Polystyrene
Polystyrene is categorized into Expanded (EPS), Extruded (XPS), and Graphite-Enhanced polystyrene, and it serves as the primary thermal insulation material in facade construction. It is applied using specialized adhesive directly onto existing masonry, followed by the application of additional materials until the final finish is achieved.
The thermal insulation performance of polystyrene depends on the type, density, and thickness of the polystyrene board used.
