Chapter 1
What is Glass Wool Board ?
Rigid insulation designed for energy efficiency, soundproofing, and fire protection
Glass Wool Board is a high-density insulation panel made from fine glass fibers bonded with resin. It offers excellent thermal insulation, sound absorption, and fire resistance. Commonly used in walls, ceilings, HVAC ducts, and fire-rated enclosures, it helps reduce energy consumption and enhance indoor comfort. Available in various thicknesses and facings like aluminum foil or glass cloth, Glass Wool Board is lightweight, easy to install, and environmentally friendly. Its non-combustible nature (Class A1 fire rating) and compliance with international standards make it ideal for commercial, industrial, and residential projects seeking high-performance and durable insulation solutions.

Features of Glass Wool Board
Built-in performance for modern thermal, acoustic, and fire-rated construction needs
- Low Thermal Conductivity:Effectively minimizes heat transfer, reducing energy bills in both hot and cold climates.
- Superior Acoustic Performance: Absorbs and dampens airborne sound, perfect for interior partition walls and ceilings.
- Fireproof Composition:Class A1 non-combustible — does not ignite, melt, or emit toxic gases during fires.
- Water-Resistant Options:Faced boards with aluminum foil or glass cloth prevent moisture buildup and fiber degradation.
- High Mechanical Strength:Rigid enough for installation behind panels or above ceilings without sagging or collapse.
- Eco-Friendly & Sustainable:Contains up to 80% recycled content; formaldehyde-free options available.

Quality Assurance for Glass Wool Board
Henan Jianhong Refractory strictly adheres to ISO 9001 quality standards, utilizing advanced testing equipment for comprehensive inspections. Every batch of our Glass Wool Board undergoes rigorous testing, ensuring it meets global quality benchmarks and your exacting requirements for reliability, durability, and performance.
The key quality tests typically include:
| Core Inspection Items | Inspection Content & Requirements | Reference Standards | Inspection Methods |
|---|---|---|---|
| Surface Quality & Integrity | No damage, holes, severe agglomeration/linting; uniform fiber distribution. Boards/blankets: No severe edge chipping. Pipe sections: Flat ends, no cracks. | GB/T 13350 Thermal Insulation Products—Glass Wool and Its Products | Visual inspection under natural light; manual touch for flatness. (Optional: Ruler check for edge chipping ≤5mm). |
| Key Dimensional Accuracy | Thickness deviation ≤±5% (boards/blankets/pipe sections). Length/width deviation ≤±5mm (boards/blankets). ≤0.044 W/(m·K) at 70℃ (general); ≤0.040 W/(m·K) at 25℃ (high-precision). | GB/T 13350 | Measure with steel ruler/caliper. (Thickness: Use thickness gauge with 2kPa±0.5kPa pressure; average from multi-points). |
| Thermal Conductivity (70℃/25℃) | ≤0.044 W/(m·K) at 70℃ (general); ≤0.040 W/(m·K) at 25℃ (high-precision). Directly determines thermal insulation efficiency. | GB/T 10294 (Heat Flow Meter Method) GB/T 10295 (Guarded Hot Plate Method) | Heat Flow Meter (routine rapid test)or Guarded Hot Plate Method (high-precision calibration, simulating actual service temperature). |
| Bulk Density | Matches nominal value (typical range: 10–96 kg/m³; e.g., 24–48 kg/m³ for boards). Affects strength and insulation synergy. | GB/T 13350 | Cut regular samples (≥100mm×100mm×nominal thickness).Weigh with electronic balance (0.1g precision); calculate density from volume. |
| Average Fiber Diameter | ≤8μm (Overly thick fibers reduce insulation; overly thin fibers cause linting).Ensures structural and insulation synergy. | GB/T 5480.4 Test Methods for Fiber Diameter of Mineral Wool and Its Products | Optical microscope (≥400× magnification).Randomly measure 100 fibers; calculate average. |
| Tensile Strength (Longitudinal/Vertical) | Boards: Vertical strength ≥10 kPa. Blankets: Longitudinal strength ≥5 kPa. Prevents cracking during installation/use. | GB/T 13350 | Universal testing machine (sample: 150mm×50mm; speed: 50mm/min).Calculate strength from breaking load. |
| Combustion Performance Rating | Must reach Non-combustible Class A1 (core building insulation requirement per GB 8624). Flame spread and smoke production meet limits. | GB 8624 Classification for Combustion Performance of Building Materials and Products GB/T 5464 Test Methods for Non-Combustibility of Building Materials | Cone calorimeter (full-size samples) or non-combustibility test (for Class A1).Classify by heat release, smoke density, etc. |
| Formaldehyde Emission | ≤0.1mg/m³ (meets indoor environmental safety per GB 18580). Avoids decoration pollution. | GB 18580 Limit of Formaldehyde Emission of Wood-based Panels and Finished Products for Indoor Decoration | Environmental test chamber (volume ≥1m³; temperature 23℃±1℃). Detect with gas chromatography. |
| Asbestos Content | Asbestos-free (content <0.1%; mandatory compliance). Eliminates health hazards. | GB/T 23263 Test Methods for Asbestos Content in Asbestos Products | Polarized light microscopy (qualitative) + X-ray diffraction (quantitative). Analyze fiber morphology and composition. |
Through this meticulous testing process, we ensure that our Glass Wool Board products meet the highest standards of quality, reliability, and performance, making them ideal for various applications in various industries.
