REACHRegistration, Evaluation, Authorization, and Restriction of ChemicalsEnvironmental compliance
ASTMASTM C553, ASTM C518Thermal and mechanical performance verification

3. Usage Precautions

To maximize the performance and lifespan of the board, follow these installation and handling precautions:

  1. Protective Equipment: Always wear gloves, safety goggles, long sleeves, and a dust mask to prevent irritation from fine glass fibers.

  2. Surface Preparation: Ensure installation surfaces are clean, dry, and free of dust, oil, or debris.

  3. Avoid Moisture Exposure: Do not expose the board to water or prolonged high humidity to prevent degradation of thermal and mechanical properties.

  4. 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.

  5. Avoid Direct Flame Contact: Although non-combustible, avoid exposing the board to open flames during installation.

  6. Secure Installation: Fasten the board properly using mechanical fasteners or adhesive suitable for the substrate to avoid sagging or detachment.


4. Common Fault Causes and Solutions

Despite its robust design, improper handling or installation can lead to reduced performance. Below are common issues and recommended solutions:

FaultCauseSolution
Sagging or deformationImproper fastening or insufficient supportReinstall using adequate mechanical fasteners; ensure correct overlap
Reduced thermal efficiencyCompressed fibers or water infiltrationReplace affected sections; maintain vapor barrier integrity
Moisture damageHigh humidity or direct water exposureInstall vapor barriers; ensure proper ventilation
Noise transmission issuesGaps between boards or poor fittingAdjust and seal gaps with adhesive tape or sealant
Fire safety concernImproper installation near heat sourcesMaintain safe distance from open flames; follow fire code regulations

5. Installation Instructions

5.1 Required Tools and Materials

Tool/MaterialPurpose
Measuring TapeAccurate measurement of installation area
Utility Knife / SawCutting boards to desired size
Protective GearPrevent irritation from fibers
Fasteners or AdhesiveSecure the board to walls, ceilings, or ducts
