EPS (Expanded Polystyrene) sandwich panels are lightweight building materials with EPS as the core material and fiberglass panels bonded to both sides. They are widely used in the construction industry, especially in thermal insulation projects for walls, roofs, and floors. Due to their excellent thermal insulation performance (low thermal conductivity), good sound insulation, lightweight and high strength, fire resistance, and convenient construction, EPS is commonly used in energy-saving renovations and new construction projects for new civil buildings, industrial plants, cold storage facilities, and agricultural greenhouses.

In wall insulation systems, EPS sandwich panels can be made into composite wall panels to provide stable indoor temperatures. In roof insulation, EPS sandwich panels can be used as insulation layers for various structural forms such as cast-in-place concrete roofs and color steel roofs. In floor insulation, they can also be used as floor insulation layers. Furthermore, in the transportation industry, EPS sandwich panels can be used as insulation materials for refrigerated trucks, containers, and other transport equipment.
In summary, EPS sandwich panels occupy an important position in the modern construction and transportation industries due to their thermal insulation performance and wide applicability, and have been continuously developed and applied.
