When duct quality makes the difference
- 1
Duct losing cold air
An open seam or an unsealed joint loses cold air before it reaches the room. We close every seam with Foster sealant in the workshop before shipping, so the seal does not depend on site work alone.
- 2
Condensation wetting the ceiling
In Jeddah's humid air any bare metal surface sweats and drips onto the ceiling or damages the unit insulation. We wrap with Kimmco or Armaflex at the thickness the site calls for.
- 3
A project with many duct runs
A villa or commercial building needs main trunks, branches and plenums in several sizes. We make sections in the workshop numbered to the site plan, so the hanging crew assembles without cutting or adjusting.
Who it's for
Replacing your villa's AC and need new ductwork
We make supply and return trunks and plenums to your villa's dimensions, insulated and numbered, ready for the hanging crew without any on-site cutting.
Ask on WhatsAppRunning a commercial fit-out that needs duct runs
We take your project drawings and produce numbered sections in batches matched to your site schedule, so the hanging crew is never waiting on supply.

How we work
How we work
- 1
Send sizes or drawings
Send us the duct drawing or a list of section sizes. If sizes are not fixed yet, we agree a site survey before production starts.
- 2
Review sizes and sheet gauge
We check each section's dimensions and pick the right sheet thickness for the duct size, then confirm quantities with you before cutting begins.
- 3
Fabricate, seal and insulate
We cut and fold the G90 galvanised sheet, lock the seams with Foster sealant, and wrap each section with Kimmco or Armaflex insulation in the workshop before shipment.
- 4
Number and deliver
We mark each section with its position and dimension from the site plan, so the hanging team identifies every piece without confusion and starts work on arrival.
Workshop-made or site-cut duct?
| Alrabih | The usual way | |
|---|---|---|
| Sealing | Foster on every seam in workshop | Uneven site sealing |
| Insulation | Kimmco or Armaflex fully wrapped | Partial or delayed wrap |
| Sheet gauge | Chosen for each duct size | One gauge for everything |
| Assembly time | Numbered, assembled straight away | Cut and adjust on site |
| Joint fit | Workshop dimensions close every joint | Hand trimming breaks the seal |

What sets this district apart
Al Shati is a relatively modern coastal district with luxury villas and large residential blocks with spacious interiors. Modern construction here demands advanced central AC networks, and high coastal humidity makes every duct and joint airtight essential. On-site duct cutting leaves gaps and cracks that waste cool air and trap moisture between walls and ceilings, whereas workshop-made ducts with full sealing ensure high efficiency.
Al Shati is a modern coastal district in north Jeddah marked by luxury villas and spacious residential blocks along the shoreline.
Most modern villas and blocks here have central AC systems with insulated ducts distributed through ceilings and interior walls.
The AC setup in Al Shati
- 1
Multi-branch distribution with sealed plenum
Modern villas and blocks here need a main duct from the sealed plenum with balanced secondary branches to each zone.
- 2
Balanced return ducts with pressure control
Return ducts are made with pressure-balancing dampers to ensure even flow from all rooms and zones.
- 3
Full insulation and Foster seal on every seam
All ducts and plenum are fully insulated and every joint and seam is Foster-sealed for protection against coastal humidity.

FAQ
Questions about AC duct manufacturing
How do you make sure the duct does not leak air at the seams?
We close the long seams with a tight mechanical lock as the sheet is formed, then seal every seam and every joint between sections with Foster sealant before insulating. Sections leave the workshop with matching flanges that tighten evenly when hung, because any small gap in cold duct means lost air and a point where condensation forms.
Does the duct arrive ready to hang, or is it assembled on site?
Sections arrive fabricated, insulated, sealed and numbered to the route drawing, so the fitters know where each piece goes without cutting or altering on site. What is left on site is joining the sections, fixing them to the hangers and connecting the unit and outlets, which shortens the work above the ceiling.
Do you make plenums for cassette and cabinet units?
Yes, we fabricate plenums for both types. A cassette unit plenum is measured to match the unit's outlet frame exactly so air reaches the branch runs without leaking at the connection. A cabinet unit plenum is made to carry both the supply and return paths if the design calls for it. Both types are insulated with Kimmco or Armaflex and sealed with Foster sealant before they leave the workshop.
Can you manufacture duct for a large commercial project?
Yes. The workshop is equipped to fabricate large supply and return trunk runs suited to commercial, government and industrial buildings. Each section is made to the project drawings, numbered and delivered ready to hang after insulation and sealing. When engineering drawings are available, the technical team reviews them before fabrication starts to confirm that the duct dimensions fit the ceiling voids on site.
Why are the duct sections insulated in the workshop before delivery?
The duct carries cold air through a ceiling void that may be hot and humid. Without external insulation, water vapour condenses on the cold sheet and drips onto the false ceiling or the goods below. So each section is wrapped in Kimmco or Armaflex in our workshop and every edge and joint is sealed with Foster sealant before delivery.
Are on-site cut ducts adequate for modern villas here?
No, on-site cutting leaves gaps that waste cold air and energy. Workshop-made ducts with Foster sealing ensure higher efficiency and energy savings.
With high coastal humidity, how do you protect ducts from mould and corrosion?
We fully insulate all ducts and seal every joint with Foster to block outside humidity, preventing mould growth and corrosion.
Large villas need complex systems, how do you handle the design?
We work with the engineer and contractor on the project plan and design a balanced duct network with primary, secondary and balanced return ducts.
Modern suspended ceilings have limited space, how do your ducts fit?
Before manufacturing we ask about available space and other services in the ceiling, and make ducts to custom dimensions without obstruction.
