Product Description

Product Introduction

Expanded perlite is a versatile, lightweight material made from volcanic glass that expands when heated. It offers excellent thermal insulation, sound absorption, and fire resistance, making it ideal for use in building insulation systems. With its low density and high porosity, expanded perlite reduces energy consumption by effectively maintaining indoor temperatures, while also providing a durable and environmentally friendly solution for modern construction needs.

Applications

Exterior Insulation Finishing System (EIFS)
Flat and Pitched Roofs
Underfloor Insulation
Lightweight Concrete or Mortar
Fire Barriers
Soundproof Walls and Ceilings
Void Filling

Advantages

1. High Thermal Insulation Efficiency

• Low Thermal Conductivity: Expanded perlite has a low thermal conductivity (typically around 0.03-0.04 W/m·K) due to its porous structure, effectively reducing heat transfer. It is commonly used in insulation layers for roofs, walls, and floors, helping to maintain indoor temperatures and reduce energy consumption.

2. Lightweight Material

• Reduced Structural Load: Expanded perlite is extremely lightweight (with a density typically ranging from 30-150 kg/m³), which reduces the load on building structures when used as an insulation layer. This makes it particularly suitable for high-rise buildings and structures where weight reduction is critical.

3. Fire Resistance

• High-Temperature Endurance: As an inorganic material, expanded perlite can withstand high temperatures, with a melting point exceeding 1200°C. When used in buildings, it not only provides insulation but also acts as a fire-resistant barrier, slowing the spread of flames and enhancing the safety of the structure.

4. Sound Absorption

• Noise Reduction: The porous structure of expanded perlite is effective in absorbing sound waves and reducing noise transmission. When used in walls and floors, it helps improve indoor acoustics and minimizes external noise interference.

5. Moisture Resistance

• Stable Insulation in Damp Conditions: Although expanded perlite can absorb some moisture, it has good moisture resistance and can maintain its insulation properties in damp environments. This makes it widely used in external wall insulation systems and underground structures.

6. Environmental and Sustainability Benefits

• Non-Toxic and Harmless: Expanded perlite is made from natural volcanic glass and does not release harmful substances during use. It is environmentally friendly, aligning with modern building requirements for sustainable materials.
