Alu-clad windows cost in Ireland
In Ireland, a triple-glazed Scandinavian alu-clad window costs €1,100 to €2,000 per window supplied and fitted (or €1,000 to €1,500 per square metre). A full 3-bed semi-detached house (8 to 10 windows) runs €11,000 to €20,000, while a 4-bed detached or one-off self-build package (12 to 16 windows plus a lift-and-slide patio door) costs €16,500 to €32,000.

How quantity surveyors price alu-clad by the square metre (m²)
On architectural self-builds and extensions, window schedules are usually budgeted per square metre of glazed opening before exact sash counts are finalised. In 2026, installed triple-glazed alu-clad joinery averages €1,000 to €1,500 per m²:
- Fixed floor-to-ceiling screens (€850 to €1,150 / m²): No hinges, friction stays or multi-point espagnolettes — ideal for framing views at lower cost per square metre while keeping identical external aluminium sightlines.
- Top-guided or side-hung opening casements (€1,100 to €1,550 / m²): Includes heavy-duty concealed or stainless hinge gear and espagnolette locking.
- Lift-and-slide doors (€1,250 to €1,750 / m²): Heavy-duty 300kg roller carriages, flush fibreglass thresholds and 6mm/8mm toughened safety glass panes.

Questions homeowners & self-builders ask
How much can I save by changing some opening alu-clad sashes to fixed panes?
Every opening sash adds €220 to €380 in sash framing, gaskets, hinges and handles compared with a fixed direct-glazed pane. On a 15-window self-build, combining fixed picture panes with one side-hung opener per room regularly trims €2,500 to €4,000 off the schedule.
Does dual colour (e.g. RAL 7016 outside, white inside) cost extra on alu-clad?
Usually no! Because the external powder-coated aluminium cladding and the internal painted timber frame are finished on two completely separate production lines before assembly, having dark grey/black/bronze outside and warm white or clear lacquer inside is standard on alu-clad.
