ArmaProtect™ CB
ArmaProtect™ CB is a high-density mineral wool firestop board pre-coated with an ablative fire protection coating. Engineered to maintain compartmentation in fire-rated walls and floors, this coated board system provides reliable, code-compliant sealing for medium to large mixed-service penetrations and blank openings in commercial, industrial, and residential structures.
Used in conjunction with ArmaProtect™ ABLC coating and ArmaProtect™ ABLF filler mastic, the board creates an airtight, smoke-tight barrier that absorbs thermal energy in a fire, preventing flame spread and toxic gas transmission.
Key Features & Benefits
- High Fire Rating: Tested and certified to achieve fire resistance ratings up to EI 240 (European Technical Assessments under EN 1366-3) and UL-listed FT-Ratings up to 3 hours (ANSI/UL 1479 / ASTM E814).
- Versatile Penetration Sealing: Suitable for blank openings and complex mixed services, including single/bundled cables, cable trays, conduits, non-combustible pipes, and combustible piping.
- Weather & Environmental Resistance: Tested to Use Category Type X (EOTA TR 024), ensuring durability in conditions exposed to atmospheric weathering, frost, and ambient humidity swings.
- Safe & Low-VOC: Halogen-free, solvent-free, and compliant with Green Seal GS-11 standards (< 50g/l VOC) for safe indoor installation.
- Easy Cut & Custom Fit: Pre-coated mineral wool boards are lightweight, easy to handle, and simple to cut to size on-site for seamless installation around intricate utility configurations.
