How to fireproof and seal cable trays in vertical shafts

Fireproof cable trays in vertical shafts are sealed using a combination of fire-rated rock wool panels, intumescent sealants, fire pillows, and fire mortar to ensure airtight, fire-resistant compartmentation.

Key Materials

Fire Batts (Fire-Rated Rock Wool Panels): High-density slabs cut to fit around cables, filling all gaps. Small remaining gaps are sealed with intumescent sealant, which swells under heat to maintain fire integrity. Fire Pillows: Flexible, removable bags filled with intumescent graphite, ideal for areas where cables are frequently added or removed.

They can be repositioned without breaking the seal. Fire Mortar: Special fire-rated powder mixed with water and applied around cables in vertical shafts. Once dry, it behaves like concrete and contains intumescent powder that swells to seal cracks.

Firestop Mastic and Putty: Used to seal smaller gaps around metal trays or conduit penetrations, ensuring complete coverage and adherence to surfaces.

Installation Process

Prepare the Shaft: Ensure floor and wall finishes are complete, and shaft doors are installed. Large openings may require a fire-resistant backing plate before sealing. Position Cable Trays: Install trays and route cables according to design, leaving appropriate gaps for fireproofing materials.

Apply Fire Batts or Fire Pillows: Cut fire batts to fit tightly around cables, filling all voids. For removable solutions, stack fire pillows around and between cables. Seal Remaining Gaps: Use intumescent sealant or firestop mastic to fill any small gaps (
