The recommended maintenance cycle for thermal insulation materials is a comprehensive inspection at least once a year. In harsh environments or industrial settings, this should be shortened to once every six months. Regular maintenance effectively extends their service life and ensures thermal insulation performance.
Maintenance Cycle and Key Measures
Routine Inspection: Conduct a visual inspection after each rainy season or extreme weather event to check for cracks, hollow areas, water seepage, or peeling.
Moisture Content Testing: For highly hygroscopic materials such as glass wool and rock wool, it is recommended to test the moisture content annually to prevent a decrease in thermal resistance due to dampness.
Infrared Thermal Imager Scanning: Use infrared equipment every 1–2 years to detect weak points and thermal bridges in the insulation layer to promptly identify hidden problems.
Protective Layer Maintenance: Recoat the finishing paint every 5–10 years to enhance weather resistance; regularly inspect the coating of metal protective panels for corrosion.
Local Repair: Repair small areas of damage immediately with matching materials to prevent the problem from worsening.
Key practices for extending lifespan:
Drilling or grooving in the insulation layer is strictly prohibited to avoid damaging structural integrity.
Add a moisture barrier in damp areas such as basements and near pipes.
Clean the surface regularly, but never use a high-pressure water gun to prevent coating damage.
Seale pipe penetrations and joints tightly to prevent condensation from forming thermal bridges.
