Where a top hung aluminium window 2400 × 1200 works best
Large living rooms, open-plan spaces and elevations where a sliding door would be inappropriate but a full-width view is wanted. At 2.4 m it typically spans between two structural piers, so it often sits within a designed opening rather than being retrofitted.
Why a twin opener across 2400 mm
Two sashes across a 2.4 m span is the practical arrangement: each leaf stays operable, and the fixed and opening areas balance visually. It also limits how much glass is moving at any one time, which is a real consideration on an exposed elevation. It is one of the most specified sizes we build, which is why we keep the top hung aluminium window 2400 × 1200 as a standard catalogue item rather than a custom order.

Top hung aluminium window 2400 × 1200: fitting notes
The frame is manufactured at 2390 × 1190 mm. At this size treat it as a structural glazing decision, not just a window order: confirm the lintel, the bearing at both ends and the levelness of the sill across the full span. Handle and store the unit upright, and allow for at least two people plus proper lifting on installation.
Glass and finish on this top hung aluminium window 2400 × 1200
Every unit is glazed as standard with 6.38 mm clear laminated safety glass. Laminated glass holds together on impact because the interlayer retains the fragments, which is why it is our standard rather than an upgrade. The frame is powder coated in your choice of Black, White, Bronze, Charcoal or Natural Anodised.

Ordering this top hung aluminium window 2400 × 1200
This is a made-to-order unit with a lead time of 1–2 days from order. Aluminium windows and doors are supplied only — installation is arranged by your own builder or installer, which keeps the manufactured product separate from the installation contract. Collection is from Laser Park, Roodepoort, with Gauteng delivery and national supply options depending on the order and destination.
If your opening does not match this size, we manufacture to your dimensions — send the structural opening width and height and we will confirm what can be built. Final responsibility for measurements rests with the customer, so check the opening before ordering.
