Description

Aluminium Window – Design 18

1300mm to 3000mm wide, but only 450mm to 1400mm high — this is a distinctly horizontal window, wider than it is tall by a wide margin, suited to openings where height is limited but width isn’t.

The Shape of This Particular Opening

A maximum height of 1400mm against a maximum width of 3000mm gives this window one of the most elongated proportions in the range — think a long, low band of glazing rather than a conventional window shape. It’s the format you’d specify above a run of cupboards, along a stairwell, or anywhere the wall itself is constrained vertically.

Why Aluminium Holds Up Here

Holding a frame this wide rigid, at a comparatively shallow height, is precisely where aluminium’s strength-to-thickness ratio pays off — a softer material would need a noticeably bulkier frame section to avoid flex across this kind of span.

Locking It Down

The multipoint lock spreads its engagement points along the width of the opening sash rather than its height, which suits this elongated proportion — security isn’t compromised by the window’s unusual shape.

What It Does for the Room

A low, wide window like this tends to admit light without necessarily offering much of a view straight ahead — it’s often chosen for daylight and airflow in utility spaces, landings or storage areas rather than as a primary outlook window.

Fitted to This Opening, Not a Standard One

Built to a 1300mm–3000mm width and 450mm–1400mm height range — an unusual enough proportion that a standard-size window genuinely wouldn’t work here.
