FAQ

Q: What is the fire rating of this panel?
A: The panel core is made of rockwool, achieving A2 class fire resistance (non-combustible) according to EN 13501-1. This means it does not contribute to fire development and is suitable for high-safety buildings.
Q: Can the panel be used for interior walls as well?
A: Yes, while designed for exterior walls, it can also be used for interior partitions, ceilings, and cold storage rooms where fire resistance and insulation are required.
Q: What thicknesses are available?
A: Standard thickness is 50mm, but we also offer 30mm, 40mm, 60mm, 80mm, 100mm, and 120mm options upon request. Custom thicknesses are available for bulk orders.
Q: How long does the panel last?
A: With proper installation and maintenance, the panel can last 20–30 years. The metal facings are coated to resist corrosion, and the rockwool core does not degrade over time.
Q: Do you provide sample panels?
A: Yes, we can supply small samples (e.g., 300mm x 300mm) for quality evaluation. Please contact your sales representative for sample request and shipping details.
Q: What is the load-bearing capacity of a 50mm panel?
A: The load capacity depends on the facing thickness and span. For a standard 0.5mm steel facing, typical load capacity is around 0.5 kN/m². For higher loads, thicker facings or additional supports can be designed.
Q: Are the panels recyclable?
A: Yes, the metal facings are fully recyclable, and rockwool can be reused or recycled as part of mineral wool waste management. The panels contribute to sustainable building practices.
Q: Can I get the panel in a custom color?
A: Absolutely. We offer RAL colors and custom color matching. The surface can be coated with PVDF, polyester, or other finishes for enhanced weather resistance and aesthetic appeal.
