Aluminium windows are the architect's choice for contemporary builds — slim sightlines, large pane sizes, structural strength and powder-coated finishes that last decades. S&K Glazing supplies and installs Smart Systems, Aluk and Reynaers thermally-broken aluminium windows for residential extensions, commercial buildings and high-end refurbishments.
Londonderry's 17th-century walled city, Georgian Bishop Street, and Victorian Waterside generate heritage-led glazing demand across BT47-BT48. Listed-building consents and timber sash restoration form the bulk of our work in this Northern Ireland walled city.
For window-replacement work in Londonderry, the property mix across Northern Ireland ranges from period stock through to modern new-build, so we specify the thermal solution per property — A++ rated double-glazed sealed units for standard upgrades (U-value 1.4 W/m²K), A-rated solar-control glazing for south-facing elevations, and triple-glazed argon-filled builds achieving 0.8 W/m²K for owners targeting near-Passivhaus performance. Most commonly we're working across BT47 and BT48 postcodes.
We work from architect's drawings or survey your existing openings to specify profiles, glazing and finishes.
Custom-cut and assembled to your exact dimensions using Smart Systems, Aluk or Reynaers — lead time 3-4 weeks.
