Rock wool sandwich panels are known for their good resistance to moisture and certain environmental factors. These panels typically have high resistance to moisture absorption, making them suitable for use in environments where humidity or moisture levels are a concern. Rock wool itself is a hydrophobic material, meaning it repels water and resists moisture penetration.

In terms of corrosion resistance, rock wool itself is non-corrosive. However, the panels may contain other materials, such as metal sheets or structures, which might be subject to corrosion. The resistance to corrosion would depend on the specific components and coatings used in the panel's construction.

Regarding other environmental factors, rock wool panels generally offer good resistance to fire, high temperatures, and can provide thermal and acoustic insulation. They are durable and can withstand various environmental conditions.

It's important to note that while Rock wool sandwich panels offer resistance to moisture and certain environmental elements, the specific properties and durability may vary depending on the quality, manufacturing process, and additional protective layers or coatings applied to the panels.
