French Windows cost in Belfast
French windows (outward-opening paired casements to floor level) cost around 50–70% more than a standard casement due to the larger glass area and threshold detail.

Belfast note: Northern Ireland labour costs are lower than GB averages; ferry-inflated material costs partially offset savings.
