What materials are mentioned as heat repellers from solar radiation?

Concrete, stone, and brick buildings are recognized as effective heat repellers from solar radiation due to their physical properties. These materials possess high thermal mass, which allows them to absorb heat during the day while keeping the interior cooler. When sunlight strikes these building materials, they absorb and redistribute the heat slowly, preventing rapid temperature increases in the inhabited spaces. This characteristic makes them particularly effective in reducing indoor temperatures in hot climates, enhancing energy efficiency by decreasing reliance on air conditioning.

In contrast, other options like wood and glass are less effective at repelling heat because they typically have lower thermal mass and can allow more solar heat gain. Similarly, plastic and rubber are generally not built for high thermal resistance and often trap heat, while metals can conduct heat rather than repel it. Thus, the properties of concrete, stone, and brick align them with effective performance as heat repellers in building design and energy management.
