Tseason Expanded Polystyrene (EPS) Sandwich Panels deliver cost-effective thermal insulation and structural performance for warehouses, prefabricated buildings, and light industrial enclosures. The EPS foam core provides a thermal conductivity of λ = 0.032–0.038 W/(m·K) combining low weight with stable insulation efficiency across a wide temperature range of –30°C to +70°C.
Available in standard thicknesses of 50 / 75 / 100 / 120 / 150 mm, each panel features a PPGL steel facing on both surfaces, with optional PVDF or silicon-modified PE coatings for enhanced weather resistance and longevity.
All Tseason EPS sandwich panels are manufactured under CE certification and ISO 9001 quality management standards, ensuring consistent performance for export projects worldwide.
Tseason Expanded Polystyrene Sandwich Panels are engineered for warehouses, logistics centers, prefabricated structures, and light industrial buildings. The lightweight EPS foam core bonds firmly with steel facings to deliver reliable thermal insulation, structural stability, and moisture resistance — reducing material costs and installation time on every project.
Ordinary EPS Sandwich Panel is the abbreviation of exploitable polystyrene board. Apolystyrene foam sheet with a closed cell structure is prepared by heating the exploitable polystyrene beads in a mold after pre-foaming with heating.
Flame retardant EPS board adopts particle fire insulation film technology, the use of copolymerization modification to make EPS monomer particles have the same characteristics of fireproof substances, and the use of microphase composite technology to form a fire insulation film on the surface of each organic particle.so that each particle forms a relatively independent organic particle fire prevention unit.

Regarding structural design, Tseason EPS wall panels adopt a unique tongue-and-groove design, which makes the joints between panels tighter and more stable. At the same time, the surface can be flat or slotted to meet the needs of different application scenarios, while the EPS roof panel adopts a corrugated design, which not only enhances the strength of the panels but also facilitates the smooth drainage of rainwater.
