Kitchen Hood Ductwork Materials and Parts: Aluminium, Galvanised and Stainless Ducts, Elbows, Reducers, Clamps, Flap Caps, Fire Safety, Grease Traps and Costs in Pakistan
Kitchen hood ductwork is the set of pipes and fittings that makes a duct run, and the materials you choose affect safety, noise and how long the system lasts, especially with grease and heat from Pakistani cooking. This page covers aluminium, galvanised and stainless ducts, elbows, reducers, clamps, flap caps, fire safety, grease traps and costs. For route and size planning see kitchen hood ducting, for hoods see electric hoods and for cleaning see how to clean a kitchen chimney.
Duct materials
- Flexible aluminium. Cheap and easy to fit, but ribbed and noisy.
- Rigid aluminium. Smooth, light and corrosion resistant.
- Galvanised steel. Strong and common in rigid ducts, can rust if damaged.
- Stainless steel. The longest lasting and most hygienic, costs more.
- PVC duct. Only for non-heat zones, not recommended near the hob.

Fittings
Use smooth elbows rather than sharp corners, a reducer only where unavoidable, and clamps with sealant or foil tape at every joint. Choose a flap cap with a bird guard at the outlet. Keep fittings few to protect airflow.
Fire safety
Grease can catch fire in ducts, so use non-combustible metal near the hob, keep the run short and clean it regularly. Avoid plastic duct near heat. Do not route ducts through concealed combustible spaces without protection. Fit a metal section near the hood.
Grease control
A baffle filter in the hood catches most grease. A small drip tray or trap at a low point catches condensed oil. Check and empty it. Regular cleaning of the first section of duct keeps buildup down.
Fixing and support
Support long runs with clamps every metre, and keep the duct from touching walls, pipes and cables. Seal around the wall opening against dust and insects. A neat fixing reduces rattles and vibration noise.
What to check before buying
- Material. Rigid metal near the hob.
- Diameter. Matching the hood.
- Joint sealing. Clamps and sealant.
- Warranty. For parts and labour.
Before you decide
Choose rigid metal duct for the hob area, use few and gentle bends and seal all joints. Ask the fitter which materials are used and why. Good ductwork is hidden once finished, so quality matters more than looks. Fixed plumbing and gas work should be done by a licensed plumber or gas fitter.
