Roof Mineral Wool Board – Frequently Asked Questions
Roof mineral wool board is a rigid, non-combustible insulation board designed specifically for flat roof and inverted roof systems. According to Wikipedia, mineral wool products are widely used in construction for their outstanding fire resistance, thermal insulation, and acoustic absorption properties.
Roof mineral wool board is a high-density, rigid insulation board manufactured from stone or rock wool fibres bonded with thermosetting resin. Its high compressive strength (≥40–80 KPa at 10% deformation) prevents settlement under roofing loads. Unlike softer insulation, roof mineral wool board maintains its thickness and R-value permanently, ensuring long-term thermal performance in flat and inverted roof systems.
EcoIn roof mineral wool board is available in four density grades: RB40, RB50, RB60, and RB80 (nominal densities of 40, 50, 60, and 80 kg/m³). Compressive strength ranges from ≥40 KPa (RB40) to ≥80 KPa (RB80) at 10% deformation per EN826. Higher-density grades are recommended for trafficked roofs and green roof assemblies.
EcoIn roof mineral wool board achieves a Class A1 Euroclass non-combustible fire reaction rating. It complies with EN826 and BS2972 for compressive strength, EN12430 for point load resistance, and GB ISO1182 / GB/T 5464-1999 for fire performance. The boards are suitable for use in roof assemblies subject to building regulations requiring non-combustible insulation above deck.
Standard roof mineral wool board dimensions are 1200×600 mm and 1000×500 mm, with thickness options from 30 mm to 200 mm. EcoIn can supply custom board sizes and thickness combinations to match project-specific specifications. Other sizes are available upon request with a minimum order quantity.
Standard roof mineral wool board orders from EcoIn are dispatched within 7–15 working days from order confirmation. Boards are palletised and shrink-wrapped for safe transit. Payment terms are T/T bank transfer or L/C at sight for international orders. Contact EcoIn for volume pricing and freight quotations.
