Rock Wool Strip

Rock Wool Strip | Flexible High-Temp Insulation for Gaps, Joints & Irregular Surfaces

Product Overview

Our Rock Wool Strip is a precision-cut insulation solution designed for challenging spaces requiring adaptable thermal and fire protection. Engineered from non-combustible basalt fibers, these flexible strips provide seamless coverage for gaps, joints, and complex geometries while maintaining Class A1 fire resistance and thermal stability up to 650°C (1200°F). Perfect for industrial equipment, HVAC systems, and architectural detailing, the strip format ensures easy installation in tight spaces without compromising performance.
