Looking for steel windows in London? S&K Glazing has been installing across Greater London for over a decade. Steel windows — often called Crittall-style — combine the slimmest possible sightlines with industrial-aesthetic appeal. For London properties near Heathrow, Gatwick, City, Luton, Stansted, we can specify acoustic-grade glass to reduce aircraft noise alongside thermal performance.
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.
London is our largest single market — 33 boroughs, five international airports, the M25 motorway and railway lines crossing every postcode. Our acoustic glazing dominates demand in flight-path postcodes near Heathrow (TW, UB, SW), Gatwick (RH, KT, CR) and City Airport (E16, E14). Plus commercial shopfront work across every high street and Zone 1-2 retail district.
For heritage and listed-property work in London, planning constraints frequently dictate the spec — we work within Greater London 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 M25, E16 and E14 postcodes. We prepare the heritage statement and Building Regulations submission alongside our quote where it's needed for London 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.
