Coetz™ Top Hung – 1200 × 900 mm – Single Opener

Where a top hung aluminium window 1200 × 900 works best

Bedrooms, studies and small living rooms. The proportions suit a wall where furniture sits beneath the sill, and the 900 mm height keeps the head of the window clear of a standard 2.1 m door head running along the same elevation, which matters visually more than people expect.

Why a single opener at 1200 mm wide

A single sash across 1200 mm gives one generous vent rather than two modest ones. For a bedroom that is usually the right call: you get a wide, unobstructed opening for night ventilation, and only one handle and one stay to operate. It also leaves the glass line uninterrupted when the window is closed. It is one of the most specified sizes we build, which is why we keep the top hung aluminium window 1200 × 900 as a standard catalogue item rather than a custom order.

Top hung aluminium window 1200 × 900: fitting notes

The manufactured frame is 1190 × 890 mm. On a 1200 mm span the sash is wide enough that the friction stays do real work — make sure the opening is square before ordering, because a frame packed into an out-of-square opening will bind at the corner first. Measure the brickwork at three points across the width.

Glass and finish on this top hung aluminium window 1200 × 900

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.
