Composite Silicate Insulation Board

Updated: 2026-07-16

Overview

Composite silicate insulation board is a lightweight, high-performance thermal insulation material primarily composed of silicate compounds. It is widely used in industrial and construction sectors due to its excellent heat resistance and energy-saving properties. The material is manufactured through a specialized process that ensures uniform density and structural integrity. Its versatility makes it suitable for various high-temperature applications, including industrial furnaces, boilers, and pipelines. The board is also favored in building insulation for its fireproof and eco-friendly characteristics.

Physical and Chemical Properties

Composite silicate insulation board exhibits low thermal conductivity, typically ranging from 0.035 to 0.065 W/(m·K), making it highly effective for heat retention. The material is lightweight, with a density of approximately 150-300 kg/m³, and offers excellent fire resistance, withstanding temperatures up to 1000°C. Chemically, it is stable and resistant to corrosion, acids, and alkalis. The board is also hydrophobic, preventing moisture absorption and maintaining insulation performance over time. Its solid structure ensures durability and long-term usability in harsh environments.

Main Applications

The primary use of composite silicate insulation board is in industrial settings, such as insulation for furnaces, boilers, and pipelines in petrochemical, power, and metallurgical industries. Its ability to withstand high temperatures and reduce heat loss makes it indispensable for energy-efficient operations. In construction, it is applied in wall and roof insulation for commercial and residential buildings. The material’s fireproof properties enhance safety, while its lightweight nature simplifies installation. Additionally, it is used in HVAC systems and refrigeration units to improve thermal efficiency.

Safety and Storage

Composite silicate insulation board is non-toxic and safe to handle, but precautions should be taken to avoid dust inhalation during cutting or installation. Workers should wear protective masks and gloves to minimize exposure. Storage requires a dry, ventilated environment to prevent moisture absorption, which could compromise insulation performance. The boards should be stacked flat and protected from heavy loads to avoid deformation. Proper handling ensures the material retains its properties and extends its service life.

B2B Procurement Guide

When procuring composite silicate insulation boards, prioritize suppliers with certifications for quality and fire safety standards, such as ISO and ASTM. Request product samples to verify thermal conductivity and density specifications. Bulk purchases often attract discounts, but ensure storage facilities meet requirements to prevent damage. Compare prices from multiple vendors, keeping in mind that higher-quality boards may offer long-term cost savings through better performance and durability. Lead times and logistics should also be factored into procurement planning.
