200mm Height Fire Barrier Rock Wool Lamella – Exterior Wall Insulation
Our 200mm height fire barrier rock wool strip is specially engineered for exterior wall insulation systems, representing a thickened premium fire barrier solution that meets the stringent insulation thickness demands of passive houses and near-zero energy buildings.
As an enhanced fire barrier for combustible insulation systems, it provides extended flame penetration resistance, offering maximum fire protection for critical areas such as high-rise buildings, refuge floors, and fire compartments.
- Thickened fire barriers in passive house and near-zero energy building insulation systems
- Fire barriers around refuge floors in super-high-rise buildings
- Critical fire zones such as fire compartments and vertical fire breaks
- Exterior wall insulation in cold climate zones (requiring thicker insulation)
- Public buildings with special fire safety requirements (hospitals, schools, data centers, etc.)

Provides longer resistance to flame penetration, effectively delaying fire spread and buying crucial time for evacuation and firefighting.
Designed to meet the 250mm+ insulation thickness requirements common in passive buildings. This fire barrier can be installed in a single layer, eliminating the need for multi-layer buildup, reducing construction complexity, and minimizing system failure risks.
Meets Class A1 non-combustible material standard: does not burn, emit toxic fumes, or produce molten droplets. Provides absolute fire protection in critical areas such as refuge floors and fire compartments.
Excellent compressive strength and deformation resistance—no shrinkage, no collapse over time, ensuring lasting fire barrier performance.
Physical properties are well-matched with organic insulation layers (e.g., EPS, XPS), with similar thermal expansion coefficients, preventing stress cracking due to thickness differences and ensuring overall system stability.
