Materials that are good insulators of heat include wood, fiberglass, polystyrene foam, and aerogel. These materials trap air and prevent the transfer of heat due to their low thermal conductivity. Additionally, materials like wool and cotton can also act as good insulators due to their ability to trap air and prevent heat loss.
Steel is more convenient to store than cotton because steel is denser and takes up less space for the same weight. Steel is also more durable and less susceptible to damage from environmental factors compared to cotton, which is prone to moisture, pests, and degradation. Additionally, steel can be stacked and stored in a variety of ways, making it easier to manage inventory and space.
