What new windows cost for your house
Two taps: the frame and roughly how many windows. The answer is a published Irish price times your windows.
Published price × your windows

How this is worked out
The number of windows you pick, times Expert Windows & Doors' published installed price a window for that frame. BuildTech's published price a window is shown next to it where it gives one. The multiplication is ours. Prices read on 3 November 2026. Neither page says whether VAT is in. Size counts: a big picture window or a bay costs more than a small bathroom window, and doors are extra. It's an estimate, never a quote.

Alu-clad
Timber inside, aluminium outside
An alu-clad window is a timber window with an aluminium skin on the outside. You get the look and warmth of timber in the room, and the outside never needs painting. The Irish Examiner puts the price order as PVCu, then timber, then alu-clad, with large windows or premium makes adding up to 30%.
Timber
All-timber windows
Timber windows look right on older houses and are often what the council wants on a protected structure. They need painting or staining every few years outside. Ask what timber it is, how it's treated, and what finish it arrives in.
