Product Specification

RG Thermial insulation Calcium Silicate Boards in High Performance

Product Overview

RG Calcium silicate board is an advanced inorganic insulation material manufactured through a hydrothermal reaction of silica, calcium oxide, and reinforcing fibers. The resulting microporous structure creates a lightweight, rigid board with exceptional thermal, fire, and moisture-resistant properties, making it one of the most versatile insulation solutions across construction and industrial applications.

Core Characteristics & Advantages

1. Exceptional Fire Performance

• Non-combustible (A1/A2 Fire Rating): Will not ignite, contribute to fire spread, or produce significant smoke

• High Temperature Resistance: Continuous service up to 650°C (1200°F) for standard grades, with high-temperature variants exceeding 1000°C (1832°F)

• Fire Protection Systems: Maintains structural integrity during fire exposure, protecting structural elements and creating effective fire barriers

• Zero Fire Toxicity: Emits no toxic fumes when exposed to flame

2. Superior Thermal Insulation

• Low Thermal Conductivity: Typically 0.05–0.06 W/m·K at 20°C

• Energy Efficiency: Significantly reduces heat transfer in both high-temperature and building envelope applications

• Dimensional Stability: Maintains insulating properties and shape across wide temperature ranges

3. Moisture & Chemical Resistance

• Hydrophobic Properties: Naturally moisture-resistant with optional silicone treatments for enhanced performance

• Mold & Mildew Resistance: Inorganic composition prevents biological growth

• Chemical Inertness: Resistant to most oils, solvents, and mild acids/alkalis

• Low Water Absorption: Typically <5% by volume (with treated versions <2%)

4. Mechanical & Physical Properties

• High Strength-to-Weight Ratio: Rigid structure with densities ranging from 170–1000 kg/m³

• Workability: Easily cut, shaped, and machined with standard woodworking tools

• Good Dimensional Stability: Low thermal expansion and minimal shrinkage

• Excellent Surface: Suitable for direct finishing or cladding

Product Classification & Grades

By Density & Application

1. Low-Density (170–350 kg/m³): Primarily for building insulation, ceilings, and wall systems

2. Medium-Density (350–700 kg/m³): General industrial insulation, fire protection, partitions

3. High-Density (700–1000+ kg/m³): Structural applications, high-temperature industrial use, load-bearing elements

By Function & Specialization

• Standard Building Boards: For interior partitions, ceilings, wall lining

• Fire-Rated Boards: Enhanced formulations for fire doors, shafts, protection systems

• Industrial Insulation Boards: For pipes, vessels, boilers, and equipment

• Exterior Grade: Weather-resistant with improved moisture performance

• Acoustic Boards: Enhanced sound absorption properties

Installation & Fabrication

Working Methods

• Cutting: Easily cut with hand saws, scoring knives, or power tools

• Machining: Can be routed, drilled, and shaped with standard equipment

• Fastening: Accepts screws, nails, and adhesives suitable for mineral substrates

• Joining: Boards can be butted tightly; joints may be taped, filled, or caulked

• Finishing: Can be painted, plastered, tiled, or left exposed

Installation Considerations

• Substrate Preparation: Ensure clean, dry, and even surfaces

• Mechanical Fixing: Use corrosion-resistant fasteners appropriate for the substrate

• Expansion Joints: Allow for thermal movement in large installations

• Moisture Protection: Seal edges and joints in high-humidity environments

• Safety: Use appropriate dust control and personal protective equipment during cutting
