Question
How does insulation help maintain room temperature?
✓
Answer
Insulation helps maintain room temperature by reducing heat transfer. In winter, it prevents heat from escaping, keeping the room warmer, while in summer, it stops outside heat from entering, keeping it cooler. This is achieved because insulation materials are poor conductors of heat, effectively slowing down the flow of heat in or out of the room.
