External Bi-Folding, Sheffield

Industrial elegance meets contemporary living in a Sheffield home

Set within a beautifully restored Yorkshire stone property, this kitchen renovation brings together industrial styling and cutting-edge performance. Now transformed into a spacious, light-filled kitchen-diner, the space opens fully into the rear garden — thanks to the installation of iSteel’s AluFold bi-folding door system.

To maximise natural light and create a seamless indoor-outdoor connection, the homeowners opted for a striking set of aluminium bi-folding doors in a classic industrial style. Echoing the timeless appeal of traditional steel glazing, the design delivers ultra-slim sightlines alongside exceptional modern performance.

Fabricated using iSteel’s thermally broken AluFold system, the doors are fitted with double-glazed, toughened safety glass featuring a low-emissivity coating. This high-performance glazing helps to maintain comfortable temperatures throughout the year — reflecting excess heat in summer and retaining warmth in winter — all while meeting the latest Building Regulations Part L.

Finished in smooth matte black (RAL 9005), the nearly four-metre-wide bi-folding doors form a dramatic centrepiece, opening effortlessly to reveal landscaped garden views. When closed, they offer a strong architectural statement — enhancing energy efficiency, liveability, and the home’s distinctive character.
