Coetz™ Top Hung – 1500 × 900 mm – Twin Opener

Where a top hung aluminium window 1500 × 900 works best

Main bedrooms, dining rooms and family rooms on a wall that can carry a 1.5 m lintel. It is wide enough to light a room properly without needing a corner or a second window, and the 900 mm height still allows a bed head, sideboard or dining chairs beneath the sill.

Why a twin opener across 1500 mm

Two openers give you cross-flow control that a single sash cannot. You can open the leeward side only on a windy day, or both for a through-draught in summer. Splitting the span also keeps each sash light on its hinges, which extends hardware life on a window that will be opened daily. It is one of the most specified sizes we build, which is why we keep the top hung aluminium window 1500 × 900 as a standard catalogue item rather than a custom order.

Top hung aluminium window 1500 × 900: fitting notes

Frame size is 1490 × 890 mm. At this width the centre mullion carries load, so the opening needs a proper lintel and a level bearing across the full span. Check that both sashes have clear outward swing — on a patio elevation a 1.5 m twin opener can foul furniture placed against the wall.

Glass and finish on this top hung aluminium window 1500 × 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.
