AC duct manufacturing in Al Kawthar

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.

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.

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.

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.

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.

Fully sealed and insulated ducts maintain efficiency even in intense heat. Thick insulation greatly reduces external heat absorption, and Foster sealant on all gaps prevents cold-air leaks.

Yes, Al Kawthar's generous spaces need long ducts. We manufacture them in short numbered sections for easy transport and installation, with strong plenums ensuring pressure and balance.

Coastal insulation primarily protects against humidity. Al Kawthar and eastern areas need thicker insulation protecting foremost from intense heat and external heat absorption.

It depends on building height, unit count and spaces. We take full project measurements and design sections and plenums to balance pressure and ensure even distribution across all floors.
