| Sound Transmission Class (STC) | 45–55 | Walls and ceilings |
| Vibration Damping | Excellent | Reduces resonance in mechanical systems |
The composite facing adds rigidity and dimensional stability to the glass wool core, ensuring durability under mechanical stress, vibration, or compression.
| Property | Typical Value | Test Standard |
|---|---|---|
| Compressive Strength | 50–120 kPa | ASTM C165 |
| Density | 40–120 kg/m³ | GB/T 5480 |
| Tensile Strength | 15–25 kPa | ASTM C209 |

The Glass Wool Composite Insulation Board complies with multiple international and regional standards to ensure quality, safety, and environmental sustainability:
| Certification | Standard | Significance |
|---|---|---|
| CE Mark | EN 13501-1 | Fire safety compliance in Europe |
| ISO 9001 | Quality Management | Consistent manufacturing quality |
| RoHS | Restriction of Hazardous Substances | Safe for human health |
| REACH | Registration, Evaluation, Authorization, and Restriction of Chemicals | Environmental compliance |
| ASTM | ASTM C553, ASTM C518 | Thermal and mechanical performance verification |
To maximize the performance and lifespan of the board, follow these installation and handling precautions:
Protective Equipment: Always wear gloves, safety goggles, long sleeves, and a dust mask to prevent irritation from fine glass fibers.
Surface Preparation: Ensure installation surfaces are clean, dry, and free of dust, oil, or debris.
Avoid Moisture Exposure: Do not expose the board to water or prolonged high humidity to prevent degradation of thermal and mechanical properties.
Proper Cutting and Handling: Use a sharp utility knife or saw to cut the boards; avoid excessive force that can compress or damage the composite layers.
Avoid Direct Flame Contact: Although non-combustible, avoid exposing the board to open flames during installation.
Secure Installation: Fasten the board properly using mechanical fasteners or adhesive suitable for the substrate to avoid sagging or detachment.
Despite its robust design, improper handling or installation can lead to reduced performance. Below are common issues and recommended solutions:
| Fault | Cause | Solution |
|---|---|---|
| Sagging or deformation | Improper fastening or insufficient support | Reinstall using adequate mechanical fasteners; ensure correct overlap |
| Reduced thermal efficiency | Compressed fibers or water infiltration | Replace affected sections; maintain vapor barrier integrity |
| Moisture damage | High humidity or direct water exposure | Install vapor barriers; ensure proper ventilation |
| Noise transmission issues | Gaps between boards or poor fitting | Adjust and seal gaps with adhesive tape or sealant |
| Fire safety concern | Improper installation near heat sources | Maintain safe distance from open flames; follow fire code regulations |
| Tool/Material | Purpose |
|---|---|
| Measuring Tape | Accurate measurement of installation area |
| Utility Knife / Saw | Cutting boards to desired size |
| Protective Gear | Prevent irritation from fibers |
| Fasteners or Adhesive | Secure the board to walls, ceilings, or ducts |
| Vapor Barrier Film | Moisture control |
| Sealing Tape | Seal joints and edges |
Measure and Cut: Measure the area and cut boards slightly larger than required for a snug fit.
Place the Board: Position the board with the composite facing outwards; ensure tight fitting with overlapping joints where necessary.
Secure the Board: Use mechanical fasteners, adhesive, or wire mesh depending on the application.
Seal Edges and Joints: Apply tape or sealant to all seams to prevent air or moisture leakage.
Inspect Installation: Verify that the board is flat, properly supported, and free from damage.
| Task | Frequency | Method |
|---|---|---|
| Visual Inspection | Every 6 months | Check for sagging, gaps, or moisture damage |
| Cleaning | Annual | Use dry cloth or vacuum; avoid wet cleaning |
| Vapor Barrier Check | Annual | Ensure seals are intact |
| Replacement | As needed | Replace damaged or degraded boards |
Avoid compressing the board during maintenance.
Keep the environment well-ventilated to prevent condensation.
Replace sections promptly if water or mechanical damage occurs.
