Services / Curtain Wall
We calculate, fabricate, and install aluminium and glass curtain wall. Wind load and water penetration are worked out at the design stage, before the facade shape is locked.
Send your facade drawing over WhatsApp. You get technical questions back, not a form.
The term gets used for any glass facade. Its technical meaning is narrower, and the difference shows up in the cost.
A curtain wall is a glass and aluminium outer wall hung from the outside of a building. It carries its own weight, the wind, and the rain, but none of the floors or the roof. Take the curtain wall off and the building still stands.
The frame is aluminium: upright bars called mullions, and cross bars called transoms. Together they form a grid, and each opening in that grid takes one panel.
The panel is usually glass. It can also be aluminium composite panel, metal panel, or stone. The gaps between panels are closed with rubber gaskets and sealant, and the whole frame is tied back to the floor slab edge with steel brackets.
What drives the cost is usually not the area of the facade. It is four other things: the height of the building, the type of glass, the distance between floors, and the shape of the facade. We calculate all four before quoting a number.
Two ways of assembling the same system. The choice follows building height, schedule, and how far panels repeat.
Mullions, transoms, and glass are assembled piece by piece on site. Material cost is generally lower and site changes are easier to absorb.
Suits mid-rise buildings, facades with many variations, and projects whose design is still moving.
Panels are assembled and glazed in full at the factory, then installed floor by floor. Precision holds better because assembly happens in a controlled environment, and site installation is far quicker.
Suits high-rise buildings with repeating panels, difficult site access, and tight schedules.
One team from calculation to handover. No hand-off between parties midway.
We review the architect's design, calculate wind load and frame structure, then propose alternatives that cut cost without lowering performance.
Detailed drawings for every joint, bracket, and interface with the structure, prepared for consultant and owner review.
Aluminium profiles come from the extrusion producer backing us, then are cut and fabricated in AFI's own workshop.
Performance Mockup Unit testing is triggered by height and exposure, so not every project goes through it. Where yours does, our team is experienced in running it at accredited laboratories, covering air leakage, water penetration and structural load.
AFI's project team supervises scheduled installation and quality control on site through to handover.
Our core team has spent decades calculating and installing high-rise facades.
Most come from owners and project teams comparing systems.
The section above compares curtain wall with window wall. When each one suits a building, and what changes in the detailing and in the quotation, is covered in Curtain wall vs window wall.
