Description
Top Hung Aluminium Window 900 × 1200 mm Single Opener — made to order in South Africa and priced online, supplied direct by Coetz™.
Where a top hung aluminium window 900 × 1200 works best
Stairwells, passages, narrow bathroom walls and the flanking walls either side of a door. The vertical proportion suits a tall narrow pier of brickwork where a wider window simply will not fit, and it pulls light higher up the wall than a horizontal window of the same area.
Why a single opener at this proportion
A single sash suits the narrow width — splitting 900 mm into two openers would leave each one too small to ventilate usefully. Top hung is particularly appropriate in a stairwell or passage, where an outward-opening sash sits above head height and stays clear of circulation. It is one of the most specified sizes we build, which is why we keep the top hung aluminium window 900 × 1200 as a standard catalogue item rather than a custom order.
Top hung aluminium window 900 × 1200: fitting notes
Frame size is 890 × 1190 mm. In a stairwell, check the sill height against the going of the stair before finalising — a window that looks well placed on a plan can end up awkwardly low over the upper flight. Confirm the sash has clear outward swing at whatever height it lands.
Glass and finish on this top hung aluminium window 900 × 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, and the price shown already includes 20% off.

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.
