EPS Cement Sandwich Panel is an innovative, lightweight composite prefabricated building material widely used in modern construction.
一、Basic Structure
- Outer Layers: Made of calcium silicate board or fiber cement board, providing structural strength and surface durability.
- Core Layer: Composed of EPS (expanded polystyrene) beads mixed with cement, sand and other additives, formed through a one-step compound process.
- Overall Feature: It follows the classic sandwich composite structure, which optimizes the load-bearing performance while keeping the overall weight very low.
二、Core Advantages
- Lightweight: Its volume weight is only 750-800kg/m³, and a 75mm-thick panel weighs about 1/6 of the traditional brick wall of the same area.
- High Fire Resistance: It can reach Class A1 non-combustible rating, the highest fire safety standard for building materials, avoiding the flammable defect of pure EPS foam boards.
- Multi-functional Performance: It integrates thermal insulation, sound insulation, waterproofing and seismic performance, and can effectively reduce the overall cost of construction projects.
- High Construction Efficiency: Most products are designed with tongue-and-groove interlocking structure, which can greatly shorten the on-site construction period.
三、Main Application Scenarios
It is widely used in residential apartments, commercial offices, hospitals, schools, prefabricated buildings, warehouses and other building scenarios, and can be used as exterior walls, interior partition walls, roof panels and other components.
