Fire & smoke ductwork systems
Made-to-order ductwork, dampers and fire-protection components for ventilation and smoke-control applications—with practical support from initial drawings through to supply.
- Made-to-order ductwork
- UK-wide project supply
- Evidence-led system review
Start with what the ductwork must do
The correct route depends on the intended use and the project-specific evidence—not simply a fire-rated label.
Fire-resisting ventilation
Ventilation ductwork assessed for fire resistance where it passes through fire compartments.
Common reference: BS EN 1366-1Discuss your project →Multi-compartment smoke extract
Smoke-control ductwork serving more than one fire compartment, coordinated with the wider smoke-control system.
Common reference: BS EN 1366-8Discuss your project →Single-compartment smoke extract
Smoke-extract ductwork used within a single fire compartment and coordinated with the selected fan duty.
Common reference: BS EN 1366-9Discuss your project →Kitchen and specialist extract
Systems where fire resistance, grease, access, cleaning and project specifications must be considered together.
Project-specific evidence requiredDiscuss your project →
Compliance belongs to the complete system
The duct construction, size and orientation, pressure classification, supports, penetrations, protection method and installation details should all sit within the applicable evidence.
- Drawings and duct sizes
- Required fire or smoke performance
- System application and compartment arrangement
- Available specification or test evidence
- Smoke-fan duty where applicable

Fire and smoke ductwork FAQs
Which EN 1366 test route applies to my project?
That depends on the application. Fire-resisting ventilation, single-compartment smoke extract and multi-compartment smoke extract use different test routes. The project specification and applicable evidence should be reviewed before selecting construction.
Can DuctFix review drawings before manufacture?
Yes. Send the route, duct sizes, intended application, required performance and any project specification or evidence through the contact form.
Can I buy dampers and insulation online?
Yes. The relevant product ranges are linked above. For a coordinated project, contact us so ductwork and associated components can be considered together.
Is A1-rated metal ductwork the same as an EN 1366 tested system?
No. Reaction-to-fire classification and the fire performance of a complete ductwork system are different matters. The applicable tested system and project requirements should be checked.
