Looking for steel windows in Londonderry? S&K Glazing has been installing across County Londonderry for over a decade. Steel windows — often called Crittall-style — combine the slimmest possible sightlines with industrial-aesthetic appeal.
Steel windows — often called Crittall-style — combine the slimmest possible sightlines with industrial-aesthetic appeal. Originally used in 1920s and 30s art deco and modernist buildings, they're now back in demand for kitchen extensions, internal screens, heritage refurbishments and high-end residential projects. S&K Glazing supplies and installs both authentic hot-rolled steel systems (W20, MW40) and slim aluminium look-alikes.
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 heritage and listed-property work in Londonderry, planning constraints frequently dictate the spec — we work within County Londonderry council's conservation area rules and listed-building consent requirements, using putty-glazed timber sashes, slim-sightline secondary glazing systems that sit invisibly behind original primary glazing, and steel-window restoration for Crittall-style frames. Most commonly we're working across BT47 and BT48 postcodes. We prepare the heritage statement and Building Regulations submission alongside our quote where it's needed for Northern Ireland conservation areas.
We help you choose between authentic hot-rolled steel (heaviest, most authentic) and modern aluminium look-alikes (lighter, thermally-broken, more affordable).
Steel sections cut and welded by hand, or aluminium profiles machine-cut. Lead times 6-8 weeks for steel, 3-4 weeks for aluminium.
Steel windows are heavy and require precision tolerances. Our team has 10+ years experience with W20 and MW40 systems.
