Looking for steel windows in Belfast? S&K Glazing has been installing across County Antrim 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.
Belfast's Victorian and Edwardian terraces, the modern Cathedral Quarter regeneration, and the post-Troubles commercial expansion drive glazing demand across BT1-BT17. Heritage sash restoration, commercial shopfronts, and large-volume re-glazing on the urban estates all feature in our Northern Ireland workload.
For heritage and listed-property work in Belfast, planning constraints frequently dictate the spec — we work within County Antrim 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 BT1 and BT17 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.
