Expanded Perlite Lightweight Panel

Updated: 2026-08-03

Overview

Lightweight Expanded Shale Panel is a modern construction material made from expanded shale aggregate, cement, and additives. It is designed to provide a lightweight yet durable solution for various building applications. The panel is known for its excellent thermal insulation properties, fire resistance, and ease of installation. The material is particularly popular in prefabricated construction and modular building projects due to its versatility and environmental benefits. Expanded shale, the primary component, is a sustainable material that reduces the overall carbon footprint of construction projects.

Structure and Working Principle

The panel consists of a core made from expanded shale aggregate, which is lightweight and porous, providing thermal and acoustic insulation. The outer layers are typically reinforced with cement or other binding materials to enhance structural integrity. When used in construction, the panels are installed as partitions or ceilings, where their lightweight nature reduces the load on the building framework. The porous structure of expanded shale also helps in regulating temperature and moisture, contributing to energy efficiency.

Key Features

Lightweight Expanded Shale Panels offer several advantages, including high fire resistance, making them suitable for fire-rated assemblies. They are also thermally insulating, reducing energy costs for heating and cooling. Additionally, the panels are eco-friendly, as expanded shale is a natural and recyclable material. Their lightweight nature simplifies transportation and installation, reducing labor costs and construction time.

Application Areas

These panels are widely used in commercial, industrial, and residential construction for partitions, ceilings, and prefabricated structures. They are also employed in renovation projects where lightweight and insulating materials are required. In addition to building applications, the panels are used in soundproofing and thermal insulation systems, making them a versatile choice for architects and builders.

Maintenance and Precautions

Lightweight Expanded Shale Panels require minimal maintenance once installed. However, they should be handled carefully during transportation and installation to prevent chipping or cracking. Storage should be in a dry environment to avoid moisture absorption, which could affect the panel's performance. Regular inspections for cracks or damage are recommended to ensure long-term durability.

B2B Procurement Guide

When procuring Lightweight Expanded Shale Panels, consider the panel's thickness, load-bearing capacity, and fire rating to match project specifications. It's advisable to request samples and technical data sheets from suppliers to verify quality. Prices vary based on thickness and customization, with standard panels typically costing between $15 and $30 per square meter. Bulk purchases may qualify for discounts, so negotiate with suppliers for large orders.
