EPS cement sandwich panel is an innovative, lightweight composite wall panel that has transformed modern construction. It consists of two outer layers of calcium silicate board or fiber cement board, with a core made of EPS (expanded polystyrene) beads mixed with cement, sand, and additives — all compounded in a single-step manufacturing process. This unique sandwich structure gives the panel an exceptional combination of light weight, high strength, fireproofing, waterproofing, sound insulation, and thermal insulation.
As a leading EPS wall panel manufacturer since 2009, Hanmero produces EPS cement sandwich panels that meet international standards (CE, ISO9001, ISO14001, SGS certified) and are exported to over 90 countries worldwide. Whether you are building residential apartments, commercial offices, hospitals, schools, or prefabricated buildings, our EPS sandwich wall panels deliver superior performance at a competitive cost.
Quick Facts: Hanmero EPS cement sandwich panels are 3-5x faster to install than traditional brick walls, reduce building weight by up to 70%, and can lower overall construction costs by 20-40%.
The EPS sandwich panel adopts a three-layer sandwich structure, each layer serving a critical function:
Calcium silicate board or fiber cement board (5mm thick). Provides mechanical strength, fire resistance, and a smooth surface ready for finishing — no plastering required.
EPS beads + cement + sand + additives. The EPS foam provides thermal and acoustic insulation while dramatically reducing weight. The cement matrix ensures structural integrity and fire resistance.
Calcium silicate board or fiber cement board (5mm thick). Matches the outer layer, providing balanced strength and a paintable, tileable, or wallpaper-ready interior surface.

Hanmero EPS wall panels offer a comprehensive set of benefits that make them the preferred choice for modern construction projects worldwide:
Only 45-60 kg/panel — approximately 1/7 the weight of traditional brick walls of equivalent thickness. This dramatically reduces structural load, foundation costs, and transportation expenses. Each panel can be easily carried and positioned by 1-2 workers, eliminating the need for heavy lifting equipment.
Achieves 3-4 hour fire resistance rating, meeting Class A fireproof standards. The calcium silicate board surface is non-combustible, and the cement-EPS core self-extinguishes, making fireproof EPS wall panels ideal for hospitals, schools, high-rises, and public buildings where fire safety is critical.
Soundproof EPS wall panels effectively block airborne and impact noise. A 90mm panel achieves 35-45 dB sound reduction — meeting hotel and hospital acoustic standards. Ideal for EPS partition wall panels in apartments, offices, and multi-family buildings.
Water absorption rate below 10%. The dense surface boards and cement matrix prevent water penetration, making waterproof EPS wall panels suitable for bathrooms, kitchens, basements, and humid climates. No mold, no swelling, no deformation.
Thermal conductivity of only 0.12-0.18 W/(m·K) — far superior to solid brick walls. EPS insulated wall panels and thermal insulation wall panels reduce heating and cooling energy costs by up to 40-60%, qualifying for green building certifications in many countries.
3-5x faster than brick wall construction. One panel covers ~1.38m² and installs in minutes. The tongue-and-groove joint system ensures precision alignment. A 100m² wall can be completed by a 3-person crew in just 1-2 days — dramatically reducing labor costs and project timelines.
High strength EPS wall panels with compressive strength ≥3.5 MPa and hanging load capacity ≥100 kg per point. Withstands 8.0 magnitude seismic forces. Durable EPS wall panels have a service life exceeding 50 years with minimal maintenance.
Eco-friendly EPS wall panels use recyclable materials and produce zero harmful emissions. No asbestos, no formaldehyde. Energy efficient wall panels contribute to green building ratings (LEED, BREEAM, Green Star). Manufacturing process consumes 60% less energy than traditional brick production.

Hanmero EPS building wall panels are versatile and suitable for a wide range of construction applications. Their lightweight, fireproof, and energy-saving properties make them the ideal choice for:
EPS wall panels for apartment buildings, villas, and single-family homes — both interior partitions and exterior walls.
Offices, shopping malls, hotels — EPS partition wall panels provide fast construction and excellent sound insulation.
Fireproof and soundproof requirements are critical. Fireproof EPS wall panels meet strict building codes for public facilities.
Factories and warehouses benefit from fast installation wall panels that reduce construction time and costs.
Sandwich wall panels for prefabricated building projects — lightweight panels are ideal for steel-frame and modular construction.
Lightweight EPS interior wall panels are perfect for adding partitions or extending existing buildings without reinforcing the structure.
Easy installation EPS panels are one of the biggest advantages of our product. The tongue-and-groove joint system allows for fast, precise assembly. Here is the standard installation process:
Clean the floor surface, use infrared leveling tools to mark base lines. Carry the EPS wall panel to the designated position — each panel is lightweight enough for 1-2 workers.
Use a handheld electric cutter to cut the panel according to wall dimensions. EPS concrete wall panels can be easily cut, grooved, and drilled for electrical conduits and switch boxes.
Mix cement adhesive with water per specification. Apply adhesive along the base line and into the panel grooves. Position the panel, check vertical alignment with a guiding rule, and secure with L-shaped steel bars at the floor connection.
Insert steel bars at panel connection corners for reinforcement. After 24 hours, inspect for gaps between panels or at the ceiling — fill with adhesive or PU foam.
Apply anti-crack tape or fiber mesh cloth at joints (3-5 days after installation). Then finish with paint, tiles, wallpaper, PVC panels, or any decorative material — no plastering needed except for paint finishes.
