Aluminium Doors & Windows — System and Custom Fenestration
Aluminium doors and windows are best specified as engineered systems, in which profile, hardware, gasket, drainage and glass are designed and tested as one assembly with published performance, rather than fabricated from separately sourced parts. In air-conditioned buildings, thermally broken profiles stop the frame conducting heat inward and attracting condensation.

What we deliver
System and custom fenestration — openable, sliding, casement and tilt-and-turn aluminium doors and windows, plus uPVC where the application suits it, for commercial, high-rise and premium residential projects.
We work on engineered systems rather than assembled parts. A window is a performance product: profile, hardware, gasket, drainage and glass have to be designed as one assembly, or nobody can honestly state what it will do.

System partner
As a strategic partner, Winda Window Systems supplies engineered aluminium and uPVC window and door systems manufactured in Ludhiana, Punjab. Systems are built as one engineered assembly — profile, hardware, gasket, drainage and glass — using 6063 T6 alloy, EPDM gaskets and EN-certified hardware.
Scope of works
| Stage | What we deliver |
|---|---|
| System selection | Openable type, performance class, thermal and acoustic requirement |
| Design | Opening schedule, shop drawings, glass specification |
| Fabrication | In-house cutting to ±0.1mm, routing, crimping, end milling |
| Glazing | DGU or single, coating and toughening per application |
| Installation | Sub-frame, fixing, sealing, hardware setting and adjustment |
| Handover | Operation check, snagging, O&M and warranty documentation |
What drives the cost
Opening type and size · thermally broken versus plain profile · glass build-up (single, DGU, laminated, low-E) · hardware grade and origin · acoustic performance requirement · finish (anodised versus PVDF powder coat) · floor height and access.
Where projects go wrong
- Mixing system components. Substituting a gasket or hardware set invalidates the tested performance of the whole assembly.
- Specifying good glass in a plain frame. Paying for high-performance DGU then bridging the assembly with unbroken aluminium wastes the benefit.
- Ignoring drainage. Water sitting in the glazing rebate attacks the DGU secondary seal and causes early fogging in monsoon conditions.
- Leaving finish grade unnamed. "Powder coated" spans products that last five years and products that last twenty-five. Specify the resin class.
