Width of fireproof board for cable tray sealing

The width of fireproof boards for cable tray sealing should match the tray width plus 1/2 inch (13 mm) on each side for the bottom, with top boards including the bottom width plus two board thicknesses.

Board Width Guidelines

Bottom Boards: Cut to the width of the tray including connecting bolts, plus 1/2 inch (13 mm) on each side to ensure full coverage and proper sealing. Top Boards: Cut to the width of the bottom piece plus two board thicknesses, allowing for overlap and secure fireproofing. Attachment Strips: Should be at least 3 inches (76 mm) wide and span the tray width, providing support for butt joints and ensuring the boards remain tightly secured.

Installation Considerations

Side Boards: Cut to the height of the tray plus three board thicknesses, plus 1/2 inch (13 mm) to accommodate the tray height and allow for proper sealing. Attachment: Use metal banding and retaining clamps to secure strips at the top and bottom of the tray. Position attachment strips approximately 24 inches (610 mm) on centers for consistent support.

Overlap: Bottom attachment strips should overlap each bottom piece of the butt joint by at least 1 1/2 inches (38 mm) to maintain fire integrity.

Additional Notes

Ensure that all gaps between boards and around cables are sealed tightly to prevent fire and smoke penetration. For larger openings or unusual tray styles, consult manufacturer guidelines or engineering judgment letters to confirm proper board sizing and firestop compliance. Fireproof boards may be combined with intumescent sheets, caulks, or mineral wool for enhanced fire resistance, depending on the system requirements.

By following these width and installation guidelines, fireproof boards will effectively seal cable trays, maintain fire rating integrity, and comply with safety standards.
