Bifold doors fold concertina-style to open up entire walls onto patios and gardens — the defining feature of modern kitchen-diner extensions. S&K Glazing installs Smart Systems Visofold, Reynaers and Origin aluminium bifolds, plus Liniar uPVC bifolds, in configurations from 2-panel to 7-panel openings up to 7 metres wide.
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 doors and glass extensions in Londonderry, residential property style typically drives the design brief across Northern Ireland — whether that's contemporary aluminium bifolds spanning a garden-facing rear elevation, slim-frame sliding doors that maximise glass area on a modern extension, or heritage French doors fitted to a period façade. Most commonly we're working across BT47 and BT48 postcodes. Typical lead time from survey to install: 4-6 weeks for standard configurations, 8-10 weeks for bespoke or large-span builds.
We check structural opening, threshold level and floor finish to specify track, threshold type (flush, rebated or weather-rated) and panel configuration.
Choose number of panels (2-7), opening direction (left, right or split), traffic door position, colour and glass specification.
Origin bifolds: 1-2 week lead time. Smart Systems and Reynaers: 3-4 weeks. uPVC bifolds: 3-4 weeks.
