150mm Height Fire Barrier Rock Wool Lamella – Exterior Wall Insulation

Product Overview

Our 150mm height fire barrier rock wool strip is specially engineered as a fire barrier for external wall insulation systems, offering the optimal balance between performance and cost. Made from high-quality basalt through advanced processing, this product features a 150mm height that meets most building code requirements for fire barriers while avoiding over-engineering and material waste.

As a standard-grade fire barrier for combustible insulation systems, it effectively blocks flame spread, providing cost-effective fire protection for high-rise residential buildings, commercial complexes, and public facilities.

Applications

Standard fire barriers in exterior wall insulation systems for residential and commercial buildings
Conventional floor-by-floor fire stops for organic insulation materials (EPS, XPS, PU, etc.)
Fire barriers around window and door openings
Fire barriers for medium-thickness insulation layers
Exterior wall insulation in hot summer and cold winter regions
Projects with fire safety requirements but budget constraints

150mm Height Fire Barrier Rock Wool Lamella – Exterior Wall Insulation

Key Features & Advantages

150mm Height – Meets Mainstream Project Needs

The most widely adopted fire barrier in ETICS projects, no need for special customization and short lead times.

Class A1 Non-Combustible – Reliable Fire Safety

Meets Class A1 non-combustible material standard: does not burn, emit toxic fumes, or produce molten droplets. As a standard fire barrier, it effectively cuts off flame propagation paths and controls fire development.

Easier Installation

Easy on-site handling, cutting, and bonding, requiring less specialized labor and significantly reducing construction time and costs.

Perfect Compatibility with Standard Insulation Systems

Physical properties are well-matched with commonly used organic insulation thicknesses (e.g., EPS, XPS), with similar thermal expansion coefficients, preventing system stress and ensuring overall stability.
