Polystyrene aggregate is recognized for its better insulation properties compared to traditional materials. This characteristic is primarily due to the air-filled structure of polystyrene beads, which significantly reduces thermal conductivity. As a result, using polystyrene aggregate in construction can lead to improved energy efficiency in buildings, making it an appealing choice for insulation applications.

In insulation applications, effective thermal performance is crucial, and polystyrene's ability to minimize heat transfer allows structures to maintain stable internal temperatures, which can ultimately lead to lower energy costs for heating and cooling. This benefit is especially relevant in residential construction, where energy efficiency standards are increasingly important.

While options such as higher density, lower cost, and difficulty in installation are aspects that may apply to various materials, they do not specifically highlight the key advantage of polystyrene aggregate in terms of insulation capabilities. The insulating properties of polystyrene aggregate serve not only as a competitive advantage in the marketplace but also promote sustainable construction practices.
