Fire Barrier Rock Wool lamella – 100kg/m³ / 120kg/m³ – Exterior Wall Insulation

Our fire barrier rock wool strips, available in 100kg/m³ and 120kg/m³ densities, are specially engineered for fire barriers in external wall insulation systems. Made from high-quality basalt and processed into strip form, they offer Class A1 non-combustibility, high tensile strength, and dimensional stability. With density options tailored to different building heights, load requirements, and fire safety demands, they effectively stop flame spread, providing reliable fire protection for high-rise buildings and public facilities.

• 100kg/m³ Rock Wool Strip: Ideal for fire barriers in standard-height buildings with standard load requirements—cost-effective and easy to install
• 120kg/m³ Rock Wool Strip: Suitable for high-rise and super-high-rise buildings with higher tensile strength demands—enhanced system safety
• Floor-by-floor fire stops for organic insulation materials (EPS, XPS, PU, etc.)
• Fire barriers around window and door openings
• Insulation systems near fire compartments and refuge floors

• Density-Graded Design for Various Project Needs
  100kg/m³: Lightweight and economical, ideal for general building fire barriers—easier handling and installation
  120kg/m³: Higher strength for high-rise buildings and demanding conditions—longer-lasting fire barrier performance
  Flexible selection based on project budget, building height, and load requirements ensures optimal balance between performance and cost.
• Class A1 Non-Combustible - Effectively Stops Flame Spread
  Meets Class A1 non-combustible material standard: does not burn, contribute to fire, or propagate flames. As a fire barrier for combustible insulation, it cuts off flame propagation paths and controls fire development.
• High Tensile Strength - Reliable System Safety
  High vertical tensile strength ensures secure bonding with the substrate—no falling, no hollowing over time—guaranteeing lasting and stable fire barrier performance under various working conditions.
• Fast and Easy Installation
  Uniform strip dimensions and precise cutting allow for quick installation with cement mortar on-site. Seamless integration with organic insulation boards significantly improves construction efficiency and reduces labor costs.
