Expanded Polystyrene (EPS) is a lightweight, rigid cellular plastic made of about 98% air and 2% polystyrene. Produced by expanding polystyrene beads with steam and molding them into blocks or panels, EPS is one of the most versatile materials in modern construction.
In building applications, EPS is most commonly used as the insulating core of sandwich wall panels, roofing panels, floor slabs and cladding systems. Its remarkable strength-to-weight ratio, thermal insulation and moisture resistance make it ideal for walls that are quick to erect yet built to last.
When combined with steel wire mesh and concrete, EPS panels form monolithic structures that rival — and often outperform — traditional masonry. For homeowners and developers alike, EPS represents a smarter, faster and more affordable path to quality shelter.
