What is EPS Sandwich Panel?

EPS Sandwich Panel is a lightweight, energy-saving wall panel made with a core of EPS (Expanded Polystyrene) foam mixed with cement, and surface layers of calcium silicate board or cement fiberboard. Manufactured through a one-time compound process, these panels provide excellent thermal insulation, fire resistance, and soundproofing.

They are widely used for interior partitions and exterior walls in high-rise buildings, offices, condos, hotels, warehouses, duplexes, hospitals, schools, villas, and temporary shelters.
