While rock wool sandwich panels are durable and require minimal maintenance compared to some other building materials, there are still some recommended maintenance tasks and inspections to ensure their continued effectiveness over time. 

Regular Inspections: Periodic visual inspections of the rock wool sandwich panels should be conducted to check for any signs of damage, such as cracks, dents, or moisture infiltration. Inspections should be carried out both internally and externally, including walls, roofs, and ceilings.

Sealant Inspection: If the panels are installed with sealants or jointing materials, these should be inspected for signs of deterioration or failure. Any gaps or breaches in the seals should be promptly repaired to maintain the integrity of the insulation system.

Moisture Management: Ensure that the panels remain free from moisture accumulation, as prolonged exposure to moisture can degrade the insulation properties of rock wool. This includes regular inspection of drainage systems, gutters, and downspouts to prevent water from pooling or infiltrating the panels.

Cleaning: Clean the panels periodically to remove dirt, debris, or pollutants that may accumulate on the surface. This can be done using mild detergent solutions and water, followed by rinsing with clean water. Avoid using abrasive cleaners or high-pressure washing, as these can damage the panels.

Pest Control: Inspect the panels for any signs of pest infestation, such as insects or rodents, and take appropriate measures to control or prevent further damage. Sealing any entry points and maintaining a clean environment around the building can help deter pests.

Repairs: Address any damage or defects in the rock wool sandwich panels promptly to prevent further deterioration. This may involve patching or replacing damaged sections of the panels, repairing seals or joints, or applying protective coatings as needed.

Documentation: Keep records of maintenance activities, inspections, and repairs performed on the rock wool sandwich panels. This documentation can help track the condition of the panels over time and identify any recurring issues that may require attention.
