Description: The term ‘reflective’ refers to materials that have the ability to reflect light or heat, making them key elements in the design of energy-efficient solutions. These materials can be used in various applications, from construction to textiles, and are essential for optimizing energy resource use. Reflective materials often have polished surfaces or special coatings that allow them to deflect electromagnetic radiation, thereby minimizing heat and light absorption. This property not only contributes to environmental sustainability but also enhances comfort in indoor spaces by regulating temperature. In the context of architecture, for example, the use of reflective surfaces such as roofs and walls can reduce the need for air conditioning, resulting in lower energy consumption. Additionally, in the fashion industry, reflective fabrics are used to increase visibility and safety for users in low-light conditions. In summary, reflective materials are fundamental to the development of technologies and designs that seek a balance between functionality and energy efficiency.
