Casement windows are the UK's default replacement choice - hinged on the side, opening outward, and available in uPVC, aluminium or timber. If your existing frames are pre-2005 or single-glazed, replacing them with A-rated casements typically pays back in energy savings within 8-12 years.
The single biggest price driver is glass area, not frame material - a 1200x1200mm casement costs roughly the same in uPVC or basic aluminium, but doubles for triple-glazed or thermally-broken aluminium. Standard installs use argon-filled double glazing with a warm-edge spacer; upgrading to triple glazing adds around 15% for a marginal thermal gain in most UK climates.
