What Are EPS Sandwich Panels?

— EPS Foam Core Insulation Panels

EPS Core • Steel Face • Superior Insulation

EPS (Expanded Polystyrene) sandwich panels consist of a lightweight EPS foam core bonded between two layers of high-strength color coated steel sheets. The panels are manufactured through continuous lamination process under high temperature and pressure, creating a strong, durable, and thermally efficient building material.

Widely used for wall cladding, roofing, partition walls, and cold storage rooms. EPS sandwich panels offer excellent thermal insulation, sound reduction, and structural rigidity while remaining lightweight and easy to install.

Standards: GB/T 23932 / AS/NZS 2728 / ASTM E72.

🌡️

Thermal Insulation

EPS core provides excellent thermal insulation, reducing energy costs for heating and cooling.

⚖️

Lightweight

Approximately 10–15 kg/m² — significantly reduces structural steel weight and foundation costs.

🔇

Soundproofing

Excellent acoustic performance. Sound reduction up to 30dB depending on panel thickness.

⚡

Fast Installation

Prefabricated panels with interlocking joints. Quick assembly saves up to 50% construction time.

🏗️

Structural Strength

Steel face sheets provide high load-bearing capacity. Suitable for self-supporting wall and roof systems.

🎨

Aesthetic Finish

Smooth surface, available in multiple RAL colors. Micro-ribbed or flat profiles available.

Panel Structure

Three-Layer Composite — Steel + EPS Core + Steel

EPS Roof Type

EPS Wall Type

Total steel sheet (0.30–0.60 mm PPGI/PPGL) + EPS Core (8–30 kg/m³ density) + Total steel sheet (0.30–0.60 mm PPGI/PPGL)
