Product catalog summary

Standards and Compliance
Ductwork passing through fire-rated walls or floors must comply with BS 476: Part 24: 1987, which requires ductwork to meet criteria for stability, integrity, and insulation. The fire rating is determined by the shortest duration of these criteria. Building Regulations Approved Document B3 and BS 5588: Part 9: 1989 emphasize the need for fully protected ductwork when air handling ducts pass between compartments.

Regulatory Requirements
BS 5588: Part 9: 1989 specifies that ductwork fire resistance should match the fire resistance required for the construction elements it passes through. BS 476: Part 24: 1987 outlines that fire resistance is measured by the duration until failure in stability, insulation, or integrity occurs.

Product Solutions
Rockwool’s Fire Duct Systems offer a cost-effective, single-layer insulation solution that meets required standards. Products like Fire Duct Slab, Fire Duct PSM, and Fire Duct Section provide fire protection with minimal weight and thickness, suitable for both vertical and horizontal duct systems.

This British Standard requires that any ductwork meets three criteria: • Stability • Integrity • Insulation For example, a system having 1 hour stability, 1 hour integrity and 15 minutes insulation is rated at 15 minutes only. The least of the three periods of compliance defines the fire rating. For ductwork passing through a fire rated wall or floor, no British Standard allows stability and integrity...
