These panels are widely used for the roofing and wall cladding of steel-structure industrial buildings and modular structures, as well as for ceilings and partitions in cleanrooms. Rock wool sandwich panels can generally be customized to meet specific client requirements. They are primarily utilized across a diverse range of sectors-including automotive and parts manufacturing, aerospace, machinery, coal, steel and metallurgy, warehousing and logistics, power generation and energy, electronics and photovoltaics, food and beverage, pharmaceuticals, and tobacco-as well as in applications that require moisture resistance, thermal insulation, fire protection, and sound absorption.
In terms of fire safety, rock wool sandwich panels are flame-retardant and classified as Class A non-combustible materials, providing effective fire protection for buildings. Fire testing has demonstrated that when exposed to an open flame, rock wool only chars on the surface and self-extinguishes once the flame is removed. In cigarette-smoldering tests, the material exhibits only smoldering combustion with no significant changes after the heat source is taken away; in simulations of electrical short circuits, the rock wool shows only minor charring. Compared to materials such as polyurethane foam sandwich panels, rock wool sandwich panels offer distinct advantages in terms of heat resistance and fire containment.
