Description
Sliding Aluminium Window 2100 × 1200 mm 2 Panel — made to order in South Africa and priced online, supplied direct by Coetz™.

Where a sliding aluminium window 2100 × 1200 works best
Living rooms and bedrooms facing a patio, walkway or narrow side boundary. At 2.1 m it lights a room like a large top hung window would, but without an outward sash — which is often what decides it on a townhouse or complex where the boundary sits close to the building.
How a two-panel slider behaves at 2100 mm
Half the span opens, giving roughly a 1 m clear ventilation width. The larger panel size makes smooth-running gear and a clean track more important than on a smaller slider, since there is more glass weight riding on the rollers. It is one of the most specified sizes we build, which is why we keep the sliding aluminium window 2100 × 1200 as a standard catalogue item rather than a custom order.

Sliding aluminium window 2100 × 1200: fitting notes
Frame size is 2090 × 1190 mm. Confirm the lintel for a 2.1 m span and check the sill is level end to end before installation. Allow clear access along the full width for fitting, and plan for two people — a glazed 2.1 m slider is heavy and must be carried upright.
Glass and finish on this sliding aluminium window 2100 × 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 sliding aluminium window 2100 × 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.
