ceiling areas. GC sheet panels are usually attached to the roof using a batten system, which promotes proper air circulation and ventilation.
Emissivity: The Release of Heat
Thermal emittance measures how effectively a roof releases the heat it absorbs. The higher the emittance, the better the material can release heat. Metal roofs have high conductivity, which makes them extremely emissive. In rural areas that experience harsh summers, after the sun heats the weather-resistant GC sheet roof, the energy spreads swiftly and emits the heat back into the air.
Reflectivity: Minimising Heat
A reflective roof reduces heat absorption while optimising the reflection of sunlight. Galvanized sheet roofing can reflect up to 70% of sunlight and when treated with reflective paint, it improves this function even further. For instance, Dipikaben Malik from Gujarat painted her metal roof with solar reflective paint that changed the indoor temperature of her home by “nearly 4 or 5 degrees”.
Metal roofs are a low-cost measure to protect rural homes and help people work and live comfortably. To know more about GC sheets and how they can help you, visit your nearest Tata Shaktee dealership.
