Coetz™ Top Hung – 1500 × 1200 mm – Twin Opener

Where a top hung aluminium window 1500 × 1200 works best

Bedrooms, dining rooms and studies. It is a common upgrade size when replacing an older 1500 × 900 steel window, because the extra 300 mm of height noticeably improves the view out and the light on the floor without widening the opening or touching the lintel.

Why a twin opener at 1500 × 1200

Two sashes across 1.5 m give balanced ventilation and keep each leaf light. At 1200 mm high the sashes have real area, so splitting them also keeps wind load on any single leaf sensible when the window is open. It is one of the most specified sizes we build, which is why we keep the top hung aluminium window 1500 × 1200 as a standard catalogue item rather than a custom order.

Top hung aluminium window 1500 × 1200: fitting notes

Frame size is 1490 × 1190 mm. If this is a replacement for a steel window, expect the existing opening to be out of square — measure width and height at three points each and work from the smallest. Old steel frames are often built into the brickwork and may need cutting out rather than lifting out.

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