Industrial High-Strength Glass Wool: Advanced Thermal and Acoustic Insulation for Industrial Applications
Industrial High-Strength Glass Wool is a premium insulation material specifically engineered for high-demand industrial environments such as power plants, refineries, chemical factories, and heavy machinery installations. Its unique composition of high-density glass fibers combined with thermosetting resin provides superior mechanical strength, excellent thermal insulation, and sound absorption.
This material is ideal for applications that require long-term durability, fire resistance, and energy efficiency. Its lightweight yet robust structure ensures easy handling and installation, making it a preferred solution for industrial projects worldwide.
The Industrial High-Strength Glass Wool delivers a combination of properties tailored for challenging industrial conditions.
The densely packed glass fibers reduce heat transfer, helping maintain stable temperatures in industrial facilities. This improves energy efficiency, lowers operational costs, and protects sensitive equipment from thermal fluctuations.

| Thermal Conductivity | 0.032–0.040 W/m·K | Minimizes heat loss and energy consumption |
| Service Temperature | -120°C to +450°C | Suitable for high-temperature industrial equipment |
| Heat Retention | Excellent | Reduces need for additional heating or cooling |
Industrial glass wool is non-combustible, meeting international Class A fire standards. It does not emit toxic gases when exposed to flames, offering enhanced safety for personnel and infrastructure.
| Feature | Value | Standard |
|---|---|---|
| Fire Rating | A1 (Non-combustible) | EN 13501-1 |
| Smoke Production | Minimal | ISO 5659 |
| Flame Spread | Zero | ASTM E84 |
The porous structure of glass wool efficiently absorbs sound waves, reducing noise in industrial environments. Its Noise Reduction Coefficient (NRC) typically ranges from 0.75 to 0.95, making it suitable for machinery rooms, refineries, and production floors where noise control is critical.
Industrial high-strength glass wool is designed to withstand mechanical stress, vibration, and compression, ensuring long-term dimensional stability. This makes it ideal for industrial ducts, pipes, and heavy-duty machinery insulation.
| Property | Typical Value | Test Standard |
|---|---|---|
| Compressive Strength | 50–120 kPa | ASTM C165 |
| Density | 48–120 kg/m³ | GB/T 5480 |
| Tensile Strength | 15–25 kPa | ASTM C209 |

To ensure reliability and consistent performance, each batch of industrial glass wool undergoes rigorous quality testing and inspection.
| Test Type | Standard | Purpose |
|---|---|---|
| Thermal Conductivity | ASTM C518 | Measures insulation efficiency |
| Fire Resistance | EN 13501-1 | Determines combustibility |
| Water Absorption | ASTM C1104 | Evaluates moisture resistance |
| Density & Compression Strength | GB/T 5480 | Ensures structural stability |
| Sound Absorption | ISO 354 | Confirms acoustic performance |
Raw Material Inspection: Ensures purity of glass fibers and resin consistency.
Production Monitoring: Controls fiber diameter, density, and curing process.
Post-Production Testing: Verifies thermal, mechanical, and acoustic properties.
Final Product Audit: Random batch sampling for dimensional accuracy, weight, and moisture content.
All reports are documented and certified, allowing clients to verify performance standards before project implementation.
Proper installation is critical to ensure the performance and longevity of industrial high-strength glass wool.
| Tool/Material | Purpose |
|---|---|
| Measuring Tape | Accurate measurement of installation area |
| Utility Knife or Saw | Cutting insulation to required dimensions |
| Protective Gear (Gloves, Mask, Goggles) | Safety during handling |
| Mechanical Fasteners | Securing insulation to pipes, ducts, or panels |
| Vapor Barrier | Prevents moisture accumulation |
| Adhesive Tape | Sealing joints and overlaps |
Surface Preparation: Clean the installation surface, removing dust, oil, and debris.
Measurement and Cutting: Cut the glass wool to slightly larger dimensions for snug fitting.
Placement: Roll or place the insulation along pipes, ducts, or wall panels. Overlap seams by at least 50 mm.
Fixing: Secure using wire mesh, fasteners, or adhesive, depending on application type.
Vapor Barrier and Sealing: Apply barrier and tape joints to prevent moisture ingress.
Inspection: Verify all sections are properly fitted, with no gaps or compression.
Regular maintenance ensures that thermal and acoustic performance remains consistent over time.
| Task | Frequency | Method |
|---|---|---|
| Visual Inspection | Every 6 months | Check for sagging, moisture, or mechanical damage |
| Cleaning | Annual | Dry cleaning or vacuum; avoid harsh chemicals |
| Vapor Barrier Check | Annual | Ensure seams and edges remain sealed |
| Performance Testing | Every 2–3 years | Thermal and acoustic verification |
