SSC Selection Post 2022 PYQ — Question 48

The correct answer is option 4 i.e. Insulation

Insulation is used in buildings and manufacturing processes to prevent heat loss or heat gain. It acts as a barrier to the flow of heat, helping maintain desired temperatures indoors regardless of external conditions. Common insulating materials include fiberglass, foam, wool, and reflective barriers. In buildings, insulation is installed in walls, roofs, and floors to enhance energy efficiency, reduce heating and cooling costs, and improve comfort. In industrial settings, it helps maintain process temperatures, protects equipment, and increases energy savings. Effective insulation also contributes to sustainability by lowering energy consumption and reducing greenhouse gas emissions. Overall, insulation is essential for energy conservation, cost savings, and improving thermal comfort in both residential and industrial environments.
