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
