EPS Lightweight Concrete Panels – A Next-Gen Building Solution

1. What Are EPS Lightweight Concrete Panels?

EPS lightweight concrete panels are a modern construction material made from a core mixture of cement, expanded polystyrene (EPS) beads, fly ash, and additives. This core is sandwiched between two outer layers of durable fiber-cement boards (Cemboard), forming a sturdy, lightweight panel with excellent thermal insulation, fire resistance, and soundproofing properties.

These panels are designed to replace traditional bricks in various applications such as walls, floors, ceilings, and partitions, significantly reducing structural load while maintaining strength and durability.

2. Core Composition & Structure

Core layer: Cement mixed with EPS beads, fly ash, and reinforcing fibers

Outer layer: Moisture-resistant fiber-cement boards (Cemboard)

Optional PVA fibers: Improve crack resistance, tensile strength, and lifespan

3. Available Types & Dimensions

Panel Type Standard Size (mm) Weight (kg/panel)

Hollow-core EPS panel 2440 × 610 × 100 ~105 kg

2-layer steel-reinforced 2440 × 610 × 75 / 100 84 – 105 kg

Solid-core 3-layer EPS 2440 × 610 × 75 / 100 84 – 100 kg

Other thickness options range from 20 mm to 100 mm depending on project requirements.

4. Key Technical Specifications

Average density: ~800–850 kg/m³

Thermal conductivity: < 0.025 W/m·K – excellent thermal insulation

Sound insulation: Up to 48 dB (with 100 mm thickness)

Fire resistance: Can withstand 1000°C for up to 3 hours

Water absorption: 7–8%, highly moisture-resistant

Load-bearing capacity: Up to 1000 kg/m² depending on type

5. Outstanding Advantages

Lightweight – Easier to handle and install, reduces construction time and labor

Thermal + sound insulation + fire resistance – Suitable for both residential and industrial projects

Highly durable – No warping, rotting, or corrosion

Eco-friendly – Low CO₂ emissions, made from recyclable materials

Flexible application – Easily cut and installed with basic tools

6. Practical Applications

Exterior and interior partition walls

Office dividers and cleanroom enclosures

Mezzanine floors and intermediate slabs

Ceilings and roof insulation

Boundary walls, prefab houses, temporary structures

EPS lightweight concrete panels are the ideal solution for construction projects that require fast installation, long-term energy efficiency, and cost savings.
