Smoke Extract Ductwork — Built to Keep Working in a Fire
Smoke ductwork has one job normal ductwork never faces: it must keep moving hot smoke while a fire is burning, holding its integrity at elevated temperatures so firefighters can see and occupants can escape. We manufacture and install smoke extract ductwork systems to the ratings, temperatures and durations your project's fire strategy defines.
Where smoke extract ductwork is used
- Car park extract systems with smoke clearance duty
- Smoke shafts serving corridors and firefighting lobbies
- Basement and plant room smoke clearance
- Atrium and shopping centre smoke control systems
- Kitchen extract routes with a smoke control function
Smoke duct is a system, not a product
A smoke extract rating belongs to the whole installed construction — duct gauge, joints, hangers and penetration seals together. That's why we offer smoke ductwork on a manufacture-and-install basis: one organisation accountable from workshop to handover.
Working alongside your fire engineer
We price and build from your fire strategy, mechanical specification and drawings. If your project also needs fire rated ductwork protecting compartment penetrations, we regularly deliver both. Send us your fire strategy or call 07710 984 957.
Frequently asked questions
What is the difference between smoke extract ductwork and fire rated ductwork?
Fire rated ductwork protects the building by preserving compartmentation when duct passes through fire walls and floors. Smoke extract ductwork goes further — it must actively keep working during a fire, carrying hot smoke at elevated temperatures for a defined period so escape and firefighting can continue. Many projects need both, and we supply both.
What temperature ratings does smoke extract ductwork need?
That's defined by your fire strategy — commonly expressed as a temperature and duration such as 300°C or 600°C for 60 or 120 minutes, depending on the application. Send us the specification and we'll confirm the appropriate system construction.
Do you install smoke ductwork as well as manufacture it?
Yes, and for smoke systems we strongly recommend it. The supports, joints and penetration details are integral to the tested rating, so having one accountable supplier for fabrication and installation keeps the certificate meaningful.
How do I get a price for a smoke extract ductwork package?
These systems are priced from project information rather than online. Send your drawings, fire strategy extracts and specification through the contact page, or call 07710 984 957 to talk the project through first.
