The maintenance of glass wool boards focuses on moisture protection, structural integrity checks, and environmental control, with the primary goal of ensuring stable, long-term thermal insulation and sound absorption performance.
First, moisture and water protection are crucial. Although glass wool is inherently resistant to corrosion, prolonged exposure to moisture allows water to fill its internal air voids, significantly reducing its thermal insulation efficiency. Therefore, when used in roofing, exterior walls, or piping systems, the outer protective layer (such as aluminum foil, fiberglass cloth, or a moisture barrier) must remain intact to prevent the infiltration of rainwater or condensation.
Regular inspections of structural integrity are also required. Attention should be paid to issues such as sagging, detachment, cracking, or loose joints; fasteners are particularly prone to loosening in areas like suspended ceilings or locations subject to significant equipment vibration. Any damage detected should be repaired or the affected sections replaced promptly to avoid compromising the system's overall performance.
During equipment maintenance or building renovations, care should be taken to avoid damaging the installed glass wool boards. If removal is necessary, proper procedures and protective measures must be followed to prevent fiber dispersion and contamination. Upon reinstallation, the original sealing and fastening configurations must be restored to ensure that thermal insulation and sound absorption capabilities are not compromised. Implementing these routine maintenance measures effectively extends the service life of the glass wool boards and maintains their performance stability.
